Diagnostic Aids

WARNING: This page does not describe the selected car, but rather 6 other vehicles, including the 2002 GMC Savana Special, 2002 GMC Savana Camper Special, 2002 GMC Savana, 2002 Chevrolet RV Cutaway, and 2002 Chevrolet Cutaway. However, it is still accessible from the selected car via links, so may be relevant.

An intermittent may be caused by the following conditions:

A hard start and a possible poor performance condition might exist. DTC P0216 will possibly set if the injection timing is not set correctly. See INJECTION PUMP TIMING/TDC OFFSET in appropriate ON-VEHICLE ADJUSTMENTS article.

Opens or grounds in any of the circuits may result in full advance and very noisy operation.

Check the Snapshot Data in order to confirm the diagnosis. If the error is less than the Desired Timing, the fault is not the result of a circuit condition. If the error is more than the Desired Timing, check all of the circuits that are related to the Injection Timing Stepper (ITS) motor.
