Camaro Pop

Owners of 2010-2014 Chevy Camaro vehicles may comment about an intermittent pop or multiple popping noises from the rear of the vehicle shortly after a cold start or EVAP purge event.

The technician should be able to duplicate the concern by commanding a purge and seal on the EVAP system using GDS2. As the vacuum reaches 3 to 5 inches, the pop noise should be duplicated.

The cause for this concern is the auxiliary fuel module in the left side of the fuel tank changing height (spring loaded leg) as the fuel tank collapses slightly.

Replace the auxiliary fuel module with a newly developed part. The sender kit is available as P/N 13592089.
