What It Helps Address

• Check engine light related to oxygen sensor performance
• Incorrect air-fuel feedback from a worn upstream sensor
• Rough idle or drivability issues tied to exhaust sensor faults
• Failed emissions inspection caused by sensor-related trouble codes
• Slow or inaccurate sensor response on the listed Nissan and INFINITI models
