I have a trouble code of 446 and can't find the wiring for the solenoid valve at the canister. I think I should have constant 12 volts and the computer is regulating the ground. but I don't see the constant 12 volts. I don't have a wiring diagram so don't know where it is supposed to come from.
View 4 RepliesTruck is a 2008 F150 5.4 4x4. I changed the spark plugs the other night for the second time. Everything went smoothly. Got the truck put back together and cranked it up afterwards to let it run. Truck ran great, but as the engine temp got up around 150 degrees, I started hearing a very loud ringing sound. I shut off the engine, double checked all connections, removed the belt to rule out accessory drive noise. No luck. The noise stays constant regardless of engine RPM, so I decided to drive it. I found the noise fades away under load, then returns as soon as I let off the throttle. I attached a GoPro to a cross member near the transmission after narrowing the noise down to the bell housing area.

We've had a lot of rain here in pa lately and i hit a few big puddles the other day and now i have a growl slash wine in the front of my motor,now i narrowed it down to something driven by the bely because I removed the belt and no noise all pulleys feel good and smooth except the ac compressor if you spin it by hand it has a rough/dry feeling and sound to it but the noise doesn't change with the ac on or off its just constant grinding/whine. Replace the ac compressor pulley bearing that what I am thinking it is and don't really want to change out the whole compressor..
View 1 RepliesAfter installing new glow plugs, glow plug relay, and valve cover gaskets my 2000 7.3 is throwing the 1395 code. Glow plug monitor Bank 1. Any input as to cause? Checked all connections to relay. All tight. Read something about fusible link. Where that is located? One side of relay reads 0 volts.
View 4 RepliesHad this truck a few years now, and it has always had a slight miss/hesitation and maybe a few codes. The timing chain skipped a tooth and the truck was down for about a year. I have 4 other trucks, so it wasn't a big deal. I finally had time to put a new oil pump, chains, guides, tensioners, phasers etc. The truck actually runs very well and quiet. But, now misses far more than I remember it doing.
When driving in town constant at 25-30 mph occasionally it will loose power for a brief moment(<1 second) and then be fine, the security light on the dash turns on for a few seconds. It drives at 55-65 just fine, unless I am going up a hill or something else increasing the load.
2004 5.4 3v 2wd
CEL-
P0453 (fuel tank pressure issue)
P0351 (ignition coil a primary/secondary circuit malfunction)
P0356 (ignition coil f primary/secondary circuit malfunction)
The coil packs are new, and I have injectors on order. Also found this thing on the back of the motor, it connects to the fuel rail on the drivers side. Where it should go. I looked on my other trucks. But my other 04-4wd has a box by the battery it connects to, but mine doesn't have any of that stuff. And my 08 doesn't have anything like this at all.
And a pix of the truck in question.
My 2008 Prius has started making a noticeable soft whirring sound whenever the engine is running. You can hear it both inside and outside of the car. The sound lasts exactly 30 seconds, then pauses for 4 seconds, than repeats . When the car is turned off, the sound can be heard for about another 10 minutes before it shuts off entirely.
View 2 RepliesSometimes (but not always!) when I turn my Prius (2008) off and open the driver door, there is a constant beep. There are no interior lights left on. I think whatever I am doing wrong might be draining the 12v battery as it keeps going flat.
View 4 RepliesI have 2004 w12 phaeton and when i start car voltmeter shows like 13 volts and when it takes like 20 seconds to reach 13.8 and if I push on gas little bit it goes right on 13.8 or 13.9
So my question how many volts should be if all system works fine? and how long after start should take to go 13.8? Could be that my batteries going bad?
I am attempting to wire a set of LED daytime running lights and was hoping to go through the fuse box. No luck so far trying to find a 12 volts that turns on when the key is turned.I have tried to tie into the fuse on both the radio fuses and the fog light fuse.There is 12 volts even when the key is not turned so when I wired the lights off these fuses , it would light the leds all the time. Is there another fuse box?
View 1 RepliesI was on the way back from the weekend trip and got a service engine soon light. I didn't notice any lack of power, rough idle or hard starting cold or hot. So we pushed on home. I checked the codes and it is the P1211.
Doing some research it seems the ICP is not as expected so I hooked up my phone with the Torque app and the IPR and ICP seem to be close to normal at idle and running. I din't see any high IPR %.
At idle the IPR was around 15.5 cold and 10.1 after a short run to the store and back when it warmed up a bit. ICP was around 690-720 cold and 470-490 when i got back.
Does that seem like normal readings? I cleared the codes and the CEL comes back on right away after starting the truck. I do have a TS performance chip that I will take out and see if that could be causing any problems. What else should I be looking into?
Check engine light came on this week. Said B1484 code Brake pedal open circuit..
I tried disconnecting the battery for a few minutes to reset but light came right back.
What a p0171 is?
View 2 RepliesI just bought a F150 with 103,000 on it. The engine is a 4.6. I get a P0605 code every now and then which doesnt effect performance. I erase the code and it doesnt appear again for maybe another 100 miles.
I suspect a loose connector but not sure. Looked up the code and it reads PCM READ ONLY MEMORY (ROM) ERROR. My question is what does the PCM operate? And wheres a good place to start troubleshooting?
Ok I have a 2004 F150. The airbag was flashing 42, I have since replaced that sensor and now its flashing code 16. I have searched everywhere and cannot find the answer to my question. Any clue as to what this code is trying to tell me. Lost 1, this is lost 3, are you lost 2?

View 3 RepliesThis started a couple of weeks back. It started with 3 codes, a misfire, bad coil and stuck rich. I have since done a tune up replacing all the spark plugs, the bad coil and even the O2 sensor. It is now at a point where the CEL is not on but it still throws the P2196 with a brand new o2 sensor just installed. I am stumped as what I should be checking for next. It seems to run ok but idle is not as smooth as pre-codes. The truck is a 2006 XLT..

Door closes tight and air gets hot when raising EATC temp control. I have run the reset and checked the code several times. Just keeps coming up with a 22 and 66. Also, This pickup has a brand new AC system and it doesn't cool for anything. 55F. after ambient temp crosses 90F.
View 4 Replies2006 F150, FX4, 5.4, super crew. Had the infamous airbag code 42 flashing at me the other day, replaced the sensor in the front of the radiator support, and am still getting the same code. The old senser had some corrosion inside the sensor itself, but the connections were clean on both the sensor and the pigtail. Is there something I may have missed?
