Walker Products 250-54013 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 track combustion efficiency. This upstream wide-band air-fuel ratio sensor gives the ECU the diagnostic feedback it needs.

• Wide-band, 4-wire air-fuel ratio sensor for the upstream position
• Electrodes made of a gas-permeable platinum layer
• Measures oxygen levels so the air-fuel mixture can be fine-tuned, which helps fuel economy
• Coating protects the electrode surfaces from contamination and erosion by combustion residue and particulates
• Monitors exhaust gases to help reduce pollutants
• Made for its specific application and fitment position

Quick facts

• Part: Walker Products 250-54013 oxygen sensor
• Fits: 2001-2005 Honda Civic 4-cylinder 1.7L, the 2003-2005 Civic 4-cylinder 1.3L and other vehicles
• Position: Upstream
• Condition: New

A failed sensor can show up as rough running, higher fuel use, more exhaust emissions or a lit malfunction indicator light. With the engine off and cool, look the sensor, wiring harness and connector over for physical damage. These signs alone do not prove the sensor is at fault, since an exhaust leak ahead of it, for example, can skew its readings.

Fits

This upstream oxygen sensor fits the 2001-2005 Honda Civic 4-cylinder 1.7L, the 2003-2005 Civic 4-cylinder 1.3L and the 2002-2004 Honda CR-V 4-cylinder 2.4L. It is also the oxygen sensor for the 2002-2004 Acura RSX 4-cylinder 2.0L. For a 2004 Honda Civic with either the 4-cylinder 1.7L or the 4-cylinder 1.3L, it is the O2 sensor to order. This listing is one sensor, and these cars take one apiece.
