Oil Pressure Problems – Gauge, Sensor or what?
What does the gauge read with the key on, engine off? Does it read zero pressure? With the key on, pull the wire off the oil press sender. Does the gauge now drop to zero? If so, short the wire that goes to the press sender to ground. Does the gauge go to the same place it does when the car is running? As a last test, hook a DMM set on a low ohms range between the oil press sensor and ground with the car running. Resistance should be around 5 to 10 ohms, roughly. If it reads zero ohms, sensor is bad. BTW, have you put a real mechanical gauge on it to see what the press really is? Ford had a bunch of complaints about high oil press readings on the factory gauge (in the red at high end of scale)…. their solution. Put a pin in the gauge to keep the needle from ever going into the red!! Back to Top Ranger Fan Conversion by Gary S. email: smitgar@shaw.ca Here is the basic list of things I used.
