Walker Products 350-34427 oxygen sensor for the 1996 Volkswagen Passat 4-cylinder 2.0L, the 1996-2000 Passat V6 2.8L, the 1998-1999 Passat 4-cylinder 1.8L and other vehicles measures the oxygen in the exhaust gas to show how efficiently the engine burns fuel. It is a direct-fit, heated, narrow-band sensor built for its specific application and position.
- 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
- Monitors exhaust gases and helps reduce pollutants
- Measures oxygen levels to fine-tune the air-fuel mixture and support fuel economy
- Determines the oxygen content of the exhaust gas to monitor the air-fuel ratio for combustion efficiency
Quick facts
- Part: Walker Products 350-34427 oxygen sensor
- Fits: 1996 Volkswagen Passat 4-cylinder 2.0L, the 1996-2000 Passat V6 2.8L, the 1998-1999 Passat 4-cylinder 1.8L and other vehicles
- Position: Upstream, downstream, upstream left, upstream right, upstream rear, upstream front
- Condition: New
A failing sensor can show up as rough running, higher fuel consumption, more exhaust emissions or a lit malfunction indicator light, and damage to the sensor, harness or connector can shorten its life. Other faults can give the same signs, so with the engine off and cool, look the sensor, wiring harness and connector over for physical damage before replacing anything. If the sensor is the cause, this Walker Products oxygen sensor replaces it.
Fits
This sensor fits the 1995-1999 Volkswagen Jetta V6 2.8L, and it works as a VW Golf oxygen sensor for the 1995-1998 Volkswagen Golf V6 2.8L, along with many other Volkswagen and Audi models. Open the "Vehicles it fits" section to check your exact model and engine. This listing is one sensor, and each application takes one at its position.

Frequently Asked Questions
Is this one of the VW Jetta oxygen sensors for the 1995-1999 Volkswagen Jetta V6 2.8L?
Yes. Walker Products 350-34427 is listed for the 1995-1999 Volkswagen Jetta V6 2.8L, and that application takes one sensor. For other engines or models, open the "Vehicles it fits" section and check your exact car.
Can I use this oxygen sensor on a 1998-1999 VW Passat 4-cylinder 1.8L?
Yes. The 1998-1999 Volkswagen Passat 4-cylinder 1.8L is in the fitment for Walker Products 350-34427, and it takes one sensor.
How many wires does this Walker Products oxygen sensor have?
This sensor has four wires and is a heated narrow-band type. It has a rectangular male connector with male spade terminals, 20 wire gauge and a 740 mm harness.
What can a failing narrow-band oxygen sensor cause in the engine?
A failed sensor can make the engine run poorly, raise fuel consumption or exhaust emissions, or turn on the malfunction indicator light. Newer vehicles also store fault codes that a shop can read.
Is CTK-OSVW4003 the same sensor as Walker Products 350-34427?
Yes. CTK-OSVW4003 is listed as an interchange number for the Walker Products 350-34427 oxygen sensor.
