Walker Products 350-34312 oxygen sensor for the 2001-2003 Toyota RAV4 4-cylinder 2.0L and other vehicles measures the oxygen in the exhaust gas to show combustion efficiency. It is built for its specific application and position and gives the ECU the diagnostic feedback it requires.

• Electrodes made of a gas-permeable platinum layer
• Monitors exhaust gases and helps reduce pollutants
• Measures oxygen levels to fine-tune the air-fuel ratio and support normal fuel economy
• Coating protects the electrode surfaces from combustion residue and particulates in the exhaust gases
• Narrow-band sensor with four wires

Quick facts

• Part: Walker Products 350-34312 oxygen sensor
• Fits: 2001-2003 Toyota RAV4 4-cylinder 2.0L and other vehicles
• Position: upstream, downstream, downstream front, downstream rear
• Condition: New

A failing oxygen sensor can show up as the engine running poorly, higher fuel consumption, more exhaust emissions or a lit malfunction indicator light. These signs alone do not prove the sensor is at fault; damaged wiring or a loose connector can look the same, so the sensor, harness and connector are worth a look for physical damage.

Fits

This direct-fit sensor also fits the 2001-2004 Toyota Highlander 4-cylinder 2.4L, and it is an oxygen sensor for the 1998-2005 Lexus GS300 6-cylinder 3.0L. This listing is one sensor, and the fitment calls for one per application.
