Ford F-150 - 1997-2003 :: 2001 - Grinding Noise - Code P0403 - COPs Not Working?


Nov 18, 2015

2001 f150 extended cab flareside 4x4 4.6L v8, M5od manual, 196,539 miles this morning. the clutch slave is going out so I have some grinding and extra noise but recently the motor began to run like crap. I took it and coded it. "p0403, cylinder 4 misfire" is what it read on the obd scanner screen... I had a similar issue with the COPs not working and actually allowing water into the spark plug cylinder. I replaced them all at 100,000 miles or so with new motorcraft plugs at that time.

Fixed the problem and nothing since that time. Not sure why I did them all but I did. i was dumber 96000 miles ago. I also took down the intake and cleaned all the ports and crap out of it also. Yesterday took out #4 (on passenger firewall) and it looks fine. No evidence of leak, spark plug a light tan, firing well without problems, and even gaped properly still. My question is first I understood the p0403 to be EGR related, not cylinder #4 misfiring...seems odd.

2nd: I'd like to avoid just throwing parts at this problem. The EGR is simple enough to replace and if that's what is needed so be it. I'd rather do it right the first time. I've checked all of the vacuum lines, fittings, attachments. No leaks detected with smoke/brake fluid tests either. Good suction at the PCV, all good.

Ford F-150 - 1997-2003 :: 2003 - Running Sluggish Even Replaced Plugs / Cops And Cleaned MAF Sensor?

I've tried everything I can think of and it still runs sluggish.

1. Had dealer change plugs
2. Changed Cop's
3. Cleaned MAF sensor

The 5.4L has slight miss and doesn't respond well at all when trying to pass or going uphills.

Ford Escape / Hybrid :: 2004 - P0403 Code Came Up For EGR Solenoid

P0403 code that came up on our 2004 Escape 3.0.

Weekend before last I dropped the oil pan, cleaned it and the pickup screen out, and replaced the gasket (switching to full synthetic has been a double edged sword with the leaks that are popping up...); put in new plugs new upper intake manifold gasket and cleaned the throttle body and manifold out. All vacuum hoses inline with the EGR solenoid have also been replaced since the light went on.

While driving the following day the check engine light (CEL) came on and when checked at pep boys read P0403 (no other codes for low EGR flow, etc.). Now, the EGR solenoid is the newest non-regular maintenance item under that hood because the same code came up a couple of years ago (a new solenoid from pep boys fixed that lickety split) so I wasn't overly concerned that it had popped up again, but a bit frustrated that the solenoid only lasted as long as it did. Also, since the light popped up, I have replaced a couple of vacuum lines with some generic 4mm ID (5/32", I think) rubber vacuum hose, but that just headed off what looked like some potential future problem leaks.

Now, here I am a couple of weeks later having tried 4.5 new solenoids (Amazon sent me one with the wrong wiring harness clip so I couldn't verify that it was connected when it didn't work), and thrown some other "just in case" parts at it (new EGR valve and flow sensor, but these may be returned, but may just end up keeping them on, we'll see how things work out). I'm getting a solid reading from the hot lead on the solenoid harness at idle and during static revving, but I can't seem to get anything on the ground pin.

I've cleaned the connections and the larger pin block going into the top of the firewall to no avail. Should this read as a fluttering ground signal all the time, is it only grounded exactly when it wants the solenoid to open the EGR? What can I do to confirm that it should read grounded so I can know one way or the other whether there is a break in the line? I can't find my multimeter (or just dreamed that I picked one up last year). I'm also curious as to whether or not there's a good way to bench test the solenoid. I don't really get a reaction when I hook it up to 12v directly like I do with a vacuum solenoid from my Saab where there's an audible "click."

Is the wire harness for the solenoid a known weak spot? I've found two potential donors at the local junk yard that I can cut the wires out of to play around with/solder a new one in if that's something that the consensus deems may solve my cause. I also had an ABS light come on not too long after the CEL, but when I reset the CEL the ABS light went away and never came back (it only came on when I hit a big expansion joint on a highway bridge, no braking issues since it's been reset and ABS seems to be fully functional, per gravel road test). I still can't seem to read any ground signal at the solenoid harness at idle or with throttle input. I'd like to fix it, but don't want to start digging into the wires blind.

