Walker Products Oxygen Sensor P/N:350-34354
Walker Products 350-34535 oxygen sensor for the 2010-2013 Ford Transit Connect 4-cylinder 2.0L measures the oxygen in the exhaust gas. This Walker Products oxygen sensor is a narrow-band unit that lets the ECU monitor combustion efficiency.
A failing oxygen sensor can show up as rough running, higher fuel consumption, more exhaust emissions or a lit malfunction indicator light. These signs alone do not prove the sensor is at fault, since a vacuum leak can also throw off how the engine runs.
This is a direct-fit replacement for the 2010-2013 Ford Transit Connect 4-cylinder 2.0L, which takes one. This listing is one sensor.
Fit and size
Build and materials
Does the Walker Products 350-34535 oxygen sensor fit the 2010-2013 Ford Transit Connect 4-cylinder 2.0L?
Yes. Walker Products 350-34535 is a direct-fit downstream oxygen sensor for the 2010-2013 Ford Transit Connect 4-cylinder 2.0L, and that engine takes one.
Is this a downstream or an upstream oxygen sensor?
Walker Products 350-34535 is a downstream, narrow-band oxygen sensor. Each part number is made for its specific application and fitment position.
What does the coating on this oxygen sensor do?
The coating prevents contamination and erosion of the electrode surfaces by combustion residue and particulates in the exhaust gases. The electrodes themselves use a gas-permeable platinum layer.
What else should I look at when this oxygen sensor is suspect?
The sensor, wiring harness and connector should also be checked for physical damage, since damage can shorten the sensor's operational life. Do this with the engine off and cool.
Will a failing oxygen sensor set a fault code?
Yes, on newer vehicles: the ECU stores fault codes, and some relate to the affected sensor and its associated systems. A shop can read those codes to help find the cause.
