Keep an eye on engine lubrication with the Walker Products Engine Oil Pressure Switch 256-1304, an OE-replacement sensor that monitors oil pressure and signals the ECU or dashboard warning light when levels fall below safe operating thresholds. It threads directly into the factory location as a direct-fit replacement for the 1997-1999 Volkswagen Jetta and 1996-1997 Volkswagen Passat — see the Buyer's Guide tab for engine-specific coverage.
Monitors oil pressure: Activates the dashboard warning or ECU input when oil pressure drops below safe operating thresholds.
Early warning function: Alerts the driver or system to low-oil-pressure conditions, helping flag a loss of lubrication before it causes internal damage.
Built for harsh conditions: Made with high-temperature and oil-resistant materials to resist heat, oil exposure, and vibration in demanding engine environments.
OE-replacement calibration: Matches original specifications for pressure activation point, thread pitch, terminal type, and electrical response.
Designed for OE fit, the switch installs in the factory location using the original threads and connectors with no modifications required. Signs the original switch may need replacing include an oil light that flickers, false warnings, or no signal under actual low-pressure conditions. Ideal for scheduled service, a drivability repair, or an engine rebuild.
Frequently Asked Questions
What does this switch do?