Ford Escape / Hybrid :: CEL Code P0403 - EGR Control Circuit Malfunction

After about 6 months I finally got the alternator replaced in the Tribute. I totally forgot about the CEL that was on for EGR Circuit. I've found a couple of pages ( OBD-II Trouble Code: P0403 Exhaust Gas Recirculation Circuit Malfunction ) that explain how to diagnose the issue but I was wondering if any other route for something that may be more common than another thing.

Ford Escape / Hybrid :: 2004 V6 - Code P0403 EGR Circuit Fault

I'm pulling a P0403 EGR circuit fault on a 2004 v6 Escape.

Last night I changed out the EGR solenoid. Cleared the code and drove around for a while, got on the highway and cruised for a few miles and everything seemed fine. Turn the car off and back on and the code showed up again.

My next step will be to check the electrical connection to the solenoid. I don't do a lot of auto repair.

With my multimeter I will check for 12 volts. But from what I understand I can not check ground as the PCM sends ground to the solenoid to activate it. How should I check the electrical connections to the EGR solenoid?

Ford F-150 - 1997-2003 :: Grinding Noise On Passenger Side

I'm trying to find out why my truck has a grinding noise on the passenger side when my truck first starts driving for the first 1/4 mile. It stops after that or when I apply the brakes. Do I have a brake sticking or something more serious?

Ford F-150 - 1997-2003 :: 2002 - Grinding Noise From Front Differential

I have a 2002 f150 5.4 with 3.55 limited slip... For months now every time I hit a bump with the front right side there is a loud bang (sounds like a wore out bushing), and if I am driving slow at an idle you can here a thump every time the wheel goes around. And when I turn all the way it sounds more like a grinding sound.... The noise is getting very bad, what it is. I am very mechanically inclined but cannot figure it out.

Everything in the front end seem tight. When I lay under it if I get someone to spin te wheel the thump sound sounds like its in the front dif, kinda echoes through the front drive shaft but u joints seem good. I really think it's in the dif, and I'm hoping the banging noise I hear when I hit bumps is the same problem as the noise when the wheels go around....

Ford F-150 - 1997-2003 :: 1998 - Grinding Noise After Starts For About 3 - 5 Seconds

I recently sold me 91 F-250 and got into a 98 F-150. It's a SuperCab 6.5' bed, 4x4 off-road, 3.55 gears, 5.4 v8 auto. I love the truck, but I am having an issue with a noise at startup.

Every time I start the truck it fires right up but it makes a grinding noise AFTER it starts for about 3-5 seconds. I thought the starter wasn't disengaging in time so I replaced it. The starter I took off was fairly new. It's teeth had just a little wear and the flywheel had no visible wear. I put in the new starter and there was no change at all.

I also changed the oil and filter using Motorcraft 5w-30 oil and a Motorcraft filter. I also started it without the serpentine belt to rule out a pulley bearing. What the noise could be? The truck runs absolutely excellent, by the way.

Ford F-150 - 1997-2003 :: Intermittent Grinding / Dragging Noise Coming From Pulley

1997 4.6L.. Have an intermittent grinding / dragging noise coming from the pulley (?timing) area that I'm trying to pin down. Both the alternator and tensioner were replaced prior to the noise starting. The ac compressor and the power steering pump are original. The fan clutch was replaced about 4 years ago and the water pump 8 years ago. Timing chain / guides / tensioner are all original.

I don't notice any of the common ps pump indicators (whine increase when steering) but noticed the fluid level was down slightly and that the pulley seems to have some inward - outward play with the belt off. I also don't have any other engine symptoms like rough idle or any codes being triggered. How to isolate the culprit?

Ford F-150 - 1997-2003 :: Horrible Grinding Noise When Turn The Wheel Either Direction

I may, or may not have had to jump a curb at 40 mph to avoid rear ending another car. Truck is a 2003 F-150, single cab stx package, 4.2ltr. Long story short, no damage to my passenger side front tire or rim that I can see, but I do have a horrible grinding noise when I turn the wheel either direction. The truck still turns properly, power steering fluid is level. What should I start replacing first?! She's got about 90k miles on it, I'm sure a lot of the suspension parts are due, just need to know where to start!

Ford F-150 - 1997-2003 :: 2000 F150 - Grinding / Squeaking Noise When Backing Up?

I have a 2000 F150, 94k miles, manual transmission, 2WD

About 6 months ago a slight squeaking sound started when only backing up. Now its progressed to a sort of grinding metal on metal sound with regular driving as well as in reverse. I can hear it the most when its in gear and I take my foot off the gas. I changed the breaks, checked the wheel bearings, did a clutch test, and the u joints look fine. Something weird happened yesterday, while raining out, it didn't make a peep. My drive shaft and u joints have a layer of rust on them...could that be a cause of the noise, and it went away when wet?

