Ford F-150 - 1997-2003 :: OD Light Began Flashing / Code P1728
Feb 16, 2016
It is a 1997 Ford f150 5.4 4x4 extended cab 175k miles. Took a 600 mile trip, first 300 no problems, then the "od" light began flashing, the truck shifted fine so I kept going, drove for about a 100 miles then stopped for fuel and read the code, (p1728) cleared the code and drove another 200 miles, no light no problem. The whole time there was no drivability issues. Yesterday I drove all over town, stop and go traffic, locking the TC and it would also unlock, no problems all day, drivability was fine. What to do?
1. Just keep driving it?
2. Does changing fluid fix this problem?
3. Rebuild the trans, because this was just the first notice.
4. Sell it quick no light and drives fine.?

To start I was driving to work tonight and noticed the o/d "off" light flashing. it shifted hard one time then felt normal the rest of the way to work. At red lights the o/d light world turn off and about 3 minutes later it would flash again. When I got to work, I checked my code reader which gave me the p0705. I have searched around the net for about an hour and one thing i am seeing is that the fluid is "hot" or that there isn't enough. i have checked it and it looks slightly low like right above the add indication.
The only sound I here from under the truck is a rattle when in drive and at idle, but once I give it some gas it goes away. On they way home that night the o/d light was still flashing but it drove fine just at higher rpm, it down shifted hard one time but there were no other issues. I checked the fuses and they are all good.

I have a 97 f150 (built 96 as 97 model), 4.2l 4x4, auto tranny. Here's the problem, when I turn my key forward to run position my starter kicks on and starts the truck, and stays engaged. I have a constant 14v at the signal wire on the starter relay (yellow red stripe). Also tranny started to slip, od light flashing. I replaced ignition lock cylinder, ignition/ starter switch, starter relay, starter, and today transmission range sensor (neutral safety switch 8 pin), same problem. Cel code that I had 2 days ago was P0707 tr sensor low input.

I own a 1998 ford f150 4.6l triton v8. I was leaving my house to go on a snowboarding trip about three weeks ago it was a rather warm wet day and all of the sudden my check engine light began to flash. I immediately pulled over and restarted my truck, once it was started again it was solid.
I turned around and started driving towards home. I get a small amount of feedback from my speakers and usually it's a smooth whizzing sound but as i accelerated the sound began to stutter rather than remain smooth. after about 5 minutes of driving this went away and the check engine light remained on.
so today I went out it's also a wet day and it's raining quite a lot. on my way into town everything seemed okay. then on my way home the check engine light began to flash again and the feedback from the speakers became choppy again.
I would also like to mention my battery light is on but it was on prior to the first time this happened. I'm just wondering if the belt could be loose or slipping due to the wet weather?

I had been having battery issues with my 97 ford f150 4.6 liter for the longest time, thought i had a short under dash, i pulled entire dash out, disconnecting bat first of course, and inspected all wiring harness connections and fixing my issues and putting it all back together. now with new bat and all put back together i am now getting the airbag light flashing 5 times then 2 times (error code 52) i know it has some thing to do with power failure or backup battery, but now with the new battery in i cant seem to get it to reset. How to do this?

Just today, my '05 Ford Focus began flashing in orange it's O/D Off light. It seems to only happen when I am going over 40mph between 1800 and 2000 rpms. The light flashes for no specific amount of time and doesn't come on at specific intervals. I have also noticed that the car is shifting (it's an automatic) in this RPM range as well. I am worried because I just moved to a new area and am unfamiliar with the automotive services in this area. Another interesting thing that has happened along with this problem is that prior to this, my oil light had been coming on periodically. When I had that checked out they told me it was the oil pressure sensor. However, now that light hasn't gone on and I haven't had that replaced. Am I looking at a lot of trouble ahead with this car?

I just bought my wife a 2010 GX 460 and noticed an issue today with 4 Lo. When sitting with the car on, and in park, I engaged 4 Lo. The 4 Lo light began flashing along with a dinging sound. It didn't stop when I put it in drive or reverse, and just continued. The manual states I need to take it into the dealership because there is a malfunction.

My 1999 Passat 1.8T (AEB engine) with 120,000 miles has run very well lately.............except for a recent problem. I drove 150 miles on southern California freeways, parked the car for an hour, then started it again. There was a distinct miss and the check engine light began flashing. I turned it off, let it sit for a couple hours, then plugged in a code reader. There were two codes, both the same - P-0302, "Cylinder #2 misfire". I pulled the cover off the engine, wiggled the wiring to the #2 coil, cleared the codes and started it up. There was no miss, maybe there was a little corrosion on the electrical connection?? I know there was a recall on the coils, but my car was too old to participate in the recall. Which it is - bad connection, bad coil, or something else? Or a way to diagnose it further?

Just wondering if this is possible, if the ABS light come's on now and then,
And the speedo bounces, as it does, could it trigger the dreaded OD flashing light.

'98 F-150 4X4 XLT began squeaking recently. Have 1/2 mile long sand & limerock driveway thru mature North Florida jungle & every root'n'bump makes it squeak.
Was certain it had to be the J.C.Whitney/Owen's running board I left on passenger side. Upon close inspection, wrestling with it & popping it with big rubber mallet was surprised to find it tight & silent.
Checked bumper & associated bolts, then exhaust & everything else I could see/touch sliding under on a moving quilt.
Does not sound like bushing or ball joint. High pitch squeak, up near the annoying frequency of nails on chalk board.

