Diagnostic Aids
WARNING: This page is about a different car, the 2004 Buick Rendezvous. However, it is still accessible from the selected car via links, so may be relevant.
- Inspect the IMRC solenoid valve for witness marks that indicate that the valve was hitting the intake manifold. This condition may be temperature related.
- A condition with the IMRC driver module, the wiring from the module to the IMRC solenoid, or the solenoid itself will not set a DTC.
