Oxygen Sensor for 1998-2002 Toyota Corolla & More - Walker 250-241099

Walker Products 250-241099 oxygen sensor for the 1998-2002 Toyota Corolla 4-cylinder 1.8L and other vehicles measures the oxygen content of the exhaust gas. The engine computer uses that reading to monitor the air-fuel ratio and combustion efficiency.

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

Quick facts

• Part: Walker Products 250-241099 oxygen sensor
• Fits: 1998-2002 Toyota Corolla 4-cylinder 1.8L and other vehicles
• Position: Upstream

A failing sensor can show up as rough running, higher fuel use or a lit malfunction indicator light. Those signs alone do not prove the sensor is at fault, because an exhaust leak ahead of it can skew readings too. The sensor, wiring harness and connector should also be checked for physical damage.

Fits

This sensor also fits the 1998-2002 Chevrolet Prizm 4-cylinder 1.8L. A 2000 or 2002 Toyota Corolla O2 sensor for the 4-cylinder 1.8L engine is covered by this same part number. This listing is one upstream sensor, and the engine takes one.
