Walker Products 350-34501 oxygen sensor for the 2002-2003 Toyota Camry 4-cylinder 2.4L and other vehicles measures the oxygen content of the exhaust gas. The Walker Products oxygen sensor is a 4-wire, narrow-band direct-fit unit.
- Built for its specific application and fitment position, with the diagnostic feedback the ECU requires
- Monitors exhaust gases to help reduce pollutants
- Tracks the air-fuel ratio through exhaust oxygen content to support combustion efficiency and fuel economy
- Coating protects the electrode surfaces from contamination and erosion by combustion residue and particulates in the exhaust gases
- Electrodes with a gas-permeable platinum layer
Quick facts
- Part: Walker Products 350-34501 oxygen sensor
- Fits: 2002-2003 Toyota Camry 4-cylinder 2.4L and other vehicles
- Position: Downstream, downstream left, downstream front, downstream rear
- Condition: New
A failing sensor can show up as a rough-running engine, higher fuel consumption, higher exhaust emissions or a lit malfunction indicator light. These signs alone do not prove the sensor is the problem, since an exhaust leak can also throw off the readings.
Fits
Listed for a wide range of Toyota, Lexus and Scion models, it is an oxygen sensor for the 2004-2006 Toyota Sienna V6 3.3L, the 2007-2015 Sienna V6 3.5L, the 2013 Sienna 4-cylinder 2.7L, the 2004-2010 Toyota Highlander V6 3.3L and the 2008-2013 Highlander V6 3.5L.

Frequently Asked Questions
Is 350-34501 the right Toyota Camry oxygen sensor for a 2002-2003 Camry 4-cylinder 2.4L?
Yes, Walker Products 350-34501 is listed for the 2002-2003 Toyota Camry 4-cylinder 2.4L. If your car is another model, look it up in the "Vehicles it fits" section by make, model, year and engine.
Is the Camry O2 sensor 350-34501 for the 2002-2003 Toyota Camry 4-cylinder 2.4L an upstream or downstream sensor?
Walker Products 350-34501 is catalogued as a downstream sensor, and the catalog lists downstream left, front and rear positions across its applications.
What thread and wiring does this narrow-band oxygen sensor have?
This sensor has an M18 - 1.5 thread and four wires, and it is a narrow-band design.
How can I tell if a narrow-band oxygen sensor like this one is failing?
The engine may run poorly, fuel consumption and exhaust emissions may rise, or the malfunction indicator light may come on. With the engine off and cool, look at the sensor, wiring harness and connector for physical damage.
Does CTK-OSTO4001 cross-reference to this Walker Products sensor?
Yes, CTK-OSTO4001 is listed as an interchange number for Walker Products 350-34501.
