TechASSIST: Product Support and Information

Oil pressure switches serve as an essential safety net in the engine’s lubrication system. A correctly functioning switch: • Monitors engine oil pressure and triggers dashboard warning lights in case of pressure loss • Protects against catastrophic engine failure by alerting the driver early • Supports ECU-controlled features such as start/stop systems, turbo protection, and variable oil pumps • Maintains compliance with safety and emissions regulations by enabling self-diagnostics • Provides redundancy in systems that also include pressure sensors, ensuring layered protection Despite their simplicity, oil pressure switches are a vital line of defence against major engine damage.

Why Do They Fail?

Oil pressure switches endure continuous heat, pressure cycling, and exposure to contaminants. Common causes of failure include:

  • Internal diaphragm wear or rupture, leading to false readings or leaks
  • Oil contamination from sludge or degraded oil causing sluggish or stuck contacts
  • Connector corrosion due to oil seepage or environmental moisture
  • Thread damage or cracking from over-tightening during servicing
  • Incorrect replacement part, resulting in wrong pressure threshold or connector mismatch

Symptoms of a Failed Oil Pressure Switch

  • Oil warning light stays on despite correct oil level and pressure
  • Oil light flickers, especially during idling or cornering
  • Oil leaks around the switch mounting point
  • No oil light at all, even with low oil pressure (dangerous false negative)
  • ECU fault codes such as P0520 (generic oil pressure sensor/switch issue)

Fitting Tips

  1. Always verify actual oil pressure with a mechanical gauge before replacing
  2. Inspect and clean the electrical connector — corrosion is a common issue
  3. Do not overtighten — torque to spec to avoid cracking housings
  4. Replace sealing washers (copper or rubber) as required
  5. Clear fault codes and run engine test to ensure warning system operates correctly
