Keep an accurate oil-pressure signal reaching your gauge or warning lamp with the Standard Ignition Engine Oil Pressure Switch PS759. This switch senses engine oil pressure and reports it to the vehicle's data monitoring system, so the dash gauge or low-pressure warning light reflects what the engine is actually seeing. It's cataloged under both names, so you may also find it listed as a Choke Heater Pressure Switch. Confirm fitment for your vehicle on the Buyer's Guide tab.
- Direct replacement: built to provide an OE fit for straightforward installation.
- High-temperature polyimide film diaphragm: provides exceptional cycle durability and resistance to rupture and oil leakage, and is designed to handle rapid pressure pulsations without component damage.
- Accurate reporting: engineered to deliver a highly accurate, timely oil-pressure reading to the vehicle's data monitoring system.
- 100% tested: checked on vehicles and with automated equipment that activates the switch, checks for leaks, and stresses the part to confirm specification compliance.
Robust design and high-grade materials meet the demands of today's service professional. If a faulty oil pressure switch is behind an erratic gauge reading, a false or missing oil-pressure warning light, or oil seeping from the switch, this replaces it.

Frequently Asked Questions
What does the PS759 oil pressure switch do?
It senses engine oil pressure and sends that signal to the vehicle's data monitoring system, driving the dash oil-pressure gauge or the low-pressure warning light.
Why is it also called a Choke Heater Pressure Switch?
This part is cataloged under both names — Engine Oil Pressure Switch and Choke Heater Pressure Switch — so you may find it listed either way.
What are signs this switch may need replacing?
An erratic or dead oil-pressure gauge, a false or non-illuminating warning light, or oil weeping from the switch. Diagnose the cause first, since these signs can have other sources.
