Toyota Prado Oxygen O2 Sensor

Genuine Re-conditioned Oxygen Sensors for Toyota Prado – Imported from Japan

For Toyota Prado owners in Sri Lanka, the oxygen (O₂) sensor—also called the lambda sensor—is essential for maintaining engine efficiency and reducing emissions. It monitors the oxygen content in the exhaust and provides precise feedback to the Engine Control Unit (ECU). This allows the ECU to maintain the correct air-fuel ratio, ensuring smooth combustion, better fuel economy, and lower harmful emissions.

Over time, oxygen sensors wear out due to carbon deposits, fuel additives, and heat exposure. A failing sensor sends inaccurate voltage signals, causing the ECU to run the engine too rich or too lean. This leads to reduced fuel efficiency, sluggish performance, and higher exhaust emissions.

We supply genuine re-conditioned Japanese oxygen sensors for all Toyota Prado GRJ120-series models in Sri Lanka. Each sensor is professionally restored to meet factory specifications through cleaning, recalibration, and signal-response testing, guaranteeing reliable performance.

Available Toyota Prado Oxygen Sensor Part Numbers:

GRJ120, GRJ121, GRJ125: 89465-35670

No matter which Prado variant you drive, the correct sensor is in stock and ready for quick installation in Sri Lanka.

Common Signs of a Faulty Oxygen Sensor:

Check Engine Light with fault codes (P0130–P0167)

Decreased kilometres per litre (KPL)

Rough idle or hesitation under load

Increased CO and HC emissions

Strong fuel-rich exhaust odor

Running the vehicle with a defective sensor for long periods can damage the catalytic converter and increase repair costs.
