Keep an accurate watch on engine oil pressure with the Standard Ignition Engine Oil Pressure Sender With Light, MPN PS-311. It drops in as a direct-fit replacement for the 2000-2003 Ford Windstar, the 2004-2007 Ford Freestar, and the 2004-2007 Mercury Monterey (all engines), reading engine oil pressure and relaying it to the vehicle's data monitoring system to operate the oil pressure warning light.

  • High-temperature polyimide film diaphragm: built to resist rupture and oil leakage and to handle rapid pressure pulsations without component damage, for exceptional cycle durability.
  • Accurate signal: engineered to deliver a highly accurate, timely oil pressure reading to the vehicle's data monitoring system.
  • Plug-in fit: a single male blade terminal mates with a female connector, matching the original for easy installation.
  • 100% tested: each unit is tested on vehicles and with automated equipment that activates the switch, checks for leaks, and stresses the part to confirm specification compliance.

If a faulty oil pressure switch is the cause of a warning light that stays on with confirmed-normal oil pressure, this replaces it. Country of origin: Taiwan.
