Symptoms: Rough idle, engine light-solid on from start then blinks after a few minutes. VSC light on, Trac Off Light on, occasional Oil Light upon pressing accelerator with little power and or slight decrease in RPMs(Oil Level is okay). A whiny sound is present at first but then fades as the computer tries to correct the timing/misfire issues. Codes: P0345,300,302,304,306 found. no O2 codes but car has not moved for a few months (no money to fix the car at the time) but was started frequently. The car initially stalled on the highway and had a rough Idle that day.
Cam sensor bank A is okay, but replaced anyway.. Spark plugs have been replaced with OEM plugs.
PCV was replaced seven months ago.. Bank A VVT has been inspected and cleaned but knowing solenoids, there should be more of a snap sound.. Bank A O2 coil checked and found to be okay although if it was not the code would have flagged right away...
Not sure where to look next or what could be causing the problem on just one side of the engine…
Your help is appreciated...
Just tested the voltage that should be at the connector to the Cam Position Sensor and there is no voltage of any kind when the ignition is on or even started. I assumed there should be some kind of voltage at the connector (guessing maximum 12 volts). plugging the sensor in while the engine was on had no affect on the engine in any way. I assume there should have been a change in engine operation...
It is only a two wire connector: Blue wire and a black wire with a white stripe.. doing a continuity test determined that the blue wire is ground and the black wire with white stripe is the signal wire. it is obvious that the blue wire through the connector has continuity to battery ground. there is 24K across the two connector pins which suggests the signal wire is connected to something.
Should there be a voltage at the connector to the Cam Position Sensor?
