Walker Products 350-31045 oxygen sensor for the 1980 Volkswagen Jetta 4-cylinder 1.6L, the 1981-1984 Jetta 4-cylinder 1.7L, the 1984-1987 Jetta 4-cylinder 1.8L and other vehicles measures the oxygen content of the exhaust gas. This upstream, narrow-band sensor monitors the air-fuel ratio for combustion efficiency and gives the ECU the feedback it expects.
- Coating protects the electrode surfaces from contamination and erosion by combustion residue and particulates in the exhaust gas
- Electrodes made of a gas-permeable platinum layer
- Oxygen readings help fine-tune the air-fuel mixture for fuel economy
- Monitors exhaust gases to help reduce pollutants
- Made for its specific application and fitment position, with the diagnostic feedback the ECU requires
Quick facts
- Part: Walker Products 350-31045 oxygen sensor
- Fits: the 1980 Volkswagen Jetta 4-cylinder 1.6L, the 1981-1984 Jetta 4-cylinder 1.7L, the 1984-1987 Jetta 4-cylinder 1.8L and other vehicles
- Position: Upstream
- Condition: New
A failing sensor can show up as the engine running poorly, higher fuel consumption or a lit malfunction indicator light. Before you replace the sensor, rule out physical damage to its wiring harness and connector, and note that stored fault codes can relate to the sensor and its associated systems.
Fits
This direct-fit upstream oxygen sensor also fits the 1985-1987 Volkswagen Golf 4-cylinder 1.8L and many other vehicles. The 1990-1991 Nissan Stanza 4-cylinder 2.4L is another fit and takes one sensor, which is how this listing is sold. Driving something not named here?

Frequently Asked Questions
Will this oxygen sensor fit a 1984-1987 VW Jetta 4-cylinder 1.8L?
Yes. Walker Products 350-31045 is listed for the 1984-1987 Volkswagen Jetta 4-cylinder 1.8L, with one sensor per car.
Is 350-31045 the right VW Golf oxygen sensor for a 1985-1987 Golf 4-cylinder 1.8L?
Yes. This upstream oxygen sensor is listed for the 1985-1987 Volkswagen Golf 4-cylinder 1.8L. Other cars can be looked up in the "Vehicles it fits" section.
What type of sensor is the Walker Products 350-31045?
Walker Products 350-31045 is a direct-fit, narrow-band upstream oxygen sensor. Its electrodes are made of a gas-permeable platinum layer.
Can a worn upstream oxygen sensor make the engine run poorly?
Yes, it can. A failing sensor can also raise fuel consumption, and a shop can read the stored fault codes.
Does CTK-OSNS1001 interchange with this oxygen sensor?
Yes. CTK-OSNS1001 is listed as an interchange number for Walker Products 350-31045.
