Multiport Fuel Injection (MFI)

DIAGNOSTIC TROUBLE CODE CHART

WARNING:
When touching the throttle valve, surely shut off the driving circuits of the throttle valve.
In the event that the throttle valve is operated, a finger might be injured as the result of being caught by the throttle valve.

CAUTION:
During diagnosis, a DTC code associated with other system may be set when the ignition switch is turned on with connector(s) disconnected. On completion, confirm all systems for DTC(s). If DTC(s) are set, erase them all.

















NOTE:
Do not replace the engine control module (ECM) until a through terminal check reveals there are no short/open circuits.

NOTE:
Check that the ECM ground circuit is normal before checking for the cause of the problem.

NOTE:
After the ECM detects a malfunction, a diagnostic trouble code is recorded the next time the engine is started and the same malfunction is re-detected. However, for items marked with a "*1", the diagnostic trouble code is recorded on the first detection of the malfunction.

NOTE:
The codes marked with a "*2" in the diagnosis code number column have the following two conditions for recording the diagnostic trouble code.

- In case that the misfire causing the damaged catalyst is detected, the diagnostic trouble code is recorded at the time.
- In case that the misfire deteriorating the exhaust gas is detected, the diagnostic trouble code is recorded when the same malfunction is redetected after the next engine start.
