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.
- Turn ignition switch ON.
- Turn ignition switch OFF and wait at least 10 seconds.
- Start 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 conditions.
DTC ECM Condition Voltage Connector + - Terminal Terminal P0138 F8 57 [HO2S2 (bank 1) signal] 59 (Sensor ground) Revving up to 4, 000 rpm under no load at least 10 times The voltage should be below 0.18 V at least once during this procedure. P0158 58 [HO2S2 (bank 2) signal] 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 conditions.
DTC ECM Condition Voltage Connector + - Terminal Terminal P0138 F8 57 [HO2S2 (bank 1) signal] 59 (Sensor ground) Keeping engine speed at idle for 10 minutes The voltage should be below 0.18 V at least once during this procedure. P0158 58 [HO2S2 (bank 2) signal] 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 conditions.
DTC ECM Condition Voltage Connector + - Terminal Terminal P0138 F8 57 [HO2S2 (bank 1) signal] 59 (Sensor ground) Coasting from 80 km/h (50 MPH) with selector lever in the D position The voltage should be below 0.18 V at least once during this procedure. P0158 58 [HO2S2 (bank 2) signal] Is the inspection result normal?
YES: INSPECTION END
NO: Proceed to "DIAGNOSIS PROCEDURE ".
