Toyota Allion Oxygen O2 Sensor

Genuine Re-conditioned Oxygen Sensors for All Toyota Allion Models – Directly Imported from Japan

For Toyota Allion owners in Sri Lanka, maintaining peak engine efficiency and emission control depends on the precision of the oxygen (O₂) sensor—commonly known as the lambda sensor. This critical component feeds real-time exhaust oxygen data to the Engine Control Unit (ECU), enabling it to maintain the ideal stoichiometric air-fuel ratio of 14.7:1. The result is optimal combustion, maximum fuel efficiency, and compliance with emission regulations.

Over time, oxygen sensors suffer degradation from carbon fouling, lead or silicone contamination, and thermal cycling. A failing sensor transmits inaccurate voltage signals, causing the ECU to deliver an excessively rich or lean mixture—leading to higher fuel consumption, elevated emissions, and reduced engine performance.

We supply genuine, professionally re-conditioned OEM oxygen sensors for every Toyota Allion model currently on Sri Lankan roads. All units are sourced from Japan and restored to exact manufacturer specifications through advanced cleaning, recalibration, and signal-response testing.

Symptoms of a Defective Oxygen Sensor

Malfunction Indicator Lamp (Check Engine Light) with codes such as P0130–P0167

Drop in kilometres per litre (KPL) efficiency

Rough idle or hesitation under load

Elevated CO and HC readings in emissions testing

Persistent rich exhaust odour

Operating with a failed O₂ sensor for prolonged periods risks damaging the catalytic converter and increases operating costs.
