Re: Cam Angle stuck at negative
Look at the CMP A (intake cam sensor) and the associated wiring, this is your non-fixed cam position pickup, which detects cam angle...VTC. Being you didn't mention opening the motor, chances are it's not the VTC gear or the pulseplate. Could be, but my bet is on wiring/sensor.
