Diagnostic Aids
WARNING: This page is about a different car, the 2009 Saturn Vue. However, it is still accessible from the selected car via links, so may be relevant.
- Inspect the ignition coils for aftermarket devices. An aftermarket device connected to the ignition coil circuits may cause this DTC to set.
- If the condition is intermittent move the related harnesses and connectors, with the engine operating, while monitoring the appropriate scan tool Misfire Current Cylinder parameter. This may help isolate the condition.
