So I have an 05 Expedition (I know this is the F-150 forum, but more visibility) that is throwing a P0022 and P0345. I get these point to the cam phasers, so before I throw $450 on a phaser kit and oil pump, I want to make sure its a good fix.

I have done a lot of research on this forum and other where people have replaced their phasers and it doesn't end up fixing the issue. So I just was looking to get some tips before I endup shot gunning parts.

 

The ECU determines P0022 (Camshaft Over retarded, Bank 2) from the feedback it's getting from Cam Position Sensor on bank 2. Code P0345 (Camshaft Position Sensor 'A' Circuit Bank 2) occurs from some difficulty getting a reliable camshaft position reading on bank2. I do not believe I would condemn Phaser's until I had successfully removed the P0345 code. P0345 code can come from a wide variety of stupid sounding things such as:


- Faulty Camshaft Position Sensor
- Camshaft Position Sensor harness is open or shorted
- Camshaft Position Sensor circuit poor electrical connection
- Variable Cam Timing (VTC) Solenoid
- Faulty starter motor
- Starting system circuit
- Dead (Weak) battery

I wouldn't trust the P0022 as very definitive until this condition, whatever it is, is resolved. The P0022 might not come back.


Good Luck

 

Thanks for your feedback.

I did take the solenoid out and it was not gunked up. I tested its operation with a power supply and it actuated as it should. I took it apart to make sure there was nothing inside.

I cleared the codes and went for a 15 miles drive and it hasn't popped back up, but the symptoms are still there. I am getting a slight miss when i am cruising under 2000rpm, and am down on power. I

 

I have also done quite a bit of research on here, and dealt with a few 5.4's. the conclusion that i have come to is that most people misidentify the source of the noise. For example, when truck owners ONLY replace their phasers, and it quiets the truck for a short period of time, and the noise returns, it could have been the VCT solenoids or a bad tensioner that robs the top of the motor of proper oil pressure. Or someone replaces phasers, but it turned out to be a damaged lifter. maybe a weak tensioner allows chain slap, and a piece of a guide fell into the oil pan, clogging the oil pump tube.

I believe that the best solution to this ticking problem, to ensure a quality fix, is to replace all of the front timing components. BUT BE AS SURE AS POSSIBLE AS TO WHERE THE NOISES/CODES ORIGINATE. a mechanics stethescope is a cheap and easy way to get an idea of where your motor is ticking. start out with the VCT solenoids, as they are a cheaper, easier job. (as i see you have already checked) if that doesn't work, change the phasers AND the timing components (chains, tensioners, guides)

while you have it apart, whether they are making noise or not, check the lifters and cam followers just to be safe.

im not recommending that you immediately throw parts at it, that is only if you decide to go with the phaser change.

Hope this helps!

 

As far as your codes go, F150torqued hit it right on the money. ive seen a truck throw these same codes, and it turned out that changing the cam sensor cleared them both. i believe it is because the cam sensor was not giving proper information to the VVT system, and it was making the VCT solenoids advance or retard the cams improperly.

 

Well I just pulled both cam sensors. no external damage. the drivers side was reading 360ohms and the passenger side was reading 350ohms. I swapped sides and also did an oil change. I used 10w40 this time to see if im having oil pressure issues. went for another 15-20 miles drive and no codes and no misses and seem to have power back.

I think I am going to leave it alone for now and the next oil change I am going to go back to 5w20 and hook up an oil pressure gauge and see where I am at.

 

Most likely that is what it is is an oil pressure issue if the code does not come back after switching to 10W-40. Probably a failing timing chain tensioner gasket. Ford specifies 25 PSI at hot idle which is what my '07 5.4L has as well at hot idle. If yours has only like 20 or below, that can cause an issue.

 

I had this issue as well in my '04. Same exact codes and everything. Did you have any rumbling or rough idling issues?

I did and it was sporadic and Only when the engine was hot. I thought it was the phasers as well but when we pulled the valve covers off there was sludge all throughout the engine as well as scoring. So my engine was shot. If you have time, you might wanna do a good inspection before driving too much further. Just my 2 cents...
