Keep an accurate signal flowing to your dash with the Standard Ignition Engine Oil Pressure Switch PS649. This oil pressure switch senses engine oil pressure and reports it to the vehicle's data monitoring system, driving the oil pressure gauge or warning light. It's a direct replacement that ensures OE fit for the 2013-2016 Scion FR-S, 2016 Scion iA, and 2017-2020 Toyota 86 — see the Buyer's Guide tab for engine-level details.

  • Direct-fit design: engineered as a direct replacement for OE fit and straightforward installation.
  • Durable diaphragm: built with high-temperature polyimide film diaphragms for exceptional cycle durability and resistance to rupture and oil leakage, and designed to handle rapid pressure pulsations without component damage.
  • Accurate readings: engineered to deliver a highly accurate, timely oil pressure reading to the vehicle's data monitoring system.
  • Tested for reliability: units are 100% tested on vehicles and with automated equipment that activates the switch, checks for leaks, and stresses the part to verify specification compliance.

If a failed oil pressure switch is behind an erratic gauge or an illuminated oil pressure warning, PS649 replaces it with robust materials that meet the demands of the service professional.

Frequently Asked Questions

What does the PS649 oil pressure switch do?

It senses engine oil pressure and sends that signal to the vehicle's data monitoring system, which drives the oil pressure gauge or warning light on the dash.

Which vehicles does this switch fit?

It's a direct-fit replacement for the 2013-2016 Scion FR-S, 2016 Scion iA, and 2017-2020 Toyota 86. Check the Buyer's Guide tab to confirm fitment for your vehicle.

What are signs this switch may need replacing?

An erratic or dropped oil pressure gauge reading, or an oil pressure warning light, can be signs of a failed switch. Diagnose the cause first, since low oil pressure has other sources.

It cross-references S4640, PS811, OP7640, SU00300523, and SU00306104.

How is this switch built and tested?

It uses a high-temperature polyimide film diaphragm for cycle durability and leak resistance, and each unit is 100% tested on vehicles and automated equipment for specification compliance.
