Walker Products 250-22066 oxygen sensor for the 1991-1994 Plymouth Colt 4-cylinder 1.5L, the 1992-1993 Colt 4-cylinder 2.4L, the 1992-1994 Colt 4-cylinder 1.8L and other vehicles measures the oxygen in the exhaust gas to show how efficiently combustion is running. This Walker Products oxygen sensor is a direct-fit, 2-wire narrow-band design for the upstream position.
- Electrodes made of a gas-permeable platinum layer
- Coating protects the electrode surfaces from combustion residue and particulates in the exhaust gases
- Determines the oxygen content of the exhaust gas and monitors the air fuel ratio for combustion efficiency
- Monitors exhaust gases and helps reduce pollutants
- Oxygen readings help fine-tune the air-fuel mixture to support fuel economy
Quick facts
- Part: Walker Products 250-22066 oxygen sensor
- Fits: the 1991-1994 Plymouth Colt 4-cylinder 1.5L, the 1992-1993 Colt 4-cylinder 2.4L, the 1992-1994 Colt 4-cylinder 1.8L and other vehicles
- Position: Upstream
A worn oxygen sensor can show up as rough running, higher fuel consumption, more exhaust emissions or a lit malfunction indicator light. A damaged wiring harness or connector can also be behind those symptoms, so inspect both for physical damage with the engine off and cool before you replace the sensor.
Fits
The sensor also fits the 1991-1994 Eagle Summit 4-cylinder 1.5L, the 1992-1993 Summit 4-cylinder 2.4L, the 1992-1994 Summit 4-cylinder 1.8L, the 1991-1994 Dodge Colt 4-cylinder 1.5L and the 1993-1994 Colt 4-cylinder 1.8L. For any other car, look up your year, model and engine in the "Vehicles it fits" section.

Frequently Asked Questions
Does the Walker Products 250-22066 fit the 1993-1994 Dodge Colt 4-cylinder 1.8L?
Yes, Walker Products 250-22066 is listed for the 1993-1994 Dodge Colt 4-cylinder 1.8L. It is an upstream oxygen sensor, and that car takes one.
Is the Walker Products 250-22066 an upstream sensor?
Yes, Walker Products 250-22066 is an upstream oxygen sensor. It is a 2-wire, direct-fit narrow-band design.
What are the electrodes made of in this oxygen sensor?
The electrodes are made of a gas-permeable platinum layer. A coating protects the electrode surfaces from combustion residue and particulates in the exhaust gases.
What can a failing upstream oxygen sensor cause?
Signs can include rough running, higher fuel consumption, more exhaust emissions or a malfunction indicator light. Newer vehicles also store fault codes in the ECU.
How does the Walker Products 250-22066 tell the engine about combustion?
It measures the amount of oxygen in the exhaust gas, which shows how efficiently combustion is running. Walker Products 250-22066 uses that reading to monitor the air fuel ratio.
