Walker Products 350-34191 oxygen sensor for the 1997-2002 Mitsubishi Mirage 4-cylinder 1.5L or 1.8L and other vehicles measures the amount of oxygen in the exhaust gas to show how efficiently combustion is running. Each Walker Products oxygen sensor is made for its specific application and fitment position, and it returns the diagnostic feedback the ECU needs.
- Electrodes made of a gas-permeable platinum layer
- Monitors exhaust gases and helps reduce pollutants
- Measures oxygen levels so the air-fuel mixture can be fine-tuned for fuel economy
- Coating protects the electrode surfaces from contamination and erosion by combustion residue and particulates in the exhaust gas
- Narrow-band, 4-wire design
Quick facts
- Part: Walker Products 350-34191 oxygen sensor
- Fits: 1997-2002 Mitsubishi Mirage 4-cylinder 1.5L or 1.8L and other vehicles
- Condition: New
A failed sensor can make the engine run poorly, raise fuel consumption and exhaust emissions, or turn on the malfunction indicator light. Before you replace it, look over the sensor, its wiring harness and the connector for physical damage with the engine off and cool, since damage there can shorten the sensor's life.
Fits
It is also a direct-fit replacement for an oxygen sensor on the 1991-1999 Mitsubishi 3000GT V6 3.0L and the 1991-1996 Dodge Stealth V6 3.0L. This listing is one sensor, and the fitment calls for a single sensor. If your own car is not named here, look it up in the "Vehicles it fits" section by year, make and model.

Frequently Asked Questions
Does this Mitsubishi Mirage oxygen sensor fit the 1997-2002 Mirage 4-cylinder 1.5L or 1.8L?
Yes. Walker Products 350-34191 is a direct-fit oxygen sensor for the 1997-2002 Mitsubishi Mirage 4-cylinder 1.5L or 1.8L. For any other car, use the "Vehicles it fits" section.
Is the Walker Products 350-34191 a narrow-band or wideband sensor?
It is a narrow-band sensor with a 4-wire design. Walker Products 350-34191 determines the oxygen content of the exhaust gas to monitor the air-fuel ratio.
What does the coating on this oxygen sensor's electrodes do?
The electrodes are made of a gas-permeable platinum layer. The coating protects the electrode surfaces from contamination and erosion by combustion residue and particulates in the exhaust gas.
Can a bad oxygen sensor raise fuel consumption?
Yes. A failed sensor can cause rough running, higher fuel consumption, more exhaust emissions or a lit malfunction indicator light. A shop can read the stored fault codes.
Does Walker Products 350-34191 replace CTK-OSCH4004?
Yes. CTK-OSCH4004 is listed as an interchange number for the Walker Products 350-34191 oxygen sensor.
