So I recently bought a 2006 f150 with the 5.4 motor in it, previous owner said he did the timing job on it. I'm now getting codes thrown for advanced timing in bank 1 & bank 2. The truck runs and drives perfectly fine from what I can tell. I've replaced the cam position sensors, the vvt solenoids, and now I'm waiting on all new plugs and coil packs to come in. Has anyone delt with this issue before and what needs to happen to get it right? Thank you in advanced!!

 

What are the codes?

Did you try to clear them, if so how?

 

P0011 and p0021 I believe. I cleared them with a basic code reader. It also keeps throwing misfires on different cylinders which is why I'm replacing the plugs and packs today or tomorrow. Just hope I don't have to open the motor back up. I feel like if the timing job wasn't done correctly then there would be some noise coming from the chains and phasers, and don't think the motor would run smooth. I also don't know if the oil pump was changed or not when the timing job was done.

 

I realize you don't want to get very involved with this, but the only way to know is to start from the beginning.

We know something is causing the intake cam from returning to base timing from advanced. If a solenoid is sticking closed , or timing was off when doing the installation of parts.
We try the simple things first then move on to the bigger jobs next, If we are sure the solenoids are not blocked and cannot allow oil to drain, we might need to verify timing of all cams are where they should be . We don't know where the parts came from and that is always a consideration.Without the right tools to perform further tests, you don't have too much choice. Never hurts to obtain other opinions..

 

Yeh it's gonna be a fun project I guess. Thanks for your input. Imagine gonna change these plugs and coils then plug it into a forscan computer

 

Before spending a lot of $$ , if you feel the need to replace plugs and coils , your choice. Pretty sure those items will not have anything to do with an over advanced timing problem...When the solenoid is activated for that particular cam , timing gets advanced up at the phaser by lubricating oil directed there. When solenoid is deactivated, timing should return to base timing. If the timing marks are not lined up correctly, that could also affect timing. Don't fall into the trap of replacing good parts without good reason because that can get disappointing and expensive.
