Diagnosis Procedure
INFOID:0000000011277986
1.
CLEAR THE MIXTURE RATIO SELF-LEARNING VALUE
1. Clear the mixture ratio self-learning value. Refer to
.
2. Run engine for at least 10 minutes at idle speed.
Is the 1st trip DTC P0171 detected? Is it difficult to start engine?
YES
>> Perform trouble diagnosis for DTC P0171. Refer to
.
NO
>> GO TO 2.
2.
CHECK HO2S2 GROUND CIRCUIT
1. Turn ignition switch OFF.
2. Disconnect heated oxygen sensor 2 (HO2S2) harness connector.
3. Disconnect ECM harness connector.
4. Check the continuity between HO2S2 harness connector and ECM harness connector.
5. Also check harness for short to power.
Is the inspection result normal?
YES
>> GO TO 3.
NO
>> Repair or replace error-detected parts.
3.
CHECK HO2S2 INPUT SIGNAL CIRCUIT
1. Check the continuity between HO2S2 harness connector and ECM harness connector.
2. Check the continuity between HO2S2 harness connector and ground, or ECM harness connector and
ground.
