Product Information

Full details

The CI Oil Pressure Switch (XOPS48) is an essential component for automotive enthusiasts and professional mechanics requiring precise engine monitoring. Designed to reliably detect oil pressure fluctuations within the 0.05 bar to 0.15 bar range, it serves as a critical safety sensor to prevent engine damage. While it offers excellent durability and exact fitment specifications, users should ensure their vehicle's specific thread type matches the 1/8 inch BSPT requirement before installation.

Is this a universal part?

It is a compatible replacement part built to automotive standards, but you must verify it fits your specific engine's thread and connector requirements.

Troubleshooting

Oil light remains on after installation

Verify the electrical connection is secure and check for actual low oil pressure using a mechanical gauge.

Oil leaking from the base of the switch

Check if the thread sealant was applied correctly and ensure the unit is tightened to the manufacturer's torque specification.

Pros and Cons

Pros

  • Precise pressure detection range
  • Compact 39 mm length for tight spaces
  • Standardized 1/8 inch BSPT thread
  • High-quality construction for long-term reliability

Cons

  • Specific 1-pin connector requirement
  • Not compatible with engines requiring non-BSPT threads
  • Narrow pressure detection window might not suit all high-performance builds

Setup, Compatibility & Care

Installation requires access to the oil filter housing or the engine block port.

  1. Ensure the engine is cool to prevent oil burns.
  2. Locate the existing switch and disconnect the 1-pin wire harness.
  3. Using a 24 mm wrench, carefully unscrew the old unit.
  4. Apply a small amount of thread sealant (if not pre-applied) to the 1/8 inch BSPT thread of the new XOPS48.
  5. Thread the new switch by hand to avoid cross-threading, then tighten with the wrench.
  6. Reattach the 1-pin connector until it clicks into place.

Keep the unit free of excessive debris and avoid using harsh chemicals on the connector housing during engine bay cleaning.
