P0012 CEL and OIL LIGHT ON

9 | Add Comment Possible causes
- Dirty or low engine oil
- Faulty variable valve timing (VVT)
- Faulty oil control valve (OCV)
- Variable Valve Timing (VVT) harness is open or shorted
- Oil Control Valve (OCV) harness circuit is open or shorted
- Damaged ECM
This could also be the cause of it jumping a tooth on the timing, worn oil pump or the oil deposits are causing blockage from not changing the oil. How many miles are on the engine?

well that motor has about 100k we changed the oil pump a few months ago because the oil light came on and had no oil pressure
after the new pump everything was good until now the oil pressure lights back on
we swapped the motor for a new one
went to crank it and it wont turn over it started to one of the new spark plugs fired but thats it
the crank wont make a full turn when using a ratchet