Ford F-150 - 1997-2003 :: Grinding Noise Coming From The Area Where Transmission And Motor Meet?

I have a 97 250 LD 5.4 that suddenly has a grinding noise coming from the area where the transmission and motor meet. I took the inspection plate off the transmission and can look up inside there and see everything moving. I use a screw driver and if I flex the plate that mounts between the transmission and the motor I am able to get the noise to quiet down until I release the screwdriver and then the plate flexes back and scrapes making the noise again.

I can not see where the plate is grinding when I look up inside there. I can't figure out how to fix this.... Why it would just start doing this on its own as none of the bolts on the housing have been removed except for the two bolts that hold the starter on. (Changed it a couple of weeks ago). Thought about loosening the bolts on the tranny housing but I'm afraid that it would open me up to further problems???

Ford F-150 - 1997-2003 :: Passenger Side Brake Started Making A Grinding Noise

I have a 1997 F150 (truck in signature). In December my passenger side parking brake cable broke so I replaced both rear cables (front cable appears in good condition).

This past Friday the passenger side brake started making a grinding noise so I pulled the drum to find the self adjuster cable broken and the ratchet jammed between the shoe and the drum. I pulled everything apart and put new shoes (the pin the ratchet pivots on was broken off the rear shoe)and all new adjusting hardware (adjuster screw, ratchet, cable, and cable guide). The rest of the hardware looks in good condition (still paint on the springs and retainers). I got everything put together and took it for a test drive, it had a nice firm brake pedal (it's been a while since this truck has had a firm pedal) and great stopping power.

Took it to work today, and on the way back I stopped to pickup a package from the UPS store. I set the parking brake and put the truck in 1st like I always do. When I got back out to the truck to drive home, I released the parking brake but there was still obvious drag as I drove home (no good place to stop during rush hour), got out of the truck and it reeks of burning brakes. I pulled the driver side drum off (after it cooled), which was rather difficult, and everything looks to be in order except the rear shoe was not touching the post at the top of the backing plate. I checked and the adjuster was still all the way in, so that isn't the issue.

I pulled the parking brake cable out to slack the drum side of it (with the pedal released there is some spring tension from the pedal mechanism) and clamped it with vice grips so the cable was slacked and the shoes were then touching the post, and the drum could be installed and turned relatively easily, I then removed the vice grips and let the spring pull the tension out of the cable and the brake held firmly (requiring considerable effort to turn the drum). Is there anyway to adjust the spring tension on the parking brake cable when the parking brake is released?

Additional notes: when setting the parking brake, the pedal will only go down an inch or 2 before the brakes are locked up tight and the pedal won't move, it used to go down several inches before. also I noticed that the feral on the end of the drivers side cable (that locks into the lever attached to the rear shoe) is deformed, like the cable has too much tension on it. The cables are the correct ones for my wheel base according to Autozone but I'm starting to wonder if they are too short. Spring tension on the parking brake cable (when the brake is not set) causes the parking brake to drag. How do I get the parking brake to stop dragging? ("star" adjusters are new and adjusted all the way in).

Ford F-150 - 1997-2003 :: 2001 - A/C Won't Working?

The AC on my 2001 F150 didn't work correctly so I bought a gauge and a bottle of AC juice and decided to charge the system. The AC starts out cold and turns warm. I put the gauge on the system and the needle goes to the red portion of the gauge. The AC will turn warm.

Is there a relay switch that quits functioning? Is there a code I could look at to determine the problem?

Ford F-150 - 1997-2003 :: 2001 2WD - Heater And AC Not Working

I have a 2001 F150, 2WD, 5.4L. Neither the heat nor the air conditioning works. The blower works fine on all settings, and the air blows out of the correct ducts in accordance with the switch settings. The problem is the heat does not blow hot, and the AC does not blow cold. Everything is just the temperature of outside air.

If I jumper power to the compressor at the relay socket in the fuse box, I can make the compressor run and it provides cold air. The relay does not seem to be the issue because replacing the relay does not work. The heater core is hooked up, just no hot air.

I was thinking maybe the problem is in the temperature level switch in the dash panel. Does that sound like the best possibility? Do you think these problems are connected, or am I looking at two different issues.
