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 on scan tool, if applicable. This creates an electronic copy of data taken when fault occurred. Information is then stored in the scan tool for later reference.
3 - This step determines whether DTC P0335 is the result of a hard failure or an intermittent condition. If engine will not start, crank engine over 3 consecutive ignition cycles (key ON - key OFF).
5 - This step verifies internal resistance of the CKP sensor. A typical value at 74°F (23°C) is 2.1 k/ohms.
6 - This step tests CKP sensor output signal and electrical circuit to PCM.
7 - This step determines which half of CKP sensor circuit is faulty.
11 - This step inspects for a faulty signal rotor. Visually check the teeth of the signal rotor through CKP sensor aperture for damage, foreign material, and mis-alignment.
