Perodua Axia O2 Sensor Malaysia
Single upstream lambda sensor on the EJ-VE — typically lasts 100,000 km or more. Failing sensor causes poor fuel economy and P0136/P0141 codes; RON95 is fine for sensor longevity.
Axia O2 Sensor
- 1KR-FE: upstream and downstream O2 sensors — lifespan 80,000–120,000 km
- Faulty sensor causes rich/lean fuelling, higher emissions, poor fuel economy
- Replace on fault code or noticeable fuel economy drop — do not delay
