Walker Products 350-32001 oxygen sensor for the 1993-1994 Toyota Corolla 4-cylinder 1.8L, the 1993-1995 Corolla 4-cylinder 1.6L and other vehicles measures combustion efficiency from the amount of oxygen in the exhaust gas. This Walker Products oxygen sensor is a narrow-band unit with a mounting flange, made for its specific application and position, and it gives the ECU the diagnostic feedback it expects.
- Determines the oxygen content of the exhaust gas to monitor the air-fuel ratio
- Monitors exhaust gases and reduces pollutants for a cleaner environment
- Measures oxygen levels so the air-fuel mixture can be fine-tuned, which helps fuel economy
- Electrodes with a gas-permeable platinum layer
- Coating protects the electrode surfaces from contamination and erosion by combustion residue and particulates
Quick facts
- Part: Walker Products 350-32001 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
Poor running, higher fuel consumption, more exhaust emissions or a lit malfunction indicator light can mean the sensor is failing, though its wiring harness or connector can be at fault instead, so look both over for physical damage first.
Fits
This 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. Every car listed takes a single sensor, and this listing is one sensor. If your car is not named here, look it up by year and engine in the "Vehicles it fits" section.

Frequently Asked Questions
Will this Toyota Corolla oxygen sensor work on a 1993-1994 Corolla 4-cylinder 1.8L?
Yes. The Walker Products 350-32001 is listed for the 1993-1994 Toyota Corolla 4-cylinder 1.8L and the 1993-1995 Corolla 4-cylinder 1.6L, with one sensor per car.
Is there a Previa oxygen sensor here for the 1991-1995 Toyota Previa 4-cylinder 2.4L?
Yes. The Walker Products 350-32001 is listed for the 1991-1995 Toyota Previa 4-cylinder 2.4L, and that vehicle takes one sensor.
Is the Walker Products 350-32001 narrow-band, and what thread does it have?
It is a narrow-band oxygen sensor with an M18 - 1.5 thread and a flange mount. It is listed for upstream and downstream positions.
What symptoms can a failed oxygen sensor like this show?
The engine can run poorly, fuel consumption and exhaust emissions can rise, or the malfunction indicator light can come on. Newer vehicles also store fault codes in the ECU, and some relate to the sensor.
What does the coating on this oxygen sensor's electrodes do?
The electrodes have a gas-permeable platinum layer, and the coating keeps combustion residue and particulates in the exhaust from contaminating or eroding the electrode surfaces.
