Common Issues This Sensor Can Address

• Check engine light related to oxygen sensor performance
• Poor engine operation caused by incorrect exhaust feedback
• Increased fuel consumption from inaccurate air-fuel readings
• Higher exhaust emissions from a failing upstream sensor
• Stored ECU fault codes tied to the affected sensor circuit

Installation Notes

Install this sensor in the upstream position specified for the vehicle application. Before replacement, inspect the sensor wiring harness and connector for physical damage, since damaged wiring can shorten sensor life and affect operation. Confirm thread size, connector shape, and harness routing match the original part before installation.
