Oxygen Sensor for 2003-2005 Honda Civic & More - Walker 250-241123

Walker Products 250-241123 oxygen sensor for the 2003-2005 Honda Civic 4-cylinder 1.3L and other vehicles measures the oxygen in the exhaust gas to show how efficiently the engine is burning fuel. It is made for its specific application and position, and it gives the ECU the diagnostic feedback that position calls for.

• Monitors exhaust gases to support lower emissions
• Determines the oxygen content of the exhaust gas and monitors the air-fuel ratio for combustion efficiency
• Coating protects the electrode surfaces from contamination and erosion by combustion residue and particulates
• Electrodes made of a gas-permeable platinum layer
• Measures oxygen levels so the air-fuel mixture can be fine-tuned, which helps fuel economy
• Narrow-band, 4-wire design

Quick facts

• Part: Walker Products 250-241123 oxygen sensor
• Fits: 2003-2005 Honda Civic 4-cylinder 1.3L and other vehicles
• Position: Downstream
• Condition: New

A failing sensor can show up as rough running, higher fuel use, more exhaust emissions or a lit malfunction indicator light. Those signs alone do not prove the sensor is the problem, since a vacuum leak can also produce them. The sensor, wiring and connector should also be checked for physical damage.

Fits

It is an oxygen sensor for the 2003-2005 Honda Civic 4-cylinder 1.3L and for the 2005-2006 Honda CR-V 4-cylinder 2.4L, and it is a direct-fit replacement for both. This listing is one sensor, and both cars take one in the downstream position.
