Bosch Oxygen Sensor P/N:13687
Bosch 15409 oxygen sensor for the 2003 Honda Accord 4-cylinder 2.4L sends air-fuel-ratio readings from the exhaust to the ECU. This Bosch O2 sensor is a downstream unit that helps the ECU hold stable combustion control and reduce emissions.
A check engine light, rough running or lower fuel economy can mean a worn oxygen sensor. A vacuum leak, an exhaust leak, a misfiring spark plug or damaged wiring can also be behind those signs, so find the cause before you buy. If a worn downstream sensor is the cause, this one replaces it.
Bosch 15409 is a direct-fit replacement oxygen sensor for the 2003 Honda Accord 4-cylinder 2.4L (L4-2.4L), in the downstream position.
