Conditions For Clearing DTC P0717
WARNING: This page is about a different car, the 2002 GMC Cab & Chassis Sierra and 2002 Chevrolet Cab & Chassis Silverado. However, it is still accessible from the selected car via links, so may be relevant.
DTC will clear under the following conditions:
- For California emissions, the PCM turns off the MIL during the third consecutive trip in which the diagnostic test runs and passes.
- A scan tool can clear the DTC.
- For California emissions, the PCM clears the DTC from PCM history if the vehicle completes 40 warm-up cycles without an emission related diagnostic fault occurring.
- For Federal emissions, the PCM clears the DTC from PCM history if the vehicle completes 40 warm-up cycles without a non-emission related diagnostic fault occurring.
- The PCM cancels the DTC default actions when the fault no longer exists, and the ignition is off long enough to power down the PCM.
