I've found mixed information, but most things say engine need set #1 at TDC, how do you do this? I've been told it is likely the Cam Sensor Synchronizer. I replaced the sensor and the codes were reset, but the next time I started the car the light came back on with the same code.
I found the sensor (buried beneath the cable bundle), I manager to pry up on the cable bundle w/ a screwdriver just enough to unscrew the two 8mm screws holding in the sensor. I had a code for a bad Camshaft Position Sensor.
