Walker Products Oxygen Sensor P/N:250-21024
Walker Products 250-21062 oxygen sensor for the 1989-1991 Dodge Colt 4-cylinder 2.0L and other vehicles measures the oxygen in the exhaust gas so combustion efficiency can be monitored.
A rough-running engine, higher fuel use or a lit malfunction indicator light can mean the sensor is worn, though a damaged wiring harness or connector can be behind the same signs, so look those over for physical damage first. If the sensor is the cause, this one replaces it.
This direct-fit sensor suits the 1989-1991 Dodge Colt 4-cylinder 2.0L and the 1989-1991 Plymouth Colt 4-cylinder 2.0L. This listing is one sensor, and that engine needs one in the upstream position.
Fit and size
Build and materials
Does the Walker Products 250-21062 fit the 1989-1991 Plymouth Colt 4-cylinder 2.0L?
Yes. Walker Products 250-21062 fits the 1989-1991 Plymouth Colt 4-cylinder 2.0L, and it also fits the 1989-1991 Dodge Colt 4-cylinder 2.0L.
Is this Walker Products oxygen sensor an upstream sensor?
Yes. Walker Products 250-21062 is listed for the upstream position and is a narrow-band type of oxygen sensor.
What protects the electrodes on this narrow-band oxygen sensor?
A coating guards the electrode surfaces against contamination and erosion from combustion residue and particulates in the exhaust. The electrodes themselves use a gas-permeable platinum layer.
Can a failing narrow-band oxygen sensor turn on a warning light?
Yes, it can. A failed sensor may illuminate the malfunction indicator light, and newer vehicles store fault codes in the ECU, some relating to the affected sensor and its associated systems.
What feedback does this oxygen sensor give the engine computer?
It determines the oxygen content of the exhaust gas and monitors the air-fuel ratio for combustion efficiency. That gives the ECU the diagnostic feedback it requires for this application.
