Walker Products 350-64025 front oxygen sensor for the 2001-2003 Toyota RAV4 4-cylinder 2.0L measures combustion efficiency from the amount of oxygen in the exhaust gas. Its wide-band, 4-wire air fuel ratio design gives the ECU the diagnostic feedback it needs.

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

Quick facts

• Part: Walker Products 350-64025 oxygen sensor
• Fits: 2001-2003 Toyota RAV4 4-cylinder 2.0L
• Position: Upstream front
• Condition: New

A failing oxygen sensor can show up as a poorly running engine, higher fuel consumption or a lit malfunction indicator light. The sensor, wiring harness and connector can also be inspected for physical damage with the engine off and cool. These signs alone do not prove the sensor is at fault, since an exhaust leak can cause similar symptoms.
