P0335 Pontiac -

Question

I have a Oldsmobile Intrigue Which isn't under this site so I had to pick something else similar. Out of nowhere my car wouldn't start. It is married with three codes. Camshaft position sensor 'A' circuit malfunction, Crankshaft position sensor 'A' circuit malfunction and Crankshaft position sensor 'B' circuit malfunction. I assume that a connector or something electrical is at fault considering the unlikeliness that both sensors went simultaneously. I have 190K on it and never changed the Cam sensor. Changed it. The problem went then came back. It now intermittently Can you point me in a direction to go?

Answer 1

P0335 Crankshaft position sensor "A" circuit malfunction

P0340 Camshaft position sensor circuit malfunction

The crankshaft position sensor is actually 2 sensor within a single housing, The PCM uses  cranksensor A. If Cranksensor B is shown you have a circuit problem , you will need to check the harness with key on engine of for its 12 volt refference.at the crank sensor and cam position sensor. a lack of the 12 volt refference is a failed PCM.
