DTC P0133:00 DTC P0153:00 |
P0133:00: A/F sensor (RH) circuit slow response P0153:00: A/F sensor (LH) circuit slow response |
---|---|
DETECTION CONDITION
|
• P0133:00 indicates slow response of A/F sensor (RH) circuit
• P0153:00 indicates slow response of A/F sensor (LH) circuit
• The PCM monitors oxygen sensor response time by commanding a calibrated fuel control routine. This routine sets the air fuel ratio to a calibrated limit to produce a predictable oxygen sensor signal amplitude. For vehicles with universal heated oxygen sensors (HO2S), the test fails if the oxygen sensor signal does not reach the predicted amplitude within a predetermined response time. For vehicles with heated oxygen sensors (HO2S), the test fails when the oxygen sensor amplitude is less than the predicted minimum amplitude limit.

POSSIBLE CAUSE
|
• Contaminated A/F sensor
• Incorrect fueling
• MAF sensor malfunction
• Exhaust leaks
• Open or short circuit between PCM and A/F sensor
• Inlet air leaks
• Deteriorating A/F sensor
• A/F sensor heater malfunction
• PCM malfunction

STEP |
INSPECTION |
ACTION |
|
---|---|---|---|
1
|
VERIFY FREEZE FRAME DATA HAS BEEN RECORDED
• Has FREEZE FRAME DATA been recorded?
|
Yes
|
Go to the next step.
|
No
|
Record FREEZE FRAME DATA on the repair order, then go to the next step.

2
|
VERIFY RELATED SERVICE INFORMATION AVAILABILITY
• Verify related Service Information availability.
• Is any related Service Information available?
|
Yes
|
Perform repair or diagnosis according to the available Service Information.
• If the vehicle is not repaired, go to the next step.
|
No
|
Go to the next step.
|
||
3
|
PERFORM KOER SELF-TEST
• Verify that the engine is at normal operating temperature.
• Perform the KOER self-test.
• Are any DTCs present other than P0133:00 or P0153:00?
|
Yes
|
Go to the appropriate DTC troubleshooting.
|
No
|
Go to the next step.
|

4
|
INSPECT FOR SOURCE OF POTENTIAL A/F SENSOR CONTAMINATION
• Investigate the following items as potential sources of A/F sensor contamination:
• Is a concern present?
|
Yes
|
Repair the source of the contamination. Change the engine oil and oil filter. Then go to Step 6.
|
No
|
Go to the next step.
|
||
5
|
VERIFY A/F SENSOR RESPONSE TEST RESULTS
• Access the DIAGNOSTIC MONITORING TEST RESULTS for the O2S11 and O2S21
• Is the indicated value greater than the minimum threshold?
|
Yes
|
Unable to duplicate or identify the concern at this time.
|
No
|
Replace the suspect A/F sensor.
Then go to the next step.

6
|
VERIFY TROUBLESHOOTING OF DTC P0133:00, P0153:00 HAS BEEN COMPLETED
• Verify that all disconnected connectors are reconnected.
• Clear the DTC from the PCM memory using the M-MDS.
• Perform the OBD DRIVE MODE up to HO2S (Step 5).
• Retrieve DTCs using the M-MDS.
• Is the PENDING CODE for this DTC present?
|
Yes
|
Repeat the inspection from Step 1.
• If the malfunction recurs, replace the PCM.
Go to the next step.
|
No
|
Go to the next step.

7
|
VERIFY AFTER REPAIR PROCEDURE
• Perform the “AFTER REPAIR PROCEDURE”.
• Are any DTCs present?
|
Yes
|
Go to the applicable DTC inspection.
|
No
|
Troubleshooting completed.
