DENSO Auto Parts Oxygen Sensor P/N:234-4044
DENSO Auto Parts 234-4604 oxygen sensor for the 2000-2002 Toyota Celica 4-cylinder 1.8L reads the oxygen in the exhaust and reports it to the engine computer. This DENSO Auto Parts oxygen sensor is a heated, narrow-band unit for the upstream position, with a threaded mount.
A worn oxygen sensor can show up as a check engine light, poor fuel economy or a rough idle. These signs alone do not prove the sensor is the problem, since an exhaust leak near the sensor can give similar readings.
This oxygen sensor is a direct-fit part for the 2000-2002 Toyota Celica 4-cylinder 1.8L.
