Walker Products 250-54065 oxygen sensor for the 2007-2009 Honda CR-V 4-cylinder 2.4L and other vehicles measures the oxygen in the exhaust gas. This 4-wire wide-band sensor is made for its fitment position and sends the diagnostic feedback the ECU needs.

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

Quick facts

• Part: Walker Products 250-54065 oxygen sensor
• Fits: 2007-2009 Honda CR-V 4-cylinder 2.4L and other vehicles

Rough running, higher fuel use, more exhaust emissions or a lit check engine light can mean the sensor is failing. Before you replace it, look over the wiring harness and connector for physical damage with the engine off and cool, because damage there can also shorten a sensor's life.
