Diagnostic Aids

Code P0341 indicates an intermittent fault and may not set immediately or under all conditions. Customer comments of symptom experienced may assist in isolating cause of condition. A poor connection of fault in camshaft position sensor circuits, or a faulty camshaft position sensor, may cause PCM to reinitialize injector sequence when fault occurs, causing a possible stumble or miss.

A poor connection or fault in fuel control circuit, crankshaft position sensor circuits, 18X portion of crankshaft position sensor, or damaged vanes on harmonic balancer interrupter rings will cause PCM to stop pulsing injectors when fault occurs, causing an intermittent stumble or stall.
