P0133-00 (PCM (PYUL)) DIAGNOSTIC PROCEDURE

Step	Inspection	Results	Action
1	PURPOSE: VERIFY A/F SENSOR CONNECTOR FOR MALFUNCTION Inspect the applicable connector and terminal. (See CONNECTOR INSPECTION ) Are the connector and terminal normal?	Yes	Go to the next step.
1		No	Repair or replace the malfunctioning location and perform the repair completion verification 1.
2	PURPOSE: VERIFY A/F SENSOR IS INSTALLED POORLY Verify the A/F sensor installation condition. (Refer to [AIR FUEL RATIO (A/F) SENSOR REMOVAL/INSTALLATION ] in Service Information). Is the installation condition normal?	Yes	Go to the next step.
2		No	Correctly install the A/F sensor and perform the repair completion verification 1. (Refer to [AIR FUEL RATIO (A/F) SENSOR REMOVAL/INSTALLATION ] in Service Information).
3	PURPOSE: VERIFY IF MALFUNCTION RELATED TO EXHAUST SYSTEM AFFECTS A/F SENSOR SIGNAL Inspect for exhaust gas leakage from the exhaust system. (between A/F sensor and HO2S) Is there any malfunction?	Yes	Repair or replace the malfunctioning location and perform the repair completion verification 1.
3		No	Go to the next step.
4	PURPOSE: VERIFY A/F SENSOR FOR MALFUNCTION Inspect the applicable part. (Refer to [AIR FUEL RATIO (A/F) SENSOR INSPECTION ] in Service Information). Is the part normal?	Yes	Go to the next step.
4		No	Repair or replace the malfunctioning location and perform the repair completion verification 1. (Refer to [AIR FUEL RATIO (A/F) SENSOR REMOVAL/INSTALLATION ] in Service Information).
5	PURPOSE: VERIFY A/F SENSOR HEATER FOR MALFUNCTION Inspect the applicable part. (Refer to [AIR FUEL RATIO (A/F) SENSOR INSPECTION ] in Service Information). Is the part normal?	Yes	Go to the next step.
5		No	Repair or replace the malfunctioning location and perform the repair completion verification 1. (Refer to [AIR FUEL RATIO (A/F) SENSOR REMOVAL/INSTALLATION ] in Service Information).
Repair completion verification 1	PURPOSE: VERIFY THAT VEHICLE IS REPAIRED Install/connect the part removed/disconnected during the troubleshooting procedure. Clear the DTC recorded in the memory. (See CLEARING DTC ) Replicate the vehicle conditions at the time the DTC was detected using the following procedure. Implement the repeatability verification procedure. (See Repeatability Verification Procedure ) Perform the DTC inspection for the PCM. (See DTC INSPECTION ) Is the same Pending DTC present?	Yes	Refer to the controller area network (CAN) malfunction diagnosis flow to inspect for a CAN communication error. (See MALFUNCTION DIAGNOSIS FLOW [CONTROLLER AREA NETWORK (CAN)] ) If the CAN communication is normal, perform the diagnosis from Step 1. If the malfunction recurs, replace the PCM. (Refer to [PCM REMOVAL/INSTALLATION ] in Service Information).
Repair completion verification 1		No	DTC troubleshooting completed.
