I got a code of p0012 tonite at the track and car runs like ass. What would cause this the car only has 45000 miles on it so I dought it jumped timing a bad cam sensor or phaser maybe it says that the timing is to far retarded. Any help would be greatly apreciated. I did a search and found next to nothing.

owie

how long the cams been installed?

i installed my cams myself and did copious research on what could go wrong, including any related DTC's i might need to watch out for, and that is shorely one of them; sounds like you (or installer) let the timing chain slack and jump a tooth during the install. being the camshat timing is variable (VCT), i don't know how long it would take the car to realize it's off a tooth.. 1 tooth is only 17 degrees timing, and the phaser can eat up a bunch more than 17 degrees..

the cam is off time on one side.

maybe you were runnin the piss out of it and managed to get the chain to jump a tooth, but i vote this is less than 1% likely; hydraulic chain tensioner, etc..

i didn't design the motor, so i don't know how much timing she'll give and take under various circumstances, but i can tell you if i got that code, i'd be right back under those cam covers/front cover retiming that motor.. cause you shorely don't want valve-to-piston contact right?

i know we (Ford) has a vehicle called a CX-7 (mazda.) it's a turbo'ed 4 cylinder, that's mated to a 6spd automatic trans only. it was geared to a bit of a strange crowd (typically single females that have decent jobs drive this car), considering the performance aspect (turbo.) well, this strange crowd are the kind of people that tend not to wind out the gears (don't accelerate fast enough,) which causes the trans to shift early, and the end result is the engine spends a considerable amount of time at lower RPM's. well because it's a turbo, it's got a bit of a mild cam in it, for being a stock car. and because these morons spend so much time at low RPM, the cam bucks (which i'm sure you've experienced on your FRPP's.. i know i have) and actually stretches the chain.

so, i haven't seen a spec for chain stretch, but i'd certainly pull it down and check for wear/tear/damage/timing.

I strongly dought it is the cam install as I have had them in for a year and half with out any problem. The car only made three passes and I shift at 6000 so I know I'm not over reving her. I strongly don't think it jumped time as I have the valve covers off now and the chains are tight so no tensioner issues. The phaser on the drivers side is more unwound than the passenger side but the still pins are still intact that hold the phaser spring from unravling. I'm still lost at this point I will post pics of phasers momentarilly and maybe some one can tell that has phaser issues in the past. I noticed on some truck sites that the vct scylinoid tends to be the culprit some times. Keep bringing on the ideas to help me out and I will keep y'all informed on the out come incase any one else runs in to this problem.

Is it just me or does the phaser in Pic 4 look screwed?


it does. When I was on my first rebuild we had the phasers out and all good till one of the guys miss-handled or bumpted it and it looks twisted like that. I think it was 54 bucks for a new one.. its been a while

So if the phaser fails will it cause that code to show UPI thought that might be it but I have never seen the cam covers off so I wasn't sure what the phasers look like is it better to replace both or do I need to just replace that one

Well if the driverside is bad the code is for bank 1 camshaft A ithought bank 1 was the passenger side so I guess I'll replace both of them.
