Walker Products 250-23003 oxygen sensor for the 1987 Dodge Charger 4-cylinder 2.2L and other vehicles measures the oxygen content of the exhaust gas. This Walker Products oxygen sensor is made for its specific application and fitment position, and it gives the ECU the diagnostic feedback it expects.
- Electrodes with a gas-permeable platinum layer
- Measures oxygen levels to help fine-tune the air-fuel mixture and support fuel economy
- Coating protects the electrode surfaces from contamination and erosion by combustion residue and particulates in the exhaust gases
- Monitors exhaust gases to help reduce pollutants
- Narrow-band sensor with a direct-fit design
Quick facts
- Part: Walker Products 250-23003 oxygen sensor
- Fits: 1987 Dodge Charger 4-cylinder 2.2L and other vehicles
- Position: Upstream
- Condition: New
A failing sensor can show up as rough running, higher fuel consumption, more exhaust emissions or a lit malfunction indicator light, though the sensor's wiring harness and connector can be behind those signs too. Look both over for physical damage before you replace the sensor.
Fits
This upstream sensor is also an oxygen sensor for the 1987 Dodge Dakota V6 3.9L and the 1987-1988 Dakota 4-cylinder 2.2L, and for the 1987-1988 Dodge Grand Caravan 4-cylinder 2.5L or V6 3.0L. If your car is not one of those, open the "Vehicles it fits" section and check your exact model and engine there.

Frequently Asked Questions
Is the Walker Products 250-23003 the right 1987 Dodge Charger oxygen sensor with the 4-cylinder 2.2L?
Yes. The Walker Products 250-23003 is listed as an upstream sensor for the 1987 Dodge Charger 4-cylinder 2.2L. For other models, use the "Vehicles it fits" section to check your engine.
What thread size does this oxygen sensor have?
The 250-23003 has an M18 - 1.5 thread.
Is the Walker Products 250-23003 a narrow-band or wideband sensor?
It is a narrow-band sensor. It measures the oxygen content of the exhaust gas so combustion efficiency and the air-fuel ratio can be monitored.
What is the platinum layer on this oxygen sensor for?
The electrodes are made with a gas-permeable platinum layer. The coating guards the electrode surfaces against contamination and erosion from combustion residue and exhaust particulates.
Can a worn Walker Products oxygen sensor affect fuel economy?
It can. This sensor measures oxygen levels so the air-fuel mixture can be fine-tuned, and a failing one can raise fuel consumption and exhaust emissions.
