Ford F-150 (2004-2008) :: 2005 - CEL With Code P0446 And ODB2?
Apr 24, 2012
I have a 2005 ford f-150 5.4 l that the cel light came on. when it first started it did not give me a code but said I had a small emmisions leak. In a day or two it finally gave me a code (p0446). I pulled out the evap control purge solenoid to ensure that it was not plugged. I checked the voltage @ the plug/ with the key on it is giving 14 volts. when i plugged the valve in it would not shift. I took the valve out and jumpered it directly to the battery and it seems to work fine but when I plug it into the harness it does not work, I Cleaned all connections I could going back to the pcm and doublechecked voltage @ the plug and still have 14 volts but will not fire the solenoid. the coil omhs out @ 63omhs. I am going to try a new valve....

I got a Ford f150 and getting the error code P0446 Evaporative Emission Control System Vent Control. My truck has burnt up 3 of these things already in the last 8 months. Why my truck keeps killing them?

My service engine light is on and the tech at Quick Lube said this is the error code that is reporting. "P0446 EVAP Control System Vent Control Circuit Malfunction". Is the car safe to drive?

I do not feel any difference in the transmission performance but the code has been cleared twice and keeps returning so the symptom is persistent. Can't find the 08 sub-code on the internet anywhere so guess I will have to visit the dealer.

I have a 2005 F150 Fx4 5.4 that keeps throwing a p0172 code. I've replaced all spark plugs, C.O.P's, fuel injectors, Mass airflow sensor, 1 o2 sensor, checked all vac lines and there ok.

I just acquired a wonderful 2005 F-150 XLT 4.6 liter truck. I need to get it passable for smog check here in AZ and the failed test revealed a P0453 error code (EVAP) which translates to a possible pressure sensor malfunction.
My question is finding the sensor and if I am looking at dropping the fuel tank to service/replace the sensor. Also, could a vacuum line be the cause?

Today my Check Engine Light came on for the first time in years on my 1998 Ford Ranger. It has 363,000 miles on it. But the engine was changed about 150,000 miles ago. It's a 2.5 automatic. It runs good and has no problems until today. I was leaving a shop and when I started up the truck the Check Engine Light came on. It wasn't idling bad but when I went to take off it wouldn't hardly move. I wasn't even able to keep driving. So I stopped and turned it off and restarted it. Then the Check Engine Light was gone and it ran fine. I scanned it when I got home and it a Pending code of P0446.
I've never gotten this one before. It said something was wrong with the fuel vapor vent solenoid open or shorted. I've never replaced anything on the evaporative emission system except a hose under the hood 3 or 4 years ago. I've had to change the fuel pump a couple times. I've never had any wiring issues. I've never hacked into the wiring. I've owned it since it was new. Is it likely that solenoid is failing or the vapor canister is shot? I don't need this to happen again because even if it's in what was called limp mode. there's no way I could've driven it home like that. I couldn't even pull over. I was lucky I was still in a parking lot.

2005 f150 Lariat 4x4 5.4
Had phasers, tensioners, chains, guides, and sensors replaced. After driving the truck, it started to get a rough idle at low speeds, primarily in reverse. Changed both vct solenoids with no results. Started to get p0022 code. Changed the oil with motorcraft filter and 5w-20 twice after the work had been done, thinking it might need it. Vct's were a little varnished, but not too bad.
After a couple days of light driving, got a misfire on #3. Replaced the coil and it hasn't been back since. I am stumped at this point.
The computer show the timing to be at +13 when sitting stopped and in drive. It fluctuates a little, but not much. When the truck goes into a rough idle. The rpm's fluctuate wildly. It seems to be happening more frequently, the more I drive it.

Had the check engine light in the 2005 F150 (90,000 miles) come on. Got the code checked and its P0420. I know that has to do with the cat threshold levels etc. so I believe I am looking to replace the o2 sensor, if I am not mistaken.
How hard of a job is this? Ive done a decent amount of engine work and worked in a shop in high school. Just looking to see if that is the right thing to try first, replacing the sensor, before replacing the cat.
Also I know its the right bank, but if I am not mistaken there is a before and after the cat o2 sensor, which do i replace? Both?

