Walker Products 350-34408 oxygen sensor for the 2008-2010 Mitsubishi Lancer 4-cylinder 2.0L, the 2009-2010 Lancer 4-cylinder 2.4L and other vehicles measures the oxygen in the exhaust gas to track combustion efficiency. Each part number is made for its specific application and position, and gives the ECU the diagnostic feedback it needs.
- Monitors exhaust gases to help reduce pollutants
- Electrodes made of a gas-permeable platinum layer
- Determines the oxygen content of the exhaust gas to monitor the air-fuel ratio
- Coating protects the electrode surfaces from contamination and erosion by combustion residue and particulates
- 4-wire narrow-band design
Quick facts
- Part: Walker Products 350-34408 oxygen sensor
- Fits: the 2008-2010 Mitsubishi Lancer 4-cylinder 2.0L, the 2009-2010 Lancer 4-cylinder 2.4L and other vehicles
- Position: upstream, downstream, upstream right, upstream rear, upstream front
- Condition: New
A failing oxygen sensor can show up as rough running, higher fuel use, more exhaust emissions or a lit check engine light. Before you replace it, rule out physical damage to the wiring harness and connector, since damage there can also shorten a sensor's life.
Fits
The vehicles it fits include the 2001-2012 Dodge Atos and the 2004-2011 Mitsubishi Endeavor V6 3.8L. A 2001-2012 Dodge Atos takes one, and this listing is a single sensor. Driving something else? Look up your car's years and engine in the "Vehicles it fits" section.

Frequently Asked Questions
Is this Lancer oxygen sensor right for the 2008-2010 Mitsubishi Lancer 4-cylinder 2.0L?
Yes. Walker Products 350-34408 fits the 2008-2010 Mitsubishi Lancer 4-cylinder 2.0L, and also the 2009-2010 Lancer 4-cylinder 2.4L.
Is this a Mitsubishi Endeavor oxygen sensor for 2004-2011 models with the V6 3.8L?
Yes. Walker Products 350-34408 fits the 2004-2011 Mitsubishi Endeavor V6 3.8L, which takes one sensor.
Is this 4-wire oxygen sensor narrow-band or wideband?
It is narrow-band. The sensor has four wires and an M18 - 1.5 thread, and its electrodes are made of a gas-permeable platinum layer.
Can a failing oxygen sensor raise fuel use or turn on the check engine light?
Yes, it can. A failed sensor can cause poor engine running, higher fuel consumption, more exhaust emissions or a malfunction indicator light, and newer vehicles may also store a related ECU fault code.
Does CTK-OSCH4007 cross-reference to this oxygen sensor?
Yes. CTK-OSCH4007 is listed as an interchange number for Walker Products 350-34408.
