Conditions for Setting the DTC

WARNING: This page is about a different car, the 2006 Pontiac Montana SV6, 2006 Chevrolet Uplander, and 2006 Buick Terraza. However, it is still accessible from the selected car via links, so may be relevant.

The difference between the actual idle RPM and the desired idle RPM exceeds a calibrated limit. This limit varies from 300 RPM at -40°C (-40°F) to 175 RPM at 152°C (305°F) based on engine coolant temperature.
The above condition must be present for 8 seconds in order for the test to fail. Four tests must fail in order to set this DTC. The vehicle must exit Conditions for Running between each test.
