Mitsubishi Montero Oxygen O2 Sensor

High-Performance Re-conditioned Oxygen Sensors for Mitsubishi Montero – Direct Import from Japan

For Mitsubishi Montero owners in Sri Lanka, keeping the engine running at peak efficiency is a top priority. One of the most important parts in achieving this is the oxygen (O₂) sensor, also known as a lambda sensor. It continuously measures oxygen levels in the exhaust stream and relays this information to the Engine Control Unit (ECU). The ECU then adjusts the air-fuel mixture to deliver smooth driving, improved kilometres per litre (KPL), and cleaner emissions.

Like all engine components, oxygen sensors wear out with time. High exhaust temperatures, carbon deposits, and impurities in fuel can cause inaccurate readings. When the sensor fails, the engine may run too rich or too lean, leading to poor fuel economy, unstable idle, loss of power during acceleration, and excessive exhaust emissions.

We provide carefully re-conditioned Japanese oxygen sensors for Mitsubishi Montero models in Sri Lanka. Each unit undergoes professional cleaning, recalibration, and full performance testing to ensure reliability and durability.

Available Mitsubishi Montero Oxygen Sensor Part Numbers:

MD369189, MR578604 – Montero V65W, V75W
