| Trouble code No_ | Diagnosis item | Description | Major cause | Remarks (Symptoms, etc ) |
|---|---|---|---|---|
| 21 | Engine coolant temperature sensor | (1) Engine coolant terperature sensor signal voltage over 4.6V (2) Engine coolant temperature sensor signal voltage less than 0.11 (3) Engine coolant temperature sensor signal indicates a low engine coolant temperature while the engine is in warmup operation: | (1) Defective engine coolant temperature sensor (2) Open or short circuit in engine coolant temperature sensor circuit; or connector in poor contact (3) Defective engine control unit | With engine cold Poor startability* Unstable idling* Poor acceleration* |
| 22 | Crank angle sensor | (1) Cranking the engine for more than four seconds does not cause the crank angle sensor signal voltage to change (go high or low): (2) Abnormal crank angle sensor signal | Defective crank angle sensor Open or short circuit in crank angle sensor circuit; or con- nector in loose contact (3) Defective cam position sen- sor, or connector in loose contact (4) Defective engine control unit | Engine stalls. Engine cannot be started. |
| 23 | Cam position sensor | (1) Cam position sen- sor signal voltage does not change (go high or low) even with the engine running: (2) Abnormal top dead center signal pat- tern | (1) Defective cam position sen- sor (2) Open or short circuit in cam position sensor circuit; or connector in loose contact (3) Defective crank angle sen- sor, or connector in loose contact (4) Defective engine control unit | Engine stalls |
| 24 | Vehicle speed sensor (reed switch) | With the engine in accelerated operation at an engine speed of over 3,000 rlmin, the vehicle speed sensor signal voltage does not change (go high or low). | (1) Defective vehicle speed sen- sor (2) Open or short circuit in vehi- cle speed sensor circuit; or connector in loose contact Defective engine control unit | When the vehicle is stopped with the engine in decelerated operation, the engine might stall: |
