Walker Products 350-34092 oxygen sensor for the 1997-2001 Toyota Camry 4-cylinder 2.2L or V6 3.0L and other vehicles sends the engine computer a reading of the oxygen left in the exhaust gas. Each part number is made for its specific application and fitment position, and it gives the ECU the diagnostic feedback that application needs.
- Reads oxygen levels in the exhaust to help fine-tune the air-fuel mixture and support fuel economy
- Monitors the air-fuel ratio from the oxygen content of the exhaust gas to track combustion efficiency
- Coating protects the electrode surfaces from contamination and erosion by combustion residue and particulates in the exhaust gas
- Electrodes made of a gas-permeable platinum layer
Quick facts
- Part: Walker Products 350-34092 oxygen sensor
- Fits: 1997-2001 Toyota Camry 4-cylinder 2.2L or V6 3.0L and other vehicles
- Position: upstream, downstream, downstream left, downstream right, downstream front, downstream rear
- Condition: New
A failed sensor might show up as the engine running poorly, higher fuel consumption or a lit malfunction indicator light. Before you replace the sensor, rule out damage to its wiring harness and connector, and have the stored ECU fault codes read, since some relate to the sensor's associated systems.
Fits
It is also a direct-fit oxygen sensor for the 2014-2019 Toyota Corolla 4-cylinder 1.8L and the 1998-2005 Lexus GS300 6-cylinder 3.0L.

Frequently Asked Questions
Is this the right Toyota Camry oxygen sensor for the 1997-2001 model with the 4-cylinder 2.2L or V6 3.0L?
Yes, Walker Products 350-34092 is a direct-fit sensor for the 1997-2001 Toyota Camry 4-cylinder 2.2L or V6 3.0L. It also fits many other vehicles, so look up your own car in the "Vehicles it fits" section.
Is this Walker Products oxygen sensor narrow-band or wideband?
Walker Products 350-34092 is a narrow-band sensor with four wires, made as a direct fit for its specific application and fitment position.
What is the coating on this oxygen sensor for?
The coating protects the electrode surfaces from contamination and erosion by combustion residue and particulates in the exhaust gas. The electrodes themselves are made of a gas-permeable platinum layer.
Can a bad oxygen sensor light up the malfunction indicator?
Yes. A failed sensor might light the malfunction indicator or raise exhaust emissions, and a shop can read the stored fault codes to find the cause.
Does the Walker Products 350-34092 cross-reference to CTK-OSTO4015?
Yes. CTK-OSTO4015 is a cross-reference number that this Walker Products 350-34092 sensor replaces.
