Walker Products 250-23013 oxygen sensor for the 1991-1992 Volkswagen Jetta 4-cylinder 1.8L and other vehicles measures the oxygen content of the exhaust gas. This upstream Walker Products oxygen sensor sends that reading to the ECU as diagnostic feedback.
- Monitors exhaust gases to help reduce pollutants
- Tracks the air-fuel ratio for combustion efficiency
- Coating protects the electrode surfaces from contamination and erosion by combustion residue and particulates
- Electrodes carry a gas-permeable platinum layer
- Made for one specific application and its position on the vehicle
Quick facts
- Part: Walker Products 250-23013 oxygen sensor
- Fits: 1991-1992 Volkswagen Jetta 4-cylinder 1.8L and other vehicles
- Position: Upstream
- Condition: New
A failing sensor can show up as a poor-running engine, higher fuel consumption, higher exhaust emissions or a lit malfunction indicator light. A damaged wiring harness or connector can also be behind a rough-running engine or a warning light, so look both over for physical damage and track down the cause before you buy a sensor.
Fits
The 1991-1992 Volkswagen Jetta 4-cylinder 1.8L, the 1991-1992 Volkswagen Golf 4-cylinder 1.8L and the 1995 Volkswagen Eurovan 5-cylinder 2.5L all take this sensor, and so do other vehicles. If your car is not one of these, look up its year and engine under the "Vehicles it fits" section.

Frequently Asked Questions
Is this the right oxygen sensor for a 1991-1992 VW Jetta with the 4-cylinder 1.8L?
Yes. Walker Products 250-23013 is listed for the 1991-1992 Volkswagen Jetta 4-cylinder 1.8L, in the upstream position.
Is this a VW Golf oxygen sensor for the 1991-1992 Golf 4-cylinder 1.8L?
Yes. This upstream sensor is listed for the 1991-1992 Volkswagen Golf 4-cylinder 1.8L. The "Vehicles it fits" section covers other cars.
Is this an upstream or downstream oxygen sensor?
Upstream. Walker Products 250-23013 is catalogued for the upstream position.
What thread size does this narrow-band oxygen sensor have?
The thread is M18 - 1.5, and the sensor is a narrow-band, threaded type.
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. The electrodes are made with a gas-permeable platinum layer.
