Walker Products 350-33073 oxygen sensor for the 1995-1999 Volkswagen Golf 4-cylinder 1.8L and other vehicles measures combustion efficiency from the oxygen in the exhaust gas. This upstream Walker Products oxygen sensor is made for its specific application and fitting position, and it gives the ECU the diagnostic feedback it requires.
- Monitors exhaust gases and reduces pollutants for a cleaner environment
- Monitors the air-fuel ratio from the oxygen content of the exhaust gas
- Measures oxygen levels so the air-fuel mixture can be fine-tuned, which supports fuel economy
- Coating protects the electrode surfaces from contamination and erosion by combustion residue and particulates
- Electrodes with a gas-permeable platinum layer
- Three-wire, narrow-band design
Quick facts
- Part: Walker Products 350-33073 oxygen sensor
- Fits: 1995-1999 Volkswagen Golf 4-cylinder 1.8L and other vehicles
- Position: Upstream
- Condition: New
A rough-running engine, higher fuel consumption or a lit malfunction indicator light can mean the sensor has failed. A damaged wiring harness or connector can be behind the same signs, so find the cause before buying a new sensor.
Fits
It is an oxygen sensor for the 1990-1994 Volkswagen Jetta 4-cylinder 1.8L and the 1991-1993 Volkswagen Passat 4-cylinder 2.0L, among the vehicles it fits. This listing is one sensor, and the 1995-1999 Volkswagen Golf 4-cylinder 1.8L takes one. Driving something else? Look up your year and engine in the "Vehicles it fits" section before you order.

Frequently Asked Questions
Is this one of the VW Jetta oxygen sensors for the 1990-1994 Volkswagen Jetta 4-cylinder 1.8L?
Yes. Walker Products 350-33073 is an upstream oxygen sensor for the 1990-1994 Volkswagen Jetta 4-cylinder 1.8L, and that Jetta takes one.
Is the Walker Products 350-33073 a VW Golf oxygen sensor for the 1995-1999 Volkswagen Golf 4-cylinder 1.8L?
Yes. Walker Products 350-33073 fits the 1995-1999 Volkswagen Golf 4-cylinder 1.8L as its upstream sensor, and the Golf takes one.
Is this upstream oxygen sensor narrow-band or wideband?
This upstream oxygen sensor is narrow-band with three wires. It determines the oxygen content of the exhaust gas to monitor the air-fuel ratio for combustion efficiency.
What should I look at on an upstream oxygen sensor that may be failing?
A failed sensor can show up as poor running, higher fuel consumption or a lit malfunction indicator light. With the engine off and cool, the sensor, wiring harness and connector can be checked for physical damage.
What is the coating on the Walker Products 350-33073 for?
The coating on this oxygen sensor protects the electrode surfaces from contamination and erosion by combustion residue and particulates in the exhaust gas. The electrodes use a gas-permeable platinum layer.
