Nissan/Nissan Serena/O2 Sensor

2026-10-08 · 5 min read

Nissan Serena O2 Sensor Malaysia

Serena MR20DD: upstream wideband lambda sensor and downstream catalyst monitor. Upstream critical for GDI fuel management — OEM quality recommended, aftermarket may cause fuel trim issues. Common codes: P0135 (heater), P0420 (catalyst). RON95 use accelerates upstream sensor fouling. Inspect at 80,000 km.

Serena Oxygen Sensor

MR20DD S-Hybrid: upstream and downstream O2 sensors both active
Failing O2 sensor causes rich/lean running — fuel economy drops noticeably
P0133 slow upstream response, P0137 downstream voltage low = sensor replacement needed
Denso or NGK OEM-spec sensors — ensure thread pitch matches MR20DD spec
