Walker Products 350-34072 oxygen sensor for the 1988 Toyota Corolla 4-cylinder 1.6L and other vehicles measures the oxygen content of the exhaust gas. This Walker Products oxygen sensor is made for its specific application and fitment position and sends the ECU diagnostic feedback.
- Electrodes made of a gas-permeable platinum layer
- Coating protects the electrode surfaces from contamination and erosion by combustion residue and particulates
- Measures oxygen levels to help fine-tune the air-fuel mixture and fuel economy
- Monitors exhaust gases to help reduce pollutants
Quick facts
- Part: Walker Products 350-34072 oxygen sensor
- Fits: 1988 Toyota Corolla 4-cylinder 1.6L and other vehicles
- Position: Upstream, downstream
- Condition: New
A worn sensor can show up as rough running, higher fuel use or a lit malfunction indicator light, and a damaged wiring harness or connector can be behind any of those, so inspect both for physical damage before replacing the sensor.

Frequently Asked Questions
Is this the Toyota Corolla oxygen sensor for a 1988 model with the 4-cylinder 1.6L engine?
Yes, Walker Products 350-34072 is listed for the 1988 Toyota Corolla 4-cylinder 1.6L; for other years and engines, look up your car in the "Vehicles it fits" section.
What is the thread size on the Walker Products 350-34072?
Walker Products 350-34072 has an M18 - 1.5 thread.
Is the 350-34072 oxygen sensor narrow-band?
Yes. This narrow-band oxygen sensor determines the oxygen content of the exhaust gas and monitors the air-fuel ratio for combustion efficiency.
Is this oxygen sensor for the upstream or downstream position?
The position is listed as both upstream and downstream, so this oxygen sensor is cataloged for either location.
What is the coating on this oxygen sensor for?
A coating guards the electrode surfaces against contamination and erosion from combustion residue and particulates in the exhaust gases. The electrodes are made of a gas-permeable platinum layer.
