Walker Products Oxygen Sensor P/N:350-341045

Keep your engine computer supplied with exhaust-oxygen feedback using the Walker Products oxygen sensor 350-341045. It is a heated, 4-wire, narrow-band sensor built for direct-fit installation in the downstream position. It is listed for many models from Ford and Lincoln, among them the 2018-2021 Ford F-150, 2018-2022 Ford Mustang and 2018-2021 Ford Expedition. See the Buyer's Guide tab for the full list.

This sensor measures combustion efficiency by reading the amount of oxygen in the exhaust gas. Walker Products designs its oxygen sensors as OE replacements. Each part number is made for its specific application and fitment position, and supplies the diagnostic feedback the ECU requires.

• Oxygen monitoring: Determines the oxygen content of the exhaust gas, helping the ECU monitor and fine-tune the air-fuel ratio.
• Platinum electrodes: The electrodes are made of a gas-permeable platinum layer.
• Protective coating: Helps prevent combustion residue and exhaust particulates from contaminating and eroding the electrode surfaces.
• Connection: Female oblong connector with four female spade terminals, four 20-gauge wires and a threaded mount.

Position: Downstream, including the downstream left and downstream right locations on applicable vehicles. The number of sensors needed varies by application.

A failed sensor may cause poor running, higher fuel consumption, increased emissions, stored fault codes or a lit malfunction indicator light. Diagnose the cause before replacing it, and inspect the wiring harness and connector for damage.

This is a standard replacement grade part from an ISO 9001/TS 16949 certified company. Country of origin: China.
