Walker Products 350-32018 oxygen sensor for the 1995-1997 Toyota Corolla 4-cylinder 1.8L, the 1996-1997 Corolla 4-cylinder 1.6L and other vehicles measures the oxygen in the exhaust gas to show how efficiently the engine burns fuel. Each Walker part number is made for its own application and fitting position, and it returns the diagnostic feedback the ECU expects.
- Measures the oxygen content of the exhaust gas to monitor the air-fuel ratio and combustion efficiency
- Oxygen readings help fine-tune the air-fuel mixture for fuel economy
- Electrodes made of a gas-permeable platinum layer
- Coating protects the electrode surfaces from contamination and erosion by combustion residue and particulates
- Monitors exhaust gases and helps reduce pollutants
Quick facts
- Part: Walker Products 350-32018 oxygen sensor
- Fits: the 1995-1997 Toyota Corolla 4-cylinder 1.8L, the 1996-1997 Corolla 4-cylinder 1.6L and other vehicles
- Position: Upstream, downstream
- Condition: New
Rough running, higher fuel use, more exhaust emissions or a lit malfunction indicator light can mean the sensor is worn, though a damaged wiring harness or connector can be behind them as well, so inspect both for physical damage first.
Fits
This is a direct-fit replacement for vehicles that include the 1995-1997 Toyota Corolla 4-cylinder 1.8L, the 1996-1997 Corolla 4-cylinder 1.6L, the 1995-1997 Geo Prizm 4-cylinder 1.8L, the 1996-1997 Prizm 4-cylinder 1.6L and the 1992-1995 Toyota MR2 4-cylinder 2.2L, with a quantity of one for each.

Frequently Asked Questions
Is this the right Toyota Corolla oxygen sensor for the 1995-1997 4-cylinder 1.8L or the 1996-1997 4-cylinder 1.6L?
Yes. Walker Products 350-32018 fits the 1995-1997 Toyota Corolla 4-cylinder 1.8L and the 1996-1997 Corolla 4-cylinder 1.6L, and each takes one.
Is this a Toyota MR2 oxygen sensor for the 1992-1995 4-cylinder 2.2L?
Yes. Walker Products 350-32018 fits the 1992-1995 Toyota MR2 4-cylinder 2.2L, and that engine takes one.
Does Walker Products 350-32018 use narrow-band technology?
Yes. This oxygen sensor is narrow-band, with 2 wires and an M18 - 1.5 thread.
Which position does this oxygen sensor go in, upstream or downstream?
This part number is listed for both the upstream and downstream positions. The listing is one sensor.
What does the coating on this oxygen sensor protect?
The coating guards the electrode surfaces against contamination and erosion from combustion residue and particulates in the exhaust gas. The electrodes themselves are a gas-permeable platinum layer.
