DTC DETECTION LOGIC
To judge the malfunction, the diagnosis checks that the A/F signal computed by ECM from the A/F sensor 1
signal is not inordinately high.
DTC CONFIRMATION PROCEDURE
1.
PRECONDITIONING
If DTC Confirmation Procedure has been previously conducted, always perform the following procedure
before conducting the next test.
1. Turn ignition switch OFF and wait at least 10 seconds.
2. Turn ignition switch ON.
3. Turn ignition switch OFF and wait at least 10 seconds.
TESTING CONDITION:
Before performing the following procedure, confirm that battery voltage is more than 10.5 V at idle.
>> GO TO 2.
2.
CHECK A/F SENSOR FUNCTION
1. Start engine and warm it up to normal operating temperature.
2. Select “ENGINE” using CONSULT.
3. Select “A/F SEN1 (B1)” in “DATA MONITOR” mode.
4. Check “A/F SEN1 (B1)” indication.
Is the indication constantly approx. 5 V?
YES
>> Proceed to
.
NO
>> GO TO 3.
3.
PERFORM DTC CONFIRMATION PROCEDURE
1. Turn ignition switch OFF and wait at least 10 seconds and then restart engine.
2. Drive and accelerate vehicle to more than 40 km/h (25 MPH) within 20 seconds after restarting engine.
CAUTION:
Always drive vehicle at a safe speed.
3. Maintain the following conditions for about 20 consecutive seconds.
NOTE:
• Keep the accelerator pedal as steady as possible during the cruising.
• If this procedure is not completed within 1 minute after restarting engine at step 1, return to step
1.
4. Check 1st trip DTC.
Is 1st trip DTC detected?
YES
>> Proceed to
.
NO
>> INSPECTION END
DTC No.

1.
CHECK GROUND CONNECTION
1. Turn ignition switch OFF.
2. Check ground connection E15. Refer to Ground Inspection in
.
Is the inspection result normal?
YES
>> GO TO 2.
NO
>> Repair or replace ground connection.
2.
CHECK AIR FUEL RATIO (A/F) SENSOR 1 POWER SUPPLY CIRCUIT
1. Disconnect A/F sensor 1 harness connector.
2. Turn ignition switch ON.
3. Check the voltage between A/F sensor 1 harness connector and ground.
Is the inspection result normal?
YES
>> GO TO 4.
NO
>> GO TO 3.
3.
DETECT MALFUNCTIONING PART
Check the following.
• IPDM E/R harness connector F42
• 20A fuse (No. 53)
• Harness for open or short between A/F sensor 1 and fuse
>> Repair or replace harness or connectors.
4.
CHECK A/F SENSOR 1 INPUT SIGNAL CIRCUIT FOR OPEN AND SHORT
1. Turn ignition switch OFF.
2. Disconnect ECM harness connector.
3. Check the continuity between A/F sensor 1 harness connector and ECM harness connector.
4. Check the continuity between A/F sensor 1 harness connector and ground or ECM harness connector
and ground.
5. Also check harness for short to power.
