Walker 350-34183 Oxygen Sensor - Downstream Rear, Downstream Right or Upstream Right
Walker OE Replacement Oxygen Sensor
Walker OE Replacement part number 350-34183 is a specific-fit, heated narrow-band oxygen sensor built for direct replacement applications. It is engineered for vehicles that rely on accurate exhaust feedback to help the ECU manage fuel delivery and emissions.
Compatible With Jeep Wrangler and Ram ProMaster 1500, ProMaster 2500, and ProMaster 3500 applications in the listed positions, this sensor is designed around the original mounting and connector style for a straightforward service replacement.
Key Features
- Heated narrow-band oxygen sensor for OE-style engine management feedback
- Specific fit application with threaded mounting
- 4-wire design with female connector and female terminals
- Oblong connector shape for vehicle-specific integration
- M18 x 1.5 thread size and 22 mm wrench size
- Walker OE Replacement line for direct-fit sensor service
Product Details
Walker Products develops engine management and oxygen/air-fuel sensors as OE replacement parts for a wide range of vehicles. Part number 350-34183 is built for the specified application and position so the ECU receives the expected diagnostic signal from the exhaust stream. This matters on Jeep Wrangler upstream right applications and Ram ProMaster 1500, ProMaster 2500, and ProMaster 3500 downstream right or downstream rear applications where sensor accuracy affects fuel control and emissions monitoring.
This part cross-references no listed interchange numbers in the provided data.
What It Helps Address
- Check engine light related to oxygen sensor performance
- Poor fuel economy caused by incorrect exhaust feedback
- Rough engine operation from inaccurate air-fuel data
- Elevated exhaust emissions from a failing sensor
- Fault codes stored in the ECU for the affected sensor circuit
Installation Notes
Verify the sensor position before installation: Fits 2018-2026 Jeep Wrangler, upstream right; Fits 2022-2025 Ram ProMaster 1500, downstream right or downstream rear; Fits 2022-2025 Ram ProMaster 2500, downstream right or downstream rear; Fits 2022-2025 Ram ProMaster 3500, downstream right or downstream rear. Inspect the sensor, wiring harness, and connector for damage before replacement, since physical wear can shorten service life and affect signal quality.
Use the correct 22 mm wrench size and confirm the M18 x 1.5 threaded mounting point matches the vehicle application. For best results, compare the connector shape, wire count, and position against the original sensor before installation.
Quality Assurance
Walker Products has been manufacturing engine management components since 1946 and operates as an ISO 9001/TS 16949 certified company. The OE Replacement line is built to match the specified vehicle application, fitment position, and ECU feedback requirements for dependable service replacement.
