Nissan Grand Livina O2 Sensor Malaysia
Grand Livina has upstream (air-fuel ratio sensor pre-cat) and downstream (post-cat catalyst monitor) O2 sensors. Common failures: P0135 or P0141 (sensor heater circuit), P0420 (catalyst efficiency below threshold — downstream sensor or weak catalyst). Malaysia's RON95 fuel quality can cause faster sensor deposit buildup. O2 sensor replacement: upstream sensor is the more critical one — affects fuel economy and emissions. Use OEM or Denso equivalent for reliable readings.

Grand Livina Oxygen Sensor
- Upstream and downstream O2 sensors control fuel trim — replace if reading erratically
- Typical lifespan: 80,000–120,000 km
- Use Denso or NGK OEM-spec replacement sensors
- Bad O2 sensor: rich running, high fuel consumption, occasional misfires, CEL P0130–P0167
