NO

>> GO TO 3.

2.

CHECK HEATED OXYGEN SENSOR 2

With CONSULT

1. Turn ignition switch ON and select “DATA MONITOR” mode of “ENGINE” using CONSULT.

4. Start engine and keep the engine speed between 3,500 and 4,000 rpm for at least 1 minute under no load.

5. Let engine idle for 1 minute.

6. Select “FUEL INJECTION” in “ACTIVE TEST” mode of “ENGINE” using CONSULT, and select “HO2S2

(B1)” as the monitor item with CONSULT.

7. Check “HO2S2 (B1)” at idle speed when adjusting “FUEL INJECTION” to 

± 25%.

“HO2S2 (B1)” should be above 0.73 V at least once when the “FUEL INJECTION” is + 25%.

“HO2S2 (B1)” should be below 0.18 V at least once when the “FUEL INJECTION” is 

 25%.

Is the inspection result normal?

YES

>> INSPECTION END

NO

>> GO TO 6.

3.

CHECK HEATED OXYGEN SENSOR 2-1

Without CONSULT

1. Start engine and warm it up to normal operating temperature.

2. Turn ignition switch OFF and wait at least 10 seconds.

3. Start engine and keep the engine speed between 3,500 and 4,000 rpm for at least 1 minute under no load.

4. Let engine idle for 1 minute.

5. Check the voltage between ECM harness connector and ground as per the following condition.

Is the inspection result normal?

YES

>> INSPECTION END

NO

>> GO TO 4.

DTC Description

INFOID:0000000011277994

DTC DETECTION LOGIC

To judge malfunctions, this diagnosis measures response time of the A/F signal computed by ECM from the A/

F sensor 1 signal. The time is compensated by engine operating (speed and load), fuel feedback control con-

stant, and the A/F sensor 1 temperature index. Judgment is based on whether the compensated time (the A/F

signal cycling time index) is inordinately long or not.

POSSIBLE CAUSE

• Harness or connectors (The A/F sensor 1 circuit is open or shorted.)

• A/F sensor 1

FAIL-SAFE
