Walker Products 250-24446 center oxygen sensor for the 2001-2005 Honda Civic 4-cylinder 1.7L, the 2003-2005 Civic 4-cylinder 1.3L and other vehicles measures the oxygen in the exhaust gas to show how efficiently the engine burns fuel. It is made for its application and fitment position and gives the ECU the diagnostic feedback it requires.
- Narrow-band sensor with 4 wires
- Monitors exhaust gases to help reduce pollutants
- Coating guards the electrode surfaces against contamination and erosion from combustion residue and particulates
- Electrodes made of a gas-permeable platinum layer
- Measures oxygen levels to help fine-tune the air-fuel mixture for fuel economy
Quick facts
- Part: Walker Products 250-24446 oxygen sensor
- Fits: 2001-2005 Honda Civic 4-cylinder 1.7L, the 2003-2005 Civic 4-cylinder 1.3L and other vehicles
- Position: Center, downstream
- Condition: New
A failing sensor can show up as rough running, higher fuel consumption, more exhaust emissions or a lit malfunction indicator light. A damaged wiring harness or connector, or a different fault stored in the ECU, can be behind these signs too, so find the cause before buying. With the engine off and cool, look the sensor, harness and connector over for physical damage.
Fits
This oxygen sensor is a direct fit for the 2001-2005 Honda Civic 4-cylinder 1.7L and the 2003-2005 Civic 4-cylinder 1.3L. It also fits as an oxygen sensor for the 2005-2006 Acura RSX 4-cylinder 2.0L. This listing is one sensor, and the 2005-2006 Acura RSX 4-cylinder 2.0L takes one, the same as the Civic.

Frequently Asked Questions
Is this a 2001-2005 Honda Civic O2 sensor for the 4-cylinder 1.7L?
Yes. Walker Products 250-24446 fits the 2001-2005 Honda Civic 4-cylinder 1.7L, and the 2003-2005 Civic 4-cylinder 1.3L also takes it.
Where does this O2 sensor for a 2004 Honda Civic with the 4-cylinder 1.7L or 1.3L go?
It is a center, downstream sensor. For a 2004 Honda Civic with the 4-cylinder 1.7L or 1.3L, Walker Products 250-24446 is the one listed.
Is the Walker Products 250-24446 a narrow-band sensor?
Yes. This oxygen sensor is narrow-band with 4 wires and an M18 - 1.5 thread. Its electrodes are made of a gas-permeable platinum layer.
How does a failing narrow-band oxygen sensor show up on a newer vehicle?
Newer vehicles store fault codes in the ECU, and some relate to the affected sensor and its systems. The engine can also run poorly, or the malfunction indicator light can come on.
How does the coating on this Walker Products oxygen sensor help?
The coating prevents contamination and erosion of the electrode surfaces by combustion residue and particulates in the exhaust gas.
