So, i replaced both cam sensors, the crank sensor, changed the oil and filter, and the crankcase is full of oil. i logged data with cipher and bank 1 is not advancing like it is supposed to with throttle. bank 2 is advancing with throttle. both variable timing solenoids are getting power from the ecu, as i logged the solenoid % as well. in addition, both solenoids are brand new. car throws a regular p0011 and is definitely low on power, especially in the midrange.

i have not cleaned the maf sensor yet, but it looked clean. is it worth cleaning it? the next thing i can think of is replacing the vtc pulley, but that is not an easy job with the engine in the car. is there any way i can verify to make sure that is the problem before i dive into a job like that and do that much work?

 

bump, or does anyone have any other ideas as far as simple things to check?
thanks

 

this might be for a different problem, but did you check the oil squirter hole?

 

which oil squirter hole are you talking about? there are quite a few it seems that are involved with the variable timing, thanks for the reply

 

I take back my last suggestion about the oil squirter - it was late and I wasn't thinking straight - however, I if you have eliminated the possibility of this being a problem with either the cam shaft position sensors or crankshaft position sensor, I would take a very close look at the signal pickup portion of the camshaft(s). Sometime an accumulation of debris can cause this problem when it blocks the signal.

 

I suppose it's possible the flywheel could be damaged too, causing a similar problem, but it that case you may even have problems getting the car to start.

 

i somewhat checked this. when i had the cam sensors out, i stuck my finder in the cam sensor location and tried to see if i felt anything on that part of the cams. i didnt feel anything, but not exactly a foolproof test either. both cam sensors were clean with no debris at all on them.

 

i am an auto, so i have a flexplate. the car was recently being worked on and the work involved the tranmission being removed. i am pretty sure they had the flexplate off as well to repair some leaks, so this had crossed my mind. however, if it was a flexplate issue, i would think there would be the crank sensor code (p0335) and/or the problem would not be limited to bank 1 only. thoughts?

 

Was this problem ever resolved? I'm having the same issue. Thank you.

 

I believe he fixed it by swapping out the VTC pulley inside the timing.

 

What do you mean the vvt cam sprocket pulley?

 

Cam sprockets, on VVT engines they're a pretty complicated piece that allows the actuator solenoid to advance the cams, they're about $300 apiece.

Not technically a "pulley".

There are a lot of potential causes of the P0011/P0021 codes depending on exactly which motor you have so I definitely don't recommend just throwing parts at it because each bank has nearly $1000 worth of stuff that could "potentially" be wrong. Troubleshoot...
