DTC P0200

Fuel injector circuit malfunction

DETECTION CONDITION

• PCM monitors injection confirmation signal from IDM while engine is running. If injection confirmation signal is not input normally, PCM determines fuel injector circuit malfunction.

POSSIBLE CAUSE

• IDM

• Short to GND in wiring between IDM terminal 2B and PCM terminal 30
• Short to GND in wiring between IDM terminal 2C and PCM terminal 42
• Short to GND in wiring between IDM terminal 2D and PCM terminal 44
• Short to GND in wiring between IDM terminal 2E and PCM terminal 45
• Short to GND in wiring between IDM terminal 2F and PCM terminal 43
• Short to power circuit in wiring between IDM terminal 2B and PCM terminal 30
• Short to power circuit in wiring between IDM terminal 2C and PCM terminal 42
• Short to power circuit in wiring between IDM terminal 2D and PCM terminal 44
• Short to power circuit in wiring between IDM terminal 2E and PCM terminal 45
• Short to power circuit in wiring between IDM terminal 2F and PCM terminal 43
• Open circuit in wiring between IDM terminal 2B and PCM terminal 30
• Open circuit in wiring between IDM terminal 2C and PCM terminal 42
• Open circuit in wiring between IDM terminal 2D and PCM terminal 44
• Open circuit in wiring between IDM terminal 2E and PCM terminal 45
• Open circuit in wiring between IDM terminal 2F and PCM terminal 43
• PCM malfunction
