Toyota Mark 2 Oxygen O2 Sensor

Re-conditioned Oxygen Sensors for Toyota Mark II – Imported from Japan

For Toyota Mark II owners in Sri Lanka, the oxygen (O₂) sensor—also known as the lambda sensor—is a vital component for engine efficiency and emission control. It measures the oxygen content in the exhaust gases and sends signals to the Engine Control Unit (ECU). This allows the ECU to fine-tune the air-fuel mixture, ensuring smooth engine operation, better fuel economy, and reduced exhaust emissions.

With time, oxygen sensors can deteriorate due to constant heat, carbon buildup, and fuel additives. A faulty sensor may transmit inaccurate readings, causing the engine to run rich or lean. This leads to lower fuel efficiency, rough idling, loss of power, and increased emissions.

We supply genuine re-conditioned Japanese oxygen sensors for all Toyota Mark II models in Sri Lanka. Each sensor is carefully restored to factory standards through cleaning, recalibration, and response testing, guaranteeing reliable performance and durability.

Available Toyota Mark II Oxygen Sensor Part Numbers:

JZX110: 89465-22270

MCV20, MCV21, MCV25: 89465-35670

Whichever Mark II variant you own, the correct sensor is available and ready for installation in Sri Lanka.

Signs of a Faulty Oxygen Sensor:

Check Engine Light with fault codes (P0130–P0167)

Drop in kilometres per litre (KPL)

Rough idle or hesitation when accelerating

Higher CO and HC emissions

Noticeable fuel-rich exhaust smell

Driving for long periods with a malfunctioning sensor can damage the catalytic converter and lead to costly repairs.
