Walker Products Oxygen Sensor P/N:250-241242
Walker Products 250-24388 oxygen sensor for the 2000-2002 Kia Spectra 4-cylinder 1.8L and other vehicles measures the oxygen in the exhaust gas to show how efficiently the engine burns fuel. It is a direct-fit narrow-band sensor made for the downstream position.
A failing sensor can show up as rough running, higher fuel use, more exhaust emissions or a lit malfunction indicator light, and newer vehicles may store a related fault code. These signs alone do not prove the sensor is the problem, since an exhaust leak near it can give similar readings. With the engine off and cool, you can also look over the sensor, wiring harness and connector for physical damage.
This oxygen sensor fits the 2000-2002 Kia Spectra 4-cylinder 1.8L and the 1998-2001 Kia Sephia 4-cylinder 1.8L in the downstream position. This listing is one sensor, and both cars call for one in that position.
Fit and size
Build and materials
Is this an oxygen sensor for the 2000-2002 Kia Spectra 4-cylinder 1.8L?
Yes. Walker Products 250-24388 is a downstream narrow-band sensor listed for the 2000-2002 Kia Spectra 4-cylinder 1.8L.
Will this oxygen sensor fit the 1998-2001 Kia Sephia 4-cylinder 1.8L?
Yes, this downstream sensor is listed for the 1998-2001 Kia Sephia 4-cylinder 1.8L, and that car takes one.
Is this Walker Products oxygen sensor narrow-band or wideband?
It is narrow-band. Walker Products 250-24388 is a 4-wire, direct-fit sensor for the downstream position.
Could a lit check engine light mean this downstream oxygen sensor needs replacing?
It can, because a failed sensor may light the malfunction indicator light and newer vehicles store a fault code for it. A shop can read the code and test the sensor.
What thread does this oxygen sensor have?
This oxygen sensor is threaded, with an M18 - 1.5 thread. It has 4 wires.
