Keep your engine's air-fuel feedback accurate with the Delphi Oxygen Sensor ES20141, a direct-fit replacement for the 1994-2002 Honda Accord, 2000-2001 Honda Insight, 1999-2001 Honda Odyssey, and 1994-1996 Honda Prelude. The catalog lists this sensor for both the front (upstream) and rear (downstream) positions, so match the location your vehicle needs.
- Measures exhaust oxygen: generates a voltage signal from the oxygen content in the exhaust stream so the engine control unit can trim fuel delivery and hold the target air-fuel ratio.
- Upstream and downstream coverage: cataloged for both the front (upstream) and rear (downstream) positions on the listed applications.
- Direct-fit replacement: designed to install on the listed Honda applications.
A worn oxygen sensor can slow or skew the feedback signal the ECU relies on. Signs it may need replacing include an illuminated check engine light, reduced fuel economy, or a rough idle — these symptoms can have other causes, so diagnose the source before replacing. If a failed oxygen sensor is the cause, this Delphi unit replaces it.
Interchange: Manufacturer part number ES20141.
