Walker Products 350-33098 oxygen sensor for the 1986-1991 Volkswagen Vanagon H4 2.1L measures the oxygen in the exhaust gas to track combustion efficiency. This direct-fit, 3-wire narrow-band sensor is made for its specific application and fitment position, and it gives the ECU the diagnostic feedback it needs.

• Reads exhaust oxygen levels to help fine-tune the air-fuel mixture and support normal fuel economy
• Electrodes made of a gas-permeable platinum layer
• Monitors exhaust gases and helps reduce pollutants
• Coating protects the electrode surfaces from contamination and erosion by combustion residue and particulates in the exhaust

Quick facts

• Part: Walker Products 350-33098 oxygen sensor
• Fits: 1986-1991 Volkswagen Vanagon H4 2.1L
• Position: Upstream
• Condition: New

A failing oxygen sensor can show up as an engine that runs poorly, higher fuel consumption, more exhaust emissions or a lit malfunction indicator light. A damaged wiring harness or connector can also make the engine run poorly, so these signs alone do not prove the sensor is the problem. If the sensor is the cause, this one replaces it.

Fits

This sensor fits the 1986-1991 Volkswagen Vanagon H4 2.1L, which takes one. This listing is a single upstream sensor.
