Hello my name is***** am an ASE Master Technician and I am glad to help you with your question.
Have you changed the engine oil and are you using an aftermarket oil filter?
Do you have the steps from the service manual to diagnose this code?
I can send you the procedures to diagnose this code if you would like.
I have seen issues with clearances in the engine, this causes lower oil pressure on bank 1 because of the way the engine oil pump feeds the engine with oil and the bank 1 cam phaser is farthest away from the oil pump.
I do not see a cat causing the p0012 code.
P0012 - INTAKE CAMSHAFT POSITION TIMING - OVER-RETARDED (BANK 1)
Description: The powertrain control module (PCM) monitors the variable camshaft timing (VCT) position for over-retarded camshaft timing. The test fails when the camshaft timing exceeds a maximum calibrated value or remains in a retarded position.
Diagnostic Aids: This DTC is a functional check of the VCT unit. Diagnose any base engine concerns related to the engine oil pressure or engine timing. Refer to the appropriate ENGINE SYSTEM - GENERAL INFORMATION article .
It would be more likely that the initial timing was not set correctly.
I have never tried that, I prefer to line everything up to the timing marks with the marks on the chains.
The problem is making sure the chain does not move on the crank sprocket, there is a wedge that looks like a cheese wedge that holds the chain on the sprocket.
If you pull the valve covers you may be able to see if the timing marks on the cam phasers are lined up.
That is right. Were you able to make any progress on this?
