Malfunction Indicator Lamp (MIL)
[EOBD]
A malfunction indicator lamp illuminates to notify the driver that there is a problem with the vehicle. However, the MIL will go off automatically after 3 subsequent sequential driving cycles without the same malfunction. Immediately after the ignition switch is turned on (ON position - do not start), the MIL will illuminate continuously to indicate that the MIL operates normally.
Faults with the following items will illuminate the MIL.
- Catalyst
- Fuel system
- Manifold Absolute Pressure Sensor (MAPS)
- Intake air temperature sensor
- Engine coolant temperature sensor
- ETC module (TPS & ETC motor)
- Heated oxygen sensor (Upstream)
- Heated oxygen sensor heater (Upstream)
- Heated oxygen sensor (Downstream)
- Heated oxygen sensor heater (Downstream)
- Injector
- Misfire
- Crankshaft position sensor
- Camshaft position sensor
- Evaporative emission control system
- Vehicle speed sensor
- Power supply
- ECM/PCM
- MT encoding
- Acceleration sensor
- MIL-ON request signal
- Power stage
[NON-EOBD]
A malfunction indicator lamp illuminates to notify the driver that there is a problem with the vehicle. However, the MIL will go off automatically after 3 subsequent sequential driving cycles without the same malfunction. Immediately after the ignition switch is turned on (ON position - do not start), the MIL will illuminate continuously to indicate that the MIL operates normally.
Faults with the following items will illuminate the MIL
- Heated oxygen sensor (HO2S)
- Manifold Absolute Pressure Sensor (MAPS)
- Engine coolant temperature sensor (ECTS)
- ETC module (TPS & ETC motor)
- Injectors
- ECM
[Inspection]
- After turning ON the ignition key, ensure that the light illuminates for about 5 seconds and then goes out.
- If the light does not illuminate, check for an open circuit in the harness, a blown fuse or a blown bulb.
