Hi all I just bought a 2007 f250 5.4 V8. It has the codes P0018, P061b, and P2106. Has anyone had these codes before? The truck seems to run fine but has the codes. Tried clearing but they came back. Also, there's a small howl sound in the rear end. Let me know if anyone has had this happened or know what a solution may be.
Thanks!!

 

P0018 - Crankshaft Position - Camshaft Position Correlation - Bank 2 Sensor A

P061B - Internal Control Module Torque Calculation Performance

P2106 - Throttle Actuator Control (TAC) System - Forced Limited Power

 

The P061b, and P2106 codes can be set by a damaged or overly dirty air filter, or dirty MAF sensor. The P0018 code could simply be a bad cam sensor on the driver's side. The howling from the rear is a problem with the differential that can range from worn bearings to dirty/contaminated fluid.

 

Ok thanks. I've got the mechanics at my work taking a look at it. The one mechanic drove it yesterday and it overheated 4 times within about 30 minutes. I think they're gettin somewhere but this definately helps me help them narrow their search down!!

 

The P061b and P2106 codes were set as the result of the P0018 fault (in this specific situation) and are advisory.

Troubleshoot and repair the P0018 fault and the other two should also resolve.

 

None of the codes would give cause for the engine to overheat, there's something else going on there.

 

Ok. I'm thinking the cam phaser may be bad and this may resolve the issues. The temp gauge heats up fast when idling so I'm thinkng maybe the gauge or sender is bad.

 

So, truck was running good until last night...had a fire call and on the way home did a quick burnout in front of the station. About 200 feet before my house the temp gauge shot right up and the check engine light came on. Went and got it scanned today and the codes came up as
P1299
P1000
P1285
U1900

Maybe time for a new radiator or thermostat?

After the oil change was done the codes were cleared for that and stayed off. I cleaned the MAF sensor and air filter which was full of dirt and its ran fine since then. I put about 65 miles on after that so i think it just needed an oil change to get whatever dirt was in the motor out.

 

U0019 Controller area network (CAN) data bus: low speed bus

P1285 CYLINDER HEAD OVER TEMPERATURE (CHT) CONDITION

P1299 CYLINDER HEAD OVER TEMPERATURE (CHT) PROTECTION ACTIVE

P1000 OBD SYSTEMS READINESS TEST NOT COMPLETE

 

Any idea of what a fix for this might be?

 

Sounds like it could be :
1) a bad ground in the CAN bus system.
2) broken wire or lead in the harness
3) bad PCM.

These are my thoughts, hopefully someone with stronger electrical experience will sound in, I'd 1st start by looking at the plug at your PCM, unplug it, check for corrosion on the pins, use electrical cleaner on both the male and female side of the connector, use dielectric grease on the pins when putting it back together.. Now would be a good time to purchase the electrical schematics for the truck. You might get lucky and find the problem right away, but it's always been my experience, that tracing broken wires or bad grounds is always tedious. If you don't have time or don't want to try this yourself, I'd suggest a good local mechanic, with strong electrical / electronic background.

 

It's goin into the shop wednesday. I checked all the pcm plugs and they were clean. Hopefully the mechanic finds an easy fix!

 

Got new brakes put on and the truck seems to be running good. Thanks for all the help!!

 

Putting on new brakes fixed an overheating issue?

 

replaced the thermostat and cleared the code too. Only thing is that the whole truck vibrates a bit at high speeds like 80 mph
