Help your engine's oil pressure warning system get an accurate, timely reading with the Standard Ignition Engine Oil Pressure Switch / Choke Heater Pressure Switch PS638. It is a direct replacement for the 2013-2016 Dodge Dart, 2014-2016 Jeep Cherokee, 2015-2016 Chrysler 200, 2015-2016 Jeep Renegade, 2015-2017 Ram ProMaster City and 2016 Fiat 500X, with every application listed for engine code All. Standard catalogs this part under both names, oil pressure switch and choke heater pressure switch. Each listed application uses one switch.

  • OE fit: Built as a direct replacement with an OE fit, which makes installation easier.
  • Diaphragm construction: Uses high temperature, polyimide film diaphragms. Standard says they provide exceptional cycle durability and resist rupture and oil leakage. The units are designed to handle rapid pressure pulsations without component damage.
  • Accurate readings: Engineered to send a highly accurate and timely oil pressure reading to the vehicle's data monitoring system.
  • 100% tested: Every unit is tested on vehicles and on automated equipment. The equipment activates the switch, checks for leaks and stresses the part to confirm it meets specification.

Connector: One rectangular plug-in connector with three male blade terminals. The color is black and gold. It is sold as the sensor only.

Signs this part may need replacing include an oil pressure warning light that flickers or stays on, an erratic gauge reading, or oil seeping at the switch. Confirm the engine's actual oil pressure before replacing the switch, because a low reading can have other causes.

Country of origin: United States.
