Vehicle Fitment

• Fits 2000-2001 Honda Insight, upstream.
• Fits 1996-2000 Honda Civic, upstream.
• Fits 1992 Honda Civic, upstream.
• Fits 1993-1995 Honda Civic, upstream; non-California emissions certified applications only.

Common Issues This Sensor May Address

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

Installation Notes and Tips

Confirm the vehicle is listed by year, model, and emissions configuration before ordering. This sensor is for upstream Bank 1 Sensor 1 positions on the specified Honda Civic and Honda Insight applications, and the 1993-1995 Honda Civic listing excludes California emissions-certified vehicles. Inspect the sensor connector, wiring harness, and surrounding exhaust components for damage before installation, since physical wear can shorten sensor life and affect signal quality.
