Diagnostic Aids

WARNING: This page is about a different car, the 2009 GMC Sierra and 2009 Chevrolet Silverado. However, it is still accessible from the selected car via links, so may be relevant.

Any condition that causes the engine to stall and/or not start may set this DTC. Possible conditions include:

Fuel conditions such as low level, low pressure, or contamination.
Engine conditions such as low compression.
Restricted exhaust or air intake systems.

Always inspect for DTCs that would cause an engine stall and/or no start condition. Because the hybrid system can rotate the engine at high RPM, stall and cranks-but-does-not-start conditions act differently than a non-hybrid vehicle. Refer to Action Taken When the DTC Sets .
