Component Inspection
■ Check HO2S
1.

Visually/physically inspect the following conditions:

- Ensure that the sensor is securely installed

- Check for corrosion on terminals

- Check for damaged wiring

- Repair as necessary and go to next step

2.

Warm up the engine to normal operating temperature and let it idle

3.

Connect GDS and monitor the O2 SNSR VOL.-B1/S2 parameter on the GDS data list.

Specification : Above 0.6V at idle

4.

Is sensor data near the specified value?

▶ Check for poor connection between PCM/ECM and component: backed out terminal, improper mating, broken locks or poor terminal to wire connection. Repair as necessary and go to "Verification of Vehicle Repair" procedure.

▶ Check HO2S for contamination, deterioration, or damage. Substitute with a known-good HO2S and check for proper operation. If the problem is corrected, replace HO2S and then go to "Verification of Vehicle Repair" procedure.
