Walker Products 350-32009 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. The ECU uses that reading to monitor the air-fuel ratio and combustion efficiency, and this is a direct-fit narrow-band sensor.
- Coating protects the electrode surfaces from contamination and erosion by combustion residue and particulates in the exhaust gases
- Electrodes made of a gas-permeable platinum layer
- Measures oxygen levels so the air-fuel mixture can be fine-tuned for fuel economy
- Monitors exhaust gases to help reduce pollutants
Quick facts
- Part: Walker Products 350-32009 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
- Condition: New
A failing sensor can show up as rough running, higher fuel consumption or a lit malfunction indicator light, although other faults produce those symptoms as well. Before you replace it, look over the sensor, its wiring harness and the connector for physical damage, with the engine off and cool.
Fits
The 1991-1994 Eagle Summit 4-cylinder 1.5L, the 1992-1993 Summit 4-cylinder 2.4L and the 1992-1994 Summit 4-cylinder 1.8L all fit this sensor, as do many other vehicles. Driving something else? Run your car through the "Vehicles it fits" section. This listing is a single sensor, and the engine needs one at the upstream position.

Frequently Asked Questions
Does the Walker Products 350-32009 fit a 1991-1994 Plymouth Colt 4-cylinder 1.5L?
Yes. Walker Products 350-32009 fits the 1991-1994 Plymouth Colt 4-cylinder 1.5L, the 1992-1994 Colt 4-cylinder 1.8L and the 1992-1993 Colt 4-cylinder 2.4L.
Is this Walker Products oxygen sensor upstream or downstream?
It is an upstream sensor. Walker Products 350-32009 is listed for the upstream position, and the fitment calls for one per vehicle.
Is this oxygen sensor narrow-band or wideband?
It is narrow-band. This sensor has 2 wires and an M18 - 1.5 thread.
How can I tell if an upstream oxygen sensor is going bad?
Higher fuel consumption, more exhaust emissions or a lit malfunction indicator light can point to a failing sensor, but other faults show up the same way. A shop can read the stored codes.
What does the coating on this oxygen sensor do?
The coating keeps combustion residue and particulates in the exhaust from contaminating or eroding the electrode surfaces, which have a gas-permeable platinum layer.
