Product Details
Walker Products Engine Management and Oxygen/Air-Fuel sensors are developed as original equipment replacement parts for a wide range of vehicles. This Walker 350-33055 oxygen sensor is designed for the upstream position on 1993 Volvo 240 California emissions ESV vehicles, where accurate exhaust feedback is critical to engine management. The heated sensor design helps the ECU monitor air-fuel mixture and adjust fuel delivery based on exhaust conditions.
Walker Products Aftermarket focuses on application-specific sensor fitment, and this part number is built for the listed vehicle and position rather than universal use. If your Volvo 240 is showing sensor-related fault codes, poor fuel economy, elevated emissions, or a malfunction indicator light, the oxygen sensor, wiring harness, and connector should all be inspected for damage. This part cross-references no listed interchange numbers in the provided data.
What This Sensor Helps Address
- Check engine light related to upstream oxygen sensor performance
- Rough running caused by incorrect air-fuel feedback
- Increased fuel consumption from inaccurate exhaust readings
- Higher exhaust emissions on California emissions ESV vehicles
- Fault codes stored in the ECU for sensor or related system issues
Installation Notes
Fits 1993 Volvo 240, upstream. Confirm the connector shape, wire count, and threaded mounting style before installation. Inspect the sensor harness and connector for heat damage, corrosion, or abrasion, since physical damage can shorten sensor life and affect signal quality. Verify the application is the California emissions ESV configuration listed for this part number.
Quality Assurance
Walker Products has supplied engine management and fuel system components since 1946 and manufactures to automotive ISO 9001/TS 16949 standards. The 350-33055 is built as an OE-style replacement oxygen sensor for the specified application and position.
