Walker 350-341033 Oxygen Sensor - Downstream Left or Downstream Right

Walker Oxygen Sensor for GM Downstream Applications

Walker Products 350-341033 is an OE replacement oxygen sensor engineered for specific downstream positions on select Cadillac and Chevrolet vehicles. It is built to provide the ECU with the diagnostic feedback needed for proper fuel control and emissions monitoring.

Key Features

• OE-style replacement oxygen sensor from Walker Products Aftermarket
• Application-specific fitment for downstream right, downstream left, and downstream positions
• Supports ECU feedback for emissions and engine management systems
• Direct replacement for select Cadillac CT4, CT5, CT6, ATS, CTS, and Chevrolet Camaro models
• Walker Products part number 350-341033

Product Details

Walker Products Aftermarket focuses on engine management and oxygen/air-fuel sensors built for exact vehicle applications. Part number 350-341033 is matched to the required sensor location and is intended to restore the signal the ECU uses to monitor exhaust performance. On affected vehicles, a failing downstream oxygen sensor can contribute to poor engine operation, higher fuel use, increased emissions, and a malfunction indicator light. For diagnosis, inspect the sensor, wiring harness, and connector for damage before replacement. This part cross-references common OE-style replacement needs for the same application.

• Rough running or inconsistent fuel control
• Increased fuel consumption
• Higher exhaust emissions

Installation Notes

Confirm the exact sensor position before ordering, since this part is listed for downstream right, downstream left, and downstream locations depending on vehicle application. Inspect the connector and harness for corrosion, abrasion, or heat damage before installation. Verify the fault code and sensor location against the vehicle service information for Cadillac CT4, CT5, CT6, ATS, CTS, and Chevrolet Camaro applications.
