Caution: Refer to Heated Oxygen Sensor Resistance Learn Reset Caution (See: Powertrain Management/Computers and Control
Systems/Oxygen Sensor/Service Precautions/Heated Oxygen Sensor Resistance Learn Reset Caution).
Note: A new converter with less than 161 km (100 mi) on it may set DTC P0420 or P0430 due to out-gassing of the internal matting.
Operating the vehicle at highway speeds for approximately 1 h may correct the condition.
1. Engine idling, observe the DTC information with a scan tool. Verify there are no HO2S or misfire DTCs set.
瀚慖f any DTCs are set, refer to Diagnostic Trouble Code (DTC) List - Vehicle (See: Diagnostic Trouble Code Descriptions/Diagnostic
Trouble Code (DTC) List - Vehicle) to diagnosis the applicable DTC before proceeding with this diagnostic procedure.
2. Verify the following conditions do not exist with the catalytic converter:
* Dents
* A severe discoloration caused by excessive temperatures
* An internal rattle caused by damaged catalyst substrate
* Restrictions-Refer to Restricted Exhaust (See: Engine, Cooling and Exhaust/Exhaust System/Testing and Inspection/Restricted Exhaust
).
瀚慖f a condition is found, replace the catalytic converter.
3. Verify the following conditions do not exist with the exhaust system:
* Leaks-Refer to Exhaust Leakage (See: Engine, Cooling and Exhaust/Exhaust System/Testing and Inspection/Exhaust Leakage).
* Physical damage
* Loose or missing hardware
* Improperly torqued HO2S
瀚慖f a condition is found, repair the exhaust system.
4. Verify the following conditions do not exist with the HO2S 2:
* A grounded wiring harness
* Damage
瀚慖f a condition is found, replace the HO2S 2.
5. If no physical condition is detected and the HO2S 2 is as active as the HO2S 1 after operating the engine at 1,500 RPM for 1 min and then
returning to a stabilized idle, then replace the catalytic converter.
Repair Instructions
Note: A new converter with less than 161 km (100 mi) on it may set DTC P0420 or P0430 due to out-gassing of the internal matting. Operating
the vehicle at highway speeds for approximately 1 hour may correct the condition.

Repair Verification
1. Verify that no other DTCs are set.
瀚慖f any DTCs are set, refer to Diagnostic Trouble Code (DTC) List - Vehicle (See: Diagnostic Trouble Code Descriptions/Diagnostic
Trouble Code (DTC) List - Vehicle).
2. Operate the vehicle within the Conditions for Running the DTC while observing the scan tool Catalyst Monitor Not At Idle Test Conditions
Met parameter. The parameter will change to Yes when the OFF Idle Conditions have been met.
瀚慖f not the specified value, operate the vehicle within the OFF Idle Conditions.
