Bosch Oxygen Sensor P/N:13644
Bosch 13885 oxygen sensor for the 1999-2003 Mazda Protege 4-cylinder 1.6L measures oxygen in the exhaust and reports it to the ECU. This Bosch O2 sensor is a narrow-band heated design for the downstream position.
A check engine light, rough running or lower fuel economy can be signs of a tired oxygen sensor. A vacuum leak, an exhaust leak or a misfire can show up the same way, so find the cause before buying. This listing is one sensor, and the car takes one in the downstream position.
This downstream sensor for the 1999-2003 Mazda Protege 4-cylinder 1.6L (L4-1.6L) is a direct-fit replacement.
