Conditions for Clearing the DTC

WARNING: This page does not describe the selected car, but rather 8 other vehicles, including the 2007 GMC Yukon XL, 2007 GMC Yukon, 2007 Chevrolet Tahoe, 2007 Chevrolet Suburban, and 2007 Chevrolet Avalanche. 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 0.27-4.65 volts and the ignition is cycled OFF then back to ACC or RUN.
A history DTC will clear after 50 ignition cycles or with a scan tool using the clear DTCs function.
