DTC P0200

DTC P0200 Fuel injector operation identified
• The PCM monitors each cylinder injection confirmation signal from the IDM while the engine is running. If
the PCM does not receive the injection confirmation signal for unspecified cylinder normally, the PCM
determines that the unspecified cylinder fuel injector operation is not verified.
DETECTION