2005 5.4L She would have a hard time starting before but after I replaced and fixed everything below she was running really good. Now back to sputtering, taking a long time to start and now not starting at all.
I have replaced; Fuel Pump, Fuel Filter, FPDM, Plugs and COP's, FRP Sensor, followed the power wire from the FDPM and found it corroded bad so I replaced it, also changed the ground location on the FDPM, I have checked all the wires from the FDPM to the drivers seat, checked all fuses.
I have power to FPDM and I have the diagram for the plug but how can I test (hotwire) the Fuel Pump without lowering the fuel tank? What should be the voltage coming from the FPDM plug? not sure about pin 1 & 6.
How can I test the FRP sensor? what are the specs for voltage?

Got this code a while back (several hundred miles) but have had no runability problems. I know it's the evap canister but my mechanic tells me it could be a myriad of things and he might spend hours on it and still not be able to resolve it. I plan on driving this truck til it's worn out. I've put 125,000 miles on it in 10 years almost all highway. I should be putting much fewer miles on now, only using it when I NEED a truck which should be less and less, mostly for hauling toys.
I hate to drive this thing another 10+ years with the engine fault light on but my mechanic says that if something serious goes wrong it will start to flash. A couple days ago the "check fuel cap" warning came on, but goes off if I hit,the odometer button. I got a new gas cap at Reilly's but it seems like a real POS compared to OEM, very light, and the check fuel cap warning still comes on.

I've checked the lines from the Purge Valve on the Passenger side of the Intake Manifold, Check OK
I've Checked that Valve OK
I've Replaced the Canister Close Valve
I've got the Gas Cap tight.
I've removed the rubber bushing holding the CCV to the Evap Canister, hoping to isolate the Filter and point the blame on it, no luck there!!
I'm thinking next is to drop the Tank and check over all the Goodies on top.... as much as I hate the thought of that, the two access holes under the seats, just don't allow access to enough of the tank!
any thing there that I could suspect, I see there's a check valve!
There's also the Fuel Tank Pressure Sensor, which may be at fault.

2000 Amigo 3.2L V6.
My check engine light came on, and I went to autozone to get the code read. The code was P0446, "a malfunction in the electrical circuit for the vent control in the evap emission control system." I was wondering if this could be a simple fix...would cleaning the EGR valve do anything to get rid of this? Maybe this could work, but before the light came on, the amigo was taking awhile to start up (usually 4 cranks, with me pressing on the gas). And oh yeah, the check engine light didn't pop up until after I let the car sit for 12 days, while I was on vacation.
I also have a side problem...when I turned on my car for the first time after my vacation, besides the check engine light popping up for the first time, my ABS light also came on. I've tried the whole turning off, turning on the car and driving real slow process, but the light remains on. It just seems really interesting that both lights came on right after my car was sitting for awhile.
I'm thinking about taking the amigo to the dealership to get it checked out.

2001 Camry 4 cylinder. Check engine light came on yesterday. Advance Auto pulled out the code P0446 for the evap. emissions system vent circuit.
The car has no symptoms other than this and is current on all maintenance, but obviously it is a 10-year old car and so it goes.

I have a 2001 1500 with the 5.3V8 motor (ext. cab sb 4x4 LT). I was my dads and had the service engine light on for a long time for the P0446 code. I replaced the vent valve and the purge valve and light keeps coming back on. Usually can go for a day or so and then it comes back on and I get the same P0446 code.

I have a 2014 GS350 F-Sport and having issues with odb2 port.
So I have a odb2 scanner that I have been using on my other cars but when I plug it into my 2014 gs, it doesn't even turn on. I took it to the nearest dealership to have them test it out and they were able to connect it using toyota/lexus computer through odb2 port....
My odb2 scanner is from 2006... is there a different version of odb2 scanner that I need to get?

My 2005 SuperCab 5.4 4x4 won't go into 4wd...I turn it on and nothing! No light, no clunk, nothing! (No 4Low either). I checked all the related fuses and relay fuses behind the passenger kick panel, and they are all fine. I don't do any off roading, nor have I ran anything over. The truck only has 20,000 miles on it.
I did have the brake booster hose recall a couple years ago, so I'm going to crawl under to see perhaps the technician didn't click a harness back together or something.
