What It Helps Address

• Check engine light related to oxygen sensor performance
• Poor fuel economy caused by incorrect air-fuel readings
• Rough engine operation tied to faulty exhaust feedback
• Elevated exhaust emissions from a failing sensor
• Stored ECU fault codes for the affected sensor circuit

Installation Notes

Before replacement, inspect the sensor wiring harness and connector for heat damage, corrosion, or broken terminals. Confirm the upstream right mounting location, thread size, and connector style before installation. If the original sensor has failed, check related exhaust and wiring conditions so the new sensor can operate correctly.
