Walker Products 350-64073 oxygen sensor for the 2011-2012 Toyota Corolla 4-cylinder 2.4L, the 2011-2024 Corolla 4-cylinder 1.8L and other vehicles measures the oxygen in the exhaust gas so the ECU can judge combustion efficiency. This Walker Products oxygen sensor is a four-wire, wide-band air-fuel ratio type.
- Coating protects the electrode surfaces from contamination and erosion by combustion residue and particulates
- Electrodes made of a gas-permeable platinum layer
- Reads oxygen levels in the exhaust so the air-fuel mixture can be fine-tuned, which supports fuel economy
- Monitors exhaust gases to help reduce pollutants
- Made for its specific application and fitment position to return the diagnostic feedback the ECU expects
Quick facts
- Part: Walker Products 350-64073 oxygen sensor
- Fits: 2011-2012 Toyota Corolla 4-cylinder 2.4L, the 2011-2024 Corolla 4-cylinder 1.8L and other vehicles
- Position: Upstream, upstream left, upstream right, upstream rear, upstream front
- Condition: New
A damaged wiring harness or connector can be behind a rough-running engine, higher fuel consumption or a lit malfunction indicator light just as a failed sensor can, so find the cause before buying. Newer vehicles store fault codes in the ECU, and some of them point to the sensor.
Fits
As an upstream oxygen sensor, it fits the 2020-2022 Toyota Highlander V6 3.5L and the 2013-2015 Lexus IS250 V6 2.5L, along with many other Toyota, Lexus and Scion models. This listing is one sensor, and the 2020-2022 Toyota Highlander V6 3.5L takes one.

Frequently Asked Questions
Is this a Toyota Corolla oxygen sensor for the 2011-2012 Corolla 4-cylinder 2.4L or the 2011-2024 Corolla 4-cylinder 1.8L?
Yes. Walker Products 350-64073 fits both of those Corolla engines. To check a different car, look it up in the "Vehicles it fits" section.
Is this a Toyota Highlander oxygen sensor for the 2020-2022 Highlander V6 3.5L?
Yes. Walker Products 350-64073 fits the 2020-2022 Toyota Highlander V6 3.5L, which takes one sensor.
Is this upstream oxygen sensor a narrow-band or a wide-band type?
It is a wide-band type. This four-wire air-fuel ratio sensor determines the oxygen content of the exhaust gas to monitor combustion efficiency.
What does the platinum coating on this oxygen sensor do?
The electrodes are made of a gas-permeable platinum layer, and the coating prevents contamination and erosion of the electrode surfaces by combustion residue and particulates in the exhaust.
What signs can a failing oxygen sensor show?
A failed sensor might make the engine run poorly, raise fuel consumption or light the malfunction indicator light. A shop can read the stored fault codes.
