Conditions for Clearing the DTC

WARNING: This page is about a different car, the 2016 GMC Acadia, 2016 Chevrolet Traverse, and 2016 Buick Enclave. However, it is still accessible from the selected car via links, so may be relevant.

The current DTC will clear and set to history, when the MSM sees the analog input from the sensor as between 0.22-4.75 volts and the ignition is cycled OFF then back to ACC or RUN.
The history DTC will clear after 50 consecutive fault-free ignition cycles have occurred.
