What It Helps Address

• Check engine light or MIL illumination related to oxygen sensor faults
• Poor engine performance caused by inaccurate exhaust feedback
• Increased fuel consumption from incorrect air-fuel correction
• Higher exhaust emissions from a degraded downstream sensor
• Stored ECU fault codes tied to the affected sensor circuit

Installation Notes and Tips

Before replacement, inspect the sensor wiring harness and connector for heat damage, corrosion, or physical wear. Confirm the vehicle position carefully: this listing covers 2005-2006 Cadillac XLR downstream left and downstream right applications only. Use the threaded mounting location and connector style shown in the specifications to verify match before installation.
