Conditions for Setting the DTC: Notes
WARNING: This page is about a different car, the 2010 Pontiac G5 and 2010 Chevrolet Cobalt. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
The ECM detects engine movement by sensing the airflow through the mass air flow (MAF) sensor when it is more than 3 g/s, or by sensing camshaft position sensor pulses.
