Component Function Check
- PERFORM COMPONENT FUNCTION CHECK-I
Without CONSULT
- Start engine and warm it up to the normal operating temperature.
- Turn ignition switch OFF and wait at least 10 seconds.
- Restart engine and keep the engine speed between 3, 500 and 4, 000 rpm for at least 1 minute under no load.
- Let engine idle for 1 minute.
- Check the voltage between ECM harness connector terminals under the following condition.
ECM Condition Voltage Connector + - Terminal Terminal F11 50 (HO2S2) 59 Revving up to 3, 600 rpm under no load at least 10 times The voltage should be above 0.78 V at least once during this procedure. Is the inspection result normal?
YES: INSPECTION END
NO: GO TO 2.
- PERFORM COMPONENT FUNCTION CHECK-II
Check the voltage between ECM harness connector terminals under the following condition.
ECM Condition Voltage Connector + - Terminal Terminal F11 50 (HO2S2) 59 Keeping engine at idle for 10 minutes The voltage should be above 0.78 V at least once during this procedure. Is the inspection result normal?
YES: INSPECTION END
NO: GO TO 3.
- PERFORM COMPONENT FUNCTION CHECK-III
Check the voltage between ECM harness connector terminals under the following condition.
| ECM | Condition | Voltage | ||
|---|---|---|---|---|
| Connector | + | - | ||
| Terminal | Terminal | |||
| F11 | 50 (HO2S2) | 59 | Coasting from 80 km/h (50 MPH) in D position (CVT), 4th gear position (M/T) | The voltage should be above 0.78 V at least once during this procedure. |
Is the inspection result normal?
YES: INSPECTION END
NO: Go to "DIAGNOSIS PROCEDURE ".
