On-Board Diagnostics

Fuel Injection Fault Display Unit:

Fuel Injection Fault Display Unit--will display the relevant fault code, in addition to the EFI (Check Engine) warning light being illuminated.

NOTE: Fault code 59 will NOT be indicated by the EFI warning light.

EFI Warning Symbol (Check Engine)--will illuminate when the ECU detects that it cannot maintain correct air/fuel ratio due to a fault in one of the following fuel injection system components:

^ Air Flow Sensor
^ Lambda Sensor
^ Water Temperature Sensor
^ Throttle Position Sensor

The symbol will illuminate on initial turn of the ignition key as part of the bulb check feature, and will go out after a few seconds.

If the symbol illuminates when the engine is idling or the vehicle is being driven, it indicates a failure of one of the four functions. The vehicle should be driven with care, and the cause rectified. Refer to test procedure for the particular functions. Should one of the functions fail, the vehicle can still be driven due to a limp home feature incorporated into the fuel injection system.
