Sub-Oxygen Sensor Heater
- Electrical connector for sub-oxygen is located on passenger's side of console, just below shift lever, beneath the carpet. Disconnect electrical connector from sub-oxygen sensor and note sub-oxygen sensor terminals. See Fig 1.
- Using ohmmeter, measure resistance between sub-oxygen sensor terminals +B and HT. See Fig 1. Replace sub-oxygen sensor if resistance is not 11-16 ohms at 68°F (20°C).
