Oxygen Sensor for 1993-1994 Lexus LS400 - Walker 350-32015

Walker Products 350-32015 oxygen sensor for the 1993-1994 Lexus LS400 V8 4.0L reads the oxygen content of the exhaust gas. This downstream sensor gives the engine computer feedback on combustion efficiency.

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

Quick facts

• Part: Walker Products 350-32015 oxygen sensor
• Fits: 1993-1994 Lexus LS400 V8 4.0L
• Position: Downstream
• Condition: New

A failing oxygen sensor can show up as rough running, higher fuel use, more exhaust emissions or a lit check engine light. Those signs alone do not prove the sensor is at fault, since a damaged wiring harness or connector can produce them too, so look those over for physical damage first.

Fits

This downstream oxygen sensor is a direct-fit replacement for the 1993-1994 Lexus LS400 V8 4.0L.
