Walker Products 350-34454 oxygen sensor for the 2003-2006 Mitsubishi Outlander 4-cylinder 2.4L measures the oxygen in the exhaust gas to show how efficiently the engine is burning fuel. It is an upstream, narrow-band, 4-wire sensor that gives the ECU the diagnostic feedback it needs.
- Electrodes made of a gas-permeable platinum layer
- Coating that protects the electrode surfaces from contamination and erosion by combustion residue and particulates in the exhaust
- Determines the oxygen content of the exhaust gas and monitors the air-fuel ratio for combustion efficiency
- Made for its specific application and mounting position on the vehicle
- Measures oxygen levels so the air-fuel mixture can be fine-tuned for fuel economy
Quick facts
- Part: Walker Products 350-34454 oxygen sensor
- Fits: 2003-2006 Mitsubishi Outlander 4-cylinder 2.4L

A worn sensor can show up as rough running, higher fuel consumption or a lit check engine light, though a damaged wiring harness or connector may be behind those signs too, so look both over for physical damage before you replace the sensor.
Fits
This sensor fits the 2003-2006 Mitsubishi Outlander 4-cylinder 2.4L, which takes one upstream sensor. This listing is a single sensor.

Frequently Asked Questions
Does the upstream Walker Products 350-34454 sensor fit the 2003-2006 Mitsubishi Outlander 4-cylinder 2.4L?
Yes. Walker Products 350-34454 is a direct-fit upstream oxygen sensor for the 2003-2006 Mitsubishi Outlander 4-cylinder 2.4L, which takes one.
Is this Walker Products oxygen sensor narrow-band or wideband?
It is narrow-band. This 4-wire direct-fit sensor, Walker Products 350-34454, measures the oxygen content of the exhaust gas to monitor the air-fuel ratio.
What are the electrodes on this oxygen sensor made of?
The electrodes are made of a gas-permeable platinum layer. A coating protects the electrode surfaces from contamination and erosion by combustion residue and particulates in the exhaust.
What can a failing upstream oxygen sensor do to the engine?
It can make the engine run poorly, raise fuel consumption or exhaust emissions, or turn on the check engine light. A shop can read the stored codes to see whether the sensor is involved.
Is CTK-OSMI4004 a cross-reference for this oxygen sensor?
Yes. CTK-OSMI4004 is listed as an interchange number for this 4-wire narrow-band oxygen sensor, Walker Products 350-34454.
