Walker Products 350-34066 oxygen sensor for the 2001-2007 Ford Courier 4-cylinder 1.6L, the 2008-2012 Courier and other vehicles measures the oxygen left in the exhaust gas. The 4-wire, narrow-band sensor is made for its specific application and position.
- Electrodes coated with a gas-permeable platinum layer
- Monitors exhaust gases to help reduce pollutants
- Determines the oxygen content of the exhaust gas and monitors the air-fuel ratio for combustion efficiency
- Measures oxygen levels so the air-fuel mixture can be fine-tuned, which helps fuel economy
- Coating protects the electrode surfaces from contamination and erosion by combustion residue and particulates in the exhaust gases
Quick facts
- Part: Walker Products 350-34066 oxygen sensor
- Fits: the 2001-2007 Ford Courier 4-cylinder 1.6L, the 2008-2012 Courier and other vehicles
- Position: Upstream
- Condition: New
A failing sensor can show up as rough running, higher fuel use, more exhaust emissions or a lit malfunction indicator light. These signs alone do not prove the sensor is the problem, since a vacuum leak can also make an engine run poorly. Newer vehicles store fault codes, and the sensor, wiring harness and connector can be checked for physical damage.
Fits
This upstream oxygen sensor fits the 2001-2007 Ford Courier 4-cylinder 1.6L and the 2008-2012 Courier, and it is also an oxygen sensor for the 1995-1999 Ford Contour 4-cylinder 2.0L. This listing is a single sensor, and these cars need just one. If your car is not named here, look it up in the "Vehicles it fits" section.

Frequently Asked Questions
Is this the right oxygen sensor for the 2001 Ford Ka 4-cylinder 1.6L?
Yes. Walker Products 350-34066 is an upstream oxygen sensor for the 2001 Ford Ka 4-cylinder 1.6L, and that car takes one.
What thread size and wire count does the Walker Products 350-34066 have?
The Walker Products 350-34066 has an M18 - 1.5 thread and 4 wires, and it is a narrow-band sensor.
Is this oxygen sensor an upstream or downstream sensor?
This oxygen sensor is an upstream sensor, and Walker Products builds each part number for its specific application and fitment position.
Can a worn upstream oxygen sensor raise fuel consumption?
Yes, a failed sensor can make the engine run poorly, raise fuel use or emissions, or light the malfunction indicator light. A shop can read the stored fault codes.
What is the platinum layer on this Walker oxygen sensor for?
On the Walker Products 350-34066, the electrodes are coated with a gas-permeable platinum layer. The coating keeps combustion residue and particulates in the exhaust from contaminating or eroding the electrode surfaces.
