WARNING: This page is about a different car, the 2003 Pontiac Vibe. However, it is still accessible from the selected car via links, so may be relevant.
The numbers below refer to the step numbers in the diagnostic procedures.
- 1 - The Diagnostic System Check - Engine Controls prompts the technician to complete some basic checks and store freeze frame data, if applicable. This creates an electronic copy of data taken when fault occurred. The information is then stored in the scan tool for later reference.
- 2 - This step checks whether DTC P1335 is the result of a hard failure or an intermittent condition. If engine will not start, crank engine over for 3 consecutive ignition cycles.
- 3 - This step is checking the internal resistance of the CKP sensor and tests if CKP sensors windings are opened or shorted.
- 4 - Using a DMM, measure resistance of wires between PCM connector to CKP connector. If DMM reads higher than 0.5 ohms, check for a short or high resistance in the circuit. Also, using a test light connected to ground with both PCM and CKP connectors unplugged, probe each connector terminal. This will determine if there is a short to battery voltage.
