Keep the dashboard oil-pressure warning system working the way it should with the Standard Ignition Engine Oil Pressure Switch PS-314. This direct-fit switch installs in place of the original unit across a long list of Ford trucks and vans, from the 1999 Ford Econoline Super Duty to the F-650 and F-750 medium-duty chassis.

  • What it does: Reads engine oil pressure and switches the electrical circuit that drives the oil-pressure warning lamp or gauge, giving the driver a real-time indication of the lubrication system's status.
  • Direct-fit replacement: Installs in place of the factory oil pressure switch on the listed Ford applications.
  • Signs this part may need replacing: an oil-pressure warning light that stays on or flickers when pressure is actually normal, an erratic or dead gauge, or oil seeping from the switch body. Diagnose the cause first — low readings can also come from the oil pump, oil level, or wiring.
  • Sold individually.

Frequently Asked Questions

What does the PS-314 oil pressure switch do?

It senses engine oil pressure and opens or closes the circuit that operates your oil-pressure warning light or gauge, so the dashboard can indicate the state of the engine's lubrication system.

How do I know if my oil pressure switch is failing?

Common signs include a warning light that stays on or flickers when pressure is normal, an erratic or non-working gauge, or oil weeping from the switch. Diagnose the cause before replacing.

Will this fit my Ford truck?

It's a direct-fit replacement for the listed Ford applications, including E-350/F-250/F-350/F-450/F-550 Super Duty (1999-2010), Excursion (2000-2005), and F-650/F-750 (2000-2007). Check the Buyer's Guide tab.

What numbers does the PS-314 replace?

It interchanges with S4227, 80018, PS404, OP6222, F75F9278CB, F81Z9278AA, SW5267, and 1831259C91.

Does replacing this switch fix low oil pressure?

No. The switch only reports pressure — it doesn't create it. If the switch is faulty, replacing it restores accurate warning and gauge signals, but true low pressure needs separate diagnosis (pump, level, wiring).
