Lexus RX350 Oxygen Sensor MCU33/MCU38, GSU30/GSU35 – Genuine Reconditioned O2 Sensor

Lexus RX350 Oxygen Sensor in Sri Lanka

Genuine Japanese Re-Conditioned O2 Sensor

The Lexus RX350 Oxygen Sensor monitors the oxygen level in the exhaust gases and sends accurate feedback to the engine control unit. This helps maintain the correct air-fuel mixture, support smooth engine performance, improve fuel efficiency, and control exhaust emissions.

This genuine Japanese re-conditioned oxygen sensor is suitable for selected Lexus RX350 models, including the MCU33, MCU38, GSU30, GSU35, GGL10, and GGL15 chassis variants. Please confirm the vehicle chassis code, engine specification, sensor position, connector, and original part number before ordering.

A worn or defective oxygen sensor may contribute to a check-engine warning, unstable idling, reduced fuel economy, poor acceleration, or increased emissions. Replacing the sensor with the correct OEM-matching part can help restore reliable exhaust-gas feedback and normal engine-control operation. Lexus lists oxygen sensor part number 89465-0E040 for selected RX350 applications, while parts catalogues identify 89465-08040 and 89465-0E020 for earlier RX350 fitments.

Applications

Replacing a faulty oxygen sensor on selected Lexus RX350 models

Diagnosing check-engine warnings related to oxygen-sensor readings

Addressing poor fuel economy caused by inaccurate exhaust feedback

Supporting smoother idling and more consistent engine response

Restoring oxygen-sensor feedback during emissions-system maintenance

Common Symptoms of a Faulty Oxygen Sensor

Check-engine light or oxygen-sensor-related diagnostic trouble codes

Reduced fuel economy

Rough or unstable idling

Slow throttle response or reduced acceleration

Increased exhaust emissions

Diagnostic codes should be checked before replacement because similar symptoms can also be caused by intake leaks, exhaust leaks, ignition faults, fuel-system problems, or wiring damage. Professional installation and code clearing may be recommended after fitting the replacement sensor.
