Walker 350-33016 Oxygen Sensor - Upstream

Walker 350-33016 Oxygen Sensor for Saab 9000

Walker Products 350-33016 is a heated oxygen sensor built as a specific-fit OE replacement for select Saab 9000 applications. It is engineered for upstream placement and provides the ECU with the feedback needed to monitor air-fuel control on the 1992-1993 Saab 9000.

Key Features

• Heated oxygen sensor for faster operating response
• Specific-fit design for the correct application and mounting position
• Upstream placement for Bank 1 Sensor 1 service needs
• 3-wire configuration with 20-gauge wiring
• 47.36 in. wiring harness length and 50.91 in. overall length
• 18.0 mm thread diameter with threaded mounting
• Radiused polygon male connector

Product Details

Walker Products Aftermarket 350-33016 is part of the Walker Products Engine Management and Oxygen/Air-Fuel sensor line, developed as an OE-style replacement for vehicles worldwide. For Saab 9000 owners, this upstream oxygen sensor is listed for 1992-1993 models and is intended for Bank 1 Sensor 1 service where the front oxygen sensor is required. The part number 350-33016 is built to match the specified fitment position so the ECU receives the correct diagnostic feedback.

Walker Products has supplied engine management and fuel system components since 1946, with ISO 9001/TS 16949 certified manufacturing processes supporting consistent application-specific production. This part number 350-33016 is also referenced for the same application as a Walker Products Aftermarket replacement in select Saab 9000 upstream oxygen sensor listings.

What It Helps Address

• Check engine light related to upstream oxygen sensor faults
• Poor fuel economy caused by inaccurate air-fuel feedback
• Rough engine operation from a failing sensor signal
• Higher exhaust emissions from incorrect mixture control
• Stored ECU fault codes tied to the affected sensor circuit

Installation Notes

Confirm the connector shape, thread diameter, wire count, and upstream position before installation. Inspect the sensor wiring harness and connector for heat damage, abrasion, or corrosion, since physical damage can shorten service life. For Saab 9000 applications, verify that the vehicle requires an upstream oxygen sensor for Bank 1 Sensor 1 service before ordering Walker 350-33016.

Quality Assurance

Walker Products manufactures this oxygen sensor as a specific application replacement within its engine management sensor program. The brand’s ISO 9001/TS 16949 certified production standards support consistent fitment and diagnostic feedback for the intended vehicle application.
