Lexus GS Air Fuel Ratio Sensor

Genuine Re-conditioned Air Fuel Ratio Sensors for All Lexus GS Series Models – Imported from Japan

For Lexus GS Series owners in Sri Lanka, maintaining peak performance, fuel efficiency, and low emissions relies heavily on the accuracy of the Air Fuel Ratio (AFR) sensor—often called the wideband O₂ sensor. Unlike standard oxygen sensors, AFR sensors deliver highly precise, real-time air-to-fuel ratio data to the Engine Control Unit (ECU). This allows the ECU to finely adjust fuel delivery and ignition timing for flawless combustion, strong performance, and compliance with stringent emission standards.

Over time, AFR sensors can deteriorate due to carbon buildup, contamination from fuel additives, or exposure to extreme exhaust heat. A faulty AFR sensor sends incorrect readings to the ECU, which can cause an overly rich or lean fuel mixture. This may lead to reduced kilometres per litre (KPL), higher emissions, sluggish acceleration, and the Check Engine Light turning on.

We supply genuine, professionally re-conditioned OEM AFR sensors for all Lexus GS Series models on Sri Lankan roads. Every sensor is imported directly from Japan and restored to exact manufacturer standards using advanced cleaning, recalibration, and performance testing—ensuring OEM-level accuracy and durability.
