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

A failing sensor can show up as a poorly running engine, higher fuel consumption, more exhaust emissions or a lit malfunction indicator light. Those signs alone do not prove the sensor is the problem, since a vacuum leak can cause a rough-running engine too.

Fits

This direct-fit sensor also fits the 1988-1994 Volkswagen Golf 4-cylinder 1.8L and the 1993-1997 Volkswagen Sedan H4 1.6L. Every car it fits takes one upstream sensor, and this listing is a single sensor.
