CHEV SILVER-ADO VORTEX MOTOR V8 PETROL 2002. Runs rough and service light comes on. Showed diagnostic for air flow and cam sensor zeroed codes then ran and cam sensor code is back. It is O.K when cold but stalls and won't start. Where is the cam sensor found?
Thanks: NOEL.

MY SCAN TOOL IS ONE THAT IS CONNECTED TO MY LAP TOP AND IT TELLS ME AIR FLOW CONNECTION FAULT AND CAM SENSOR ELECTRICAL FAULT. AFTER CLEARING THE CODES AND STARTING THE MOTOR THE ENGINE SERVICE LIGHT WAS OFF FOR ABOUT ONE MINUTE AND THEN CAME BACK ON. CHECKED CODES AGAIN AND NOW ONLY CAM SENSOR ELECTRICAL FAULT.

I will check it again I think a number and letter was before the description of what the fault was.I have looked around the bell housing area for a crank sensor and can't find it. I will be in New Zealand next week and may be able to get what I need in Australia or New Zealand. Will read codes this afternoon.
Thanks: NOEL.

Scanned the codes again and it comes up with CODE P1345 SORE DTC Number 1 SGC (Cam Position)SENSOR CIRCUIT MALFUNCTION / CRANKSHAFT POSITION
CAMSHAFT POSITION CORRELATION.
The vehicle is a 350 chev Vortec
VIN 2GEC19R5V1195576 and I think the year should be 1995 not 2002
Thanks for all your assistance so far: NOEL.

Just as I suspected, that is not indicating a malfunction in any component. It's telling you that the Cam sensor is not synched with the Crank sensor and that is because the distributor was installed wrong. You need to use a professional scan tool that had a PID for Cam offset and you need to turn the distributor with the engine running until that PID reads "0" degrees. Then the code will not reset.

That VIN says it's a 97 with a 5.7, made in Canada.

Don't confuse turning that distributor with setting timing. It does not. The timing is predetermined and moving the distributor only takes the primary and secondary ignition out of synch with each other along with the injectors.
