Walker Products 350-34010 oxygen sensor for the 1993-1995 Volkswagen Jetta 4-cylinder 2.0L, the 1994 Jetta V6 2.8L, the 1995-1998 Jetta 4-cylinder 1.8L and other vehicles measures the oxygen in the exhaust gas to show how efficiently the engine burns fuel. This upstream, 4-wire narrow-band sensor is made for its specific application and fitment position, and it gives the ECU the diagnostic feedback it expects.
- Coating protects the electrode surfaces from contamination and erosion by combustion residue and particulates
- Determines the oxygen content of the exhaust gas to monitor the air-fuel ratio
- Monitors exhaust gases and helps reduce pollutants
- Electrodes coated with a gas-permeable platinum layer
- Measures oxygen levels so the air-fuel mixture can be fine-tuned, which supports fuel economy
Quick facts
- Part: Walker Products 350-34010 oxygen sensor
- Fits: the 1993-1995 Volkswagen Jetta 4-cylinder 2.0L, the 1994 Jetta V6 2.8L, the 1995-1998 Jetta 4-cylinder 1.8L and other vehicles
- Position: Upstream
- Condition: New
A rough-running engine, higher fuel use, more exhaust emissions or a lit check engine light can mean this sensor is worn, though the wiring harness or the connector can be behind the same signs and should be checked for physical damage. This listing is one sensor, and the 1993-1995 Volkswagen Jetta 4-cylinder 2.0L takes one.
Fits
The 1993-1995 Volkswagen Passat V6 2.8L and the 1993-1995 Volkswagen Golf 4-cylinder 2.0L take it too, so it works as a Passat oxygen sensor and a VW Golf oxygen sensor, along with many other vehicles.

Frequently Asked Questions
Is this oxygen sensor right for a 1993-1995 VW Jetta 4-cylinder 2.0L?
Yes. Walker Products 350-34010 fits the 1993-1995 Volkswagen Jetta 4-cylinder 2.0L, the 1994 Jetta V6 2.8L and the 1995-1998 Jetta 4-cylinder 1.8L. For any other car, look it up in the "Vehicles it fits" section.
Is this a narrow-band or a wideband oxygen sensor?
Walker Products 350-34010 is a narrow-band sensor with four wires and an M18 - 1.5 thread.
Is this oxygen sensor upstream or downstream?
This oxygen sensor is an upstream sensor. It reads the oxygen content of the exhaust gas so the ECU can follow the air-fuel ratio.
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 also carry a gas-permeable platinum layer.
Does Walker Products 350-34010 interchange with CTK-OSVW4002?
Yes. CTK-OSVW4002 is listed as an interchange number for Walker Products 350-34010.
