Oxygen Sensor for 2004-2005 Honda Civic - Walker 350-64023

Walker Products 350-64023 oxygen sensor for the 2004-2005 Honda Civic 4-cylinder 1.7L measures the oxygen in the exhaust gas to show how efficiently the engine burns fuel. This sensor goes in the upstream position and is a 4-wire wide-band air-fuel ratio design.

• Electrodes made of a gas-permeable platinum layer
• Measures oxygen levels to help fine-tune the air-fuel mixture and support fuel economy
• Determines the oxygen content of the exhaust gas and monitors the air-fuel ratio for combustion efficiency
• Monitors exhaust gases to help reduce pollutants
• Coating that protects the electrode surfaces from contamination and erosion by combustion residue and particulates

Quick facts

• Part: Walker Products 350-64023 oxygen sensor
• Fits: 2004-2005 Honda Civic 4-cylinder 1.7L
• Position: Upstream
• Condition: New

A failing sensor can make the engine run poorly, raise fuel consumption or exhaust emissions, or turn on the malfunction indicator light. Before you replace the sensor, look over its wiring harness and connector for physical damage, since damage there can also shorten a sensor's life, and a shop can read the fault codes stored in the ECU.

Fits

The 2004-2005 Honda Civic 4-cylinder 1.7L takes one upstream sensor, and this listing is one sensor. Walker Products builds each part number for its specific application and fitment position, so the ECU gets the diagnostic feedback it expects.
