2003 Pontiac Bonneville Engine Stalls with P0204 OBD2 Code - Diagnosis and Fixes

Model: 2003 Pontiac Bonneville Fault Code: P0204 Posted: 2015-12-27 17:26

I own a 2003 Pontiac Bonneville that suddenly begins stalling without any warning. The vehicle restarts after shutdown, but the check engine light is on with code P0204. I've already replaced the spark plugs, ignition wires, ignition control module, and oxygen sensor. Despite these repairs, the issue persists. What could be causing this? Is it a faulty fuel injector losing 12V power or an open circuit in the injector wiring?

The P0204 code indicates a potential fault with Injector No. 4, specifically related to loss of 12V power or an open circuit. Possible causes include a faulty remote starter (if equipped), a defective ignition switch, or damaged wiring harness connecting to the fuel injector.
