Walker Products 350-34282 oxygen sensor for the 2009-2013 Toyota Corolla 4-cylinder 1.8L, the 2011-2012 Corolla 4-cylinder 2.4L and other vehicles measures the amount of oxygen in the exhaust gas to show combustion efficiency. This narrow-band sensor is made for its specific application and fitment position, and it sends the diagnostic feedback the ECU needs.
- Monitors the air-fuel ratio from the oxygen content of the exhaust gas
- Electrodes with a gas-permeable platinum layer
- Oxygen readings help fine-tune the air-fuel mixture and support fuel economy
- Exhaust gas monitoring helps reduce pollutants
- Coating protects the electrode surfaces from contamination and erosion by combustion residue and particulates
Quick facts

A failing oxygen sensor can show up as rough running, higher fuel consumption, more exhaust emissions or a lit malfunction indicator light. None of those signs alone proves the sensor is the problem, since a damaged wiring harness or connector can produce them as well. Newer vehicles store fault codes in the ECU, and some relate to the sensor.
Fits
This oxygen sensor is listed for a wide range of Toyota, Pontiac and Lexus models. That includes an oxygen sensor for the 2009-2013 Toyota Matrix 4-cylinder 2.4L, the 2009-2014 Matrix 4-cylinder 1.8L and the 2009-2010 Pontiac Vibe 4-cylinder 1.8L or 2.4L. If your car isn't named here, look it up by year and engine in the "Vehicles it fits" section.

Frequently Asked Questions
Is this the right oxygen sensor for a 2009-2013 Toyota Corolla 4-cylinder 1.8L?
Yes. Walker Products 350-34282 is listed for the 2009-2013 Toyota Corolla 4-cylinder 1.8L and the 2011-2012 Corolla 4-cylinder 2.4L. Other cars are in the "Vehicles it fits" section.
Does this Walker Products oxygen sensor have a protective coating?
Yes. A coating protects the electrode surfaces from contamination and erosion by combustion residue and particulates in the exhaust gas, and the electrodes have a gas-permeable platinum layer.
Is Walker Products 350-34282 a narrow-band oxygen sensor?
Yes. Walker Products 350-34282 is a narrow-band, 4-W direct-fit oxygen sensor with an M18 - 1.5 thread and a downstream position.
Will a worn oxygen sensor turn on the check engine light?
Yes. A failed oxygen sensor can trigger the malfunction indicator light, and it may also cause rough running, higher fuel consumption or more exhaust emissions. A shop can read the stored fault codes.
Is CTK-OSTO4009 the same as this oxygen sensor?
Yes. CTK-OSTO4009 is a cross-reference number for this oxygen sensor, which Walker Products sells as 350-34282.