I've got a 2003 Ford Explorer The transmission O/D light is flashing, and the check engine light came on. I'm getting and Code of P0775 Pres. Ctrl Solenoid B Circuit Malfunction. Also it shifts rough between gears, the rpms ramp up to much before it shifts. What the problem is, and how to fix it?

Yesterday I replaced the bulbs in my heater controls, today I have the Airbag light on, flashing 2/7. And when I turn off the passenger airbag, the "OFF" light does not come on. I've heard if the "OFF" light goes out, you replace the switch, would that possibly cause this code?

Dashboard light is flashing. Sometimes it flashes sometimes it doesn't:no real pattern. It just started with no accident or jarring.

I have a 2001, 2wd, XLT, Super Crew with 4.6L and 180000Kms. I am the 2nd owner and have owned it for roughly 6 years. Since owning it I have towed the following: a 1500 Boat, 1000lb full utility trailer, a 2700lb boat, and most recently (Last summer) a 3500lb dry weight/4000lb full 22 foot camper trailer. None of these items ever caused me any problems til mis summer with the camper.
I have always got check engine lights for the stupid coil packs. It seems like I would replace one and a different one would go. I was camping one weekend a short hour distance from my home when I pulled onto the main highway and began to accelerate up to highway speed but it was feeling sluggish picking up to 100kph. When I merged onto the highway it was not a flat piece of ground and was a small grade of a hill, but nothing big. Before getting to the top I started to hear a strange noise, almost like a rattling, and the check engine light started to flash. After breaching the hill, it picked up speed, the light went out, and everything seemed fine.
This happened twice last summer with no other problems. At the end of the summer I once again had a check engine come on...I had blown out a plug, had it fixed and replaced 2 more COPs but still had codes showing for CC, M, F, O, OH, C, E and EV. My reader also said Freeze Frame, and MIL on. I had the truck in in Nov/Dec for an emissions test and it was given a conditional pass due to codes reading but no Check Engine light at this time.
I want to keep this truck...I will be towing the camper again, buit I'm considering getting a different truck. As it is I know I already have to have air bags installed in the rear to level out the load when towing. Hopefully that will cut back on some of the acceleration drag. At present time I have a check engine on...I'll check it again and post what its reading but most likely the same stuff.

I am trying to make sense of a P0741 code accompanied by a flashing OD light.
The truck is a 2002 (12/01) build date) F250, 7.3,4x4, Auto, with 245,000 miles on it. The truck seems to shift fine but around 40/45 it feels like the TC does not lock, followed by the flashing OD light.
The transmission was serviced 500 miles ago but the OD light flash was intermittent until last week, now its been constant. I want to take care of it before I do any damage.

My alarm and lights started going off one night. By the time I got to it, everything stopped. When I tried to start the next morning, I got nothing. After several tries, horn and lights started again. The only way to stop it was to disconnect battery.
One person told me that it was the key or the ignition not recognizing the key. I was then told that my truck, 97 f150, had no chip in the key so the problem was the computer.
I replaced my computer with a refurbished one. Once I hooked up the battery, the horn was still going, lights flashing and theft light still blinking. Also, not sure if its related, but when I try to use the key in the passenger door it turns, but there is very little resistance and the door does not unlock.

I got a 99 f150 with a 4R70W and 311,000 miles on it and last year the od light started flashing while I was going down the interstate so I checked the fluid when i got home and it was beyond burnt so i changed fluid and filter. So a month or so ago it started doing this thing where on take off it will rev up like its in neutral for a couple seconds then reengage and drive normal till i stop and start to take off again. It don't do it every time and it drives/pulls just fine other than that.

I have a persistent issue with the OD off light flashing on my 2001 7.3L auto 4x4. Scanning it with AE I get the P1832 code. The truck runs and drives just fine. It shifts nice, goes into overdrive, locks up, etc. If it weren't for that blinking light I'd think it was all perfect. I've checked all the connections, replaced the range switch / neutral safety switch, replaced the VSS on the rear axle, checked all light bulbs and fuses. I've checked MOST of the relays in the truck.
I pulled the tranny drain plug and poured out a bit of fluid into a clean pan, it looks and smells good. AE also tells me that it's not communicating with the ABS system (although there's no persistent ABS warning light on the dash), the Airbag, the Overhead Trip Computer, the Parking Aid (which I don't have...), or the Enhanced Powertrain. The temperature on my overhead display is reading -40F which is clearly wrong.
I've looked for a comprehensive wiring diagram for the truck, but can't find one. I'm trying to figure out if there's a connector or module that these various functions go thru that might be the problem. Am I missing a ground somewhere? The frame was just powdercoated......am I not getting a good ground connection? In complete disclosure, I have torn this truck apart and re-assembled it out of several different trucks as outlined in this thread.

I reprogrammed my computer, to get rid of a bad tune with the Ford Program. After reprogramming, and entering in my tire size/gear size my speedometer and odometer no longer work. Also my overdrive light is flashing. Does this truck have a PSOM and could that be bad? What else could cause the problem, it definitely happened when it was flashed. Whats the cheapest way to fix it?

The brake lights on my '02 F150 have started flashing spontaneously ie - with no one in truck. This lasts for a few minutes, then stops, but can start again a few minutes later. The fear of course is that someday lights could come on and stay on, resulting in dead battery.
I do have a trailer brake controller that has been on truck ten years. Read something on internet that brake pedal switch might be going bad (??). Any one else observed this strange behavior?
