I have a 2009 Sebring with the 2.4 vvt engine in it. Car has about 150k on it right now. Car recently started over heating and had all the bad signs of a head gasket. So I put a new head gasket and water pump on it this week. I'm getting error code p0340. Sensor test ok. Swapped locations just to double check. Code does not follow sensor. Does anyone have a actual schematic for the engine wiring ? I can find everything else but for the actual engine to pcm schematic. Code has been stored and has been logged before I did head gasket so I'm assuming that the issue is in the harness or pcm and not related to removing the camshafts for head gasket. And phaser or sensor to camshaft interaction would not cause me to loose my reference signal to pcm would it ? Reference voltage and sensor ground are fine. Just seeing that reference voltage on the front intake side cam sensor. Anyone have any in depth knowledge on these particular situations. I know it's a hall effect pull down voltage but it looks like several sensors share common grounds and signals. Don't want to cut open the whole harness if I don't have to.
thanks
