Keep the air-fuel data your engine control module depends on with the Delphi Oxygen Sensor ES10937, a specific-fit, front-position replacement for the 2001-2005 Honda Civic [L4-1.7L], 2002-2005 Honda Civic [L4-2.0L], 2003-2005 Honda Civic [L4-1.3L], 2002-2004 Honda CR-V [L4-2.4L], and 2002-2004 Acura RSX [L4-2.0L]. This heated, wide-band sensor threads into the exhaust and measures oxygen content in the exhaust stream, feeding the readings the ECU uses to adjust the air-fuel ratio.
- Heated wide-band sensor: Delphi planar technology covers older conical designs, and the smart design consolidates SKUs without relying on long wires.
- Patented protective coating: helps prevent contamination of the sensing element.
- Validated for all fuel types: including ethanol blends like E85.
- Built to Delphi OE standards: OE tested to 150,000 miles plus 2,000 hours of severe thermal testing.
It arrives as a threaded unit with an M18 - 1.5 metric thread, a 22 mm hex, four male blade terminals, and a square male connector, measuring roughly 380 mm overall with a 350 mm wiring harness. If a failed front oxygen sensor is the cause of a stored O2 sensor trouble code, poor fuel economy, or rough running, this replaces it; diagnose the cause before ordering. Country of origin: China.
Manufacturer part number: ES10937.
