Walker Products 250-22052 oxygen sensor for the 1993-1994 Toyota Corolla 4-cylinder 1.8L, the 1993-1995 Corolla 4-cylinder 1.6L and other vehicles senses the oxygen in the exhaust gas and sends the reading to the engine computer. The ECU uses that feedback to follow combustion efficiency.
- Determines the oxygen content of the exhaust gas to monitor the air-fuel ratio
- Electrodes made of a gas-permeable platinum layer
- Monitors exhaust gases and helps reduce pollutants
- Oxygen readings let the air-fuel mixture be fine-tuned for fuel economy
- Coating protects the electrode surfaces from contamination and erosion by combustion residue and particulates
Quick facts
- Part: Walker Products 250-22052 oxygen sensor
- Fits: 1993-1994 Toyota Corolla 4-cylinder 1.8L, the 1993-1995 Corolla 4-cylinder 1.6L and other vehicles
- Position: Upstream, downstream
- Condition: New
A failing sensor can show up as an engine that runs poorly, higher fuel use, more exhaust emissions or a lit malfunction indicator light, though other faults produce those signs too. Before you replace it, look over the sensor, its wiring harness and the connector for physical damage, with the engine off and cool.
Fits
This Walker Products oxygen sensor is listed for a wide range of Toyota and Geo models, including the 1993-1994 Geo Prizm 4-cylinder 1.8L, the 1993-1995 Prizm 4-cylinder 1.6L and the 1991-1995 Toyota Previa 4-cylinder 2.4L. This listing is one sensor, and the 1993-1994 Toyota Corolla 4-cylinder 1.8L takes one. If your car isn't named here, check it by year and engine in the "Vehicles it fits" section.

Frequently Asked Questions
Will this oxygen sensor fit the 1993-1995 Toyota Corolla 4-cylinder 1.6L?
Yes. Walker Products 250-22052 is listed for the 1993-1995 Toyota Corolla 4-cylinder 1.6L and the 1993-1994 Corolla 4-cylinder 1.8L. For other cars, use the "Vehicles it fits" section.
Does this oxygen sensor fit the 1991-1995 Toyota Previa 4-cylinder 2.4L?
Yes. Walker Products 250-22052 is listed for the 1991-1995 Toyota Previa 4-cylinder 2.4L, and that vehicle takes one sensor.
Is the Walker Products 250-22052 an upstream or downstream oxygen sensor?
This oxygen sensor is listed for both upstream and downstream positions. It is built for its specific application and fitment position on the vehicle.
What can a failed oxygen sensor do to how the engine runs?
A failed sensor might make the engine run poorly, raise fuel consumption or exhaust emissions, or turn on the malfunction indicator light. Newer vehicles may also store a fault code in the ECU.
Is the Walker Products 250-22052 a narrow-band sensor?
Yes. Walker Products 250-22052 is a narrow-band, 2-wire oxygen sensor with a mounting flange and a direct-fit design.
