Common Issues This Part Addresses

• Check engine light related to downstream oxygen sensor faults
• Incorrect exhaust oxygen readings from a worn sensor
• Reduced fuel economy caused by inaccurate sensor feedback
• Rough or inconsistent engine performance tied to sensor degradation
• Replacement needs after contamination or age-related sensor wear

Installation Notes and Tips

Verify the connector, wire count, and downstream location before installation. This is a specific-fit sensor, so compare the original part number and vehicle application before ordering. Inspect the exhaust threads and harness routing during replacement to ensure the sensor seats correctly and the wiring is kept clear of heat sources.

Quality Assurance

Denso manufactures and tests this oxygen sensor to OE standards for direct replacement use. The aluminum oxide trap layer is part of the sensor design to help protect the sensing element from contamination and support consistent operation over time.
