Product Details
Walker Products designs its engine management and oxygen/air-fuel sensors as OE replacement parts for vehicle-specific applications. This sensor is made for the correct fitment position and connector style, helping the ECU receive the expected diagnostic feedback from the exhaust system. The Walker OE Replacement line focuses on application-matched service parts for modern engine management systems, including sensors used to monitor air-fuel control and emissions performance.
Use part number 350-341068 when replacing the upstream right oxygen sensor on a 2020 Chevrolet Silverado 1500 or 2020 GMC Sierra 1500. This part cross-references Bosch (e.g., 17025) for the same application.
Common Issues This Sensor Can Address
- Check engine light related to oxygen sensor performance
- Poor fuel economy caused by incorrect exhaust feedback
- Rough engine operation from inaccurate air-fuel readings
- Increased exhaust emissions from a failing upstream sensor
- Fault codes stored in the ECU for the affected sensor circuit
Installation Notes and Tips
Confirm the upstream right location before installation and compare the connector, terminal style, and harness routing to the original sensor. Inspect the sensor wiring harness and connector for heat damage, abrasion, or corrosion, since physical damage can shorten service life and affect operation. Verify thread size and mounting type match the vehicle before tightening the sensor into the exhaust bung.
