Walker Products 350-34691 oxygen sensor for the 2000-2008 Ford F-150 V8 5.4L, the 2004-2008 F-150 V8 4.6L, the 2005-2008 F-150 V6 4.2L and other vehicles measures the oxygen in the exhaust gas. That reading shows how efficiently the fuel is burning in the engine.
- Made for its specific application and fitting position, with the diagnostic feedback the ECU requires
- Coating protects the electrode surfaces from combustion residue and particulates in the exhaust gases
- Electrodes made of a gas-permeable platinum layer
- Monitors exhaust gases to help reduce pollutants
- Oxygen readings help fine-tune the air-fuel ratio for fuel economy
Quick facts
- Part: Walker Products 350-34691 oxygen sensor
- Fits: the 2000-2008 Ford F-150 V8 5.4L, the 2004-2008 F-150 V8 4.6L, the 2005-2008 F-150 V6 4.2L and other vehicles
- Position: Upstream
- Condition: New
A failing sensor might make the engine run poorly, raise fuel consumption and exhaust emissions, or light the malfunction indicator light. These signs alone do not prove the sensor is at fault; a damaged wiring harness or connector can produce them too.
Fits
Beyond the trucks named above, this is an oxygen sensor for the 2004-2010 Ford Explorer V6 4.0L or V8 4.6L and for the 2001-2005 Ford Ranger V6 3.0L and the 2001-2011 Ranger 4-cylinder 2.3L. The listing is one sensor, and the fitment calls for a quantity of one for each application. If your vehicle is not named here, look it up by year and engine in the "Vehicles it fits" section.

Frequently Asked Questions
Is this Ford F-150 oxygen sensor right for the 2004-2008 model with the V8 4.6L engine?
Yes. Walker Products 350-34691 is listed for the 2004-2008 Ford F-150 V8 4.6L. For other years and engines, look up your vehicle in the "Vehicles it fits" section.
What thread and wiring does this narrow-band oxygen sensor have?
Walker Products 350-34691 has an M18 - 1.5 thread and four wires, and it is a narrow-band sensor.
What does the coating on this oxygen sensor do?
The coating protects the electrode surfaces from contamination and erosion by combustion residue and particulates in the exhaust gases. The electrodes are made of a gas-permeable platinum layer.
Is this an upstream oxygen sensor?
Yes. Walker Products 350-34691 is listed as an upstream sensor, and the fitment shows a quantity of one for each application.
Does a failing oxygen sensor store a fault code?
Newer vehicles store fault codes in the ECU, and some of them relate to the affected sensor and its associated systems. A shop can read those codes to help find the cause.
