camshaft sensor
« on: 11 March 2012, 22:23:11 »
Hi all,
I have just done a cylinder head gasket on my 2.2  When it came to start the engine, it would not fire up. The only fault that registered was for the cam-sensor.
Do camshaft sensors just check for rotation of the camshafts or do they check that the timing is ok?

I maybe wrong I'm not overly familiar with the 2.2 but I think the ecu uses the cam sensor to fire the injectors during start up. I know the v6 will run with it unplugged but not start.

Will run on just crank sensor but will be a bugger to start and will run in limp mode.

Today i fitted a new cam sensor but the car does not start.  Traced the wiring back to the ECU and found no breaks in the wires.

Hi all,

I used a genuine GM sensor, and still got p0340 fault code, no other codes listed.
