What It Helps Address

• Check engine light related to oxygen sensor performance
• Rough running caused by incorrect exhaust feedback
• Increased fuel consumption from inaccurate air-fuel correction
• Higher exhaust emissions from a failing sensor
• Fault codes stored in the ECU for sensor-related issues

Installation Notes and Tips

• Match the vehicle year, make, model, and sensor position exactly before ordering.
• Inspect the sensor wiring harness and connector for damage before installation.
