Walker Products 250-24340 oxygen sensor for the 2000-2003 Chevrolet Impala V6 3.8L, the 2000-2004 Impala V6 3.4L and other vehicles measures the oxygen in the exhaust gas to show how efficiently the engine burns fuel. This Walker Products oxygen sensor is made for its specific application and position and gives the ECU the diagnostic feedback it expects.
- Four-wire, narrow-band design
- Electrodes made of a gas-permeable platinum layer
- Measures oxygen levels to help fine-tune the air-fuel mixture and support fuel economy
- Monitors exhaust gases to help reduce pollutants
- Coating protects the electrode surfaces from contamination and erosion by combustion residue and particulates in the exhaust gases
Quick facts
- Part: Walker Products 250-24340 oxygen sensor
- Fits: the 2000-2003 Chevrolet Impala V6 3.8L, the 2000-2004 Impala V6 3.4L and other vehicles
- Position: Center, upstream, downstream, upstream right, downstream right, downstream front
- Condition: New
Rough running, higher fuel consumption, more exhaust emissions or a lit malfunction indicator light can mean a failed sensor, though a fault elsewhere in the engine management system may be behind them. Before replacing it, and only with the engine off and cool, look over the sensor, its wiring harness and its connector for physical damage.
Fits
The 2000-2003 Chevrolet Impala V6 3.8L, the 2000-2004 Impala V6 3.4L and the 1996-2002 Chevrolet Camaro V6 3.8L or V8 5.7L take this direct-fit sensor, and so do many other vehicles. Not sure about your car? Look up its year and engine in the "Vehicles it fits" section. This listing is one sensor, and each application takes one for its position.

Frequently Asked Questions
Is this the Chevy oxygen sensor for a 2010-2012 4-cylinder 1.6L?
Yes. Walker Products 250-24340 is listed for the 2010-2012 Chevrolet Chevy with the 4-cylinder 1.6L engine, and that application takes one sensor.
Is this the Camaro oxygen sensor for a 1996-2002 V6 3.8L or V8 5.7L?
Yes. Both the V6 3.8L and the V8 5.7L versions of the 1996-2002 Chevrolet Camaro are listed for Walker Products 250-24340, each taking one sensor.
What thread size does the Walker Products 250-24340 have?
This oxygen sensor has an M18 - 1.5 thread and four wires, which is useful to compare against the sensor you are removing.
How can I tell whether a narrow-band oxygen sensor has failed?
Newer vehicles store fault codes in the ECU, and some relate to the affected sensor. A shop can read those codes and test the sensor, since poor running or a warning light can have other sources.
Is this oxygen sensor universal or direct fit?
It is a direct-fit, narrow-band sensor made for its specific application and position, so it is not a universal-style sensor.
