Product Details

The Walker Products OE brand focuses on engine management and oxygen/air-fuel sensors built for exact application fitment and ECU feedback requirements. Part number 250-22001 is a non-heated oxygen sensor designed for upstream positions across a wide range of 1979-1995 vehicles, including Cadillac DeVille, Cadillac Eldorado, Chevrolet El Camino, and Jeep CJ5. This part number is used where the vehicle calls for a threaded, 2-wire upstream oxygen sensor with the listed connector and harness configuration.

This part cross-references no listed aftermarket part numbers in the provided data.

Common Issues This Sensor Can Address

• Illuminated malfunction indicator light related to oxygen sensor performance
• Poor engine operation caused by inaccurate exhaust feedback
• Increased fuel consumption from incorrect air-fuel correction
• Higher exhaust emissions from a degraded upstream sensor
• Fault codes stored in the ECU for the affected sensor circuit

Installation Notes and Tips

Verify the vehicle’s emissions configuration, bank, and sensor position before ordering. This oxygen sensor is listed for upstream right, upstream left, upstream front, upstream rear, and general upstream applications depending on the vehicle. Inspect the sensor wiring harness and connector for damage before installation, since physical wear can shorten sensor life and affect signal quality. Confirm thread size, connector shape, and harness length against the original part.
