What does the oil pressure sender units do?
The oil pressure of an engine can be an important diagnostic tool for the car owner. If the oil pressure is always too low then it may indicate worn bearings that are letting too much oil through. If the oil pressure drops intermittently and then recovers, especially when going through a corner, it could be telling the driver that his oil level is low. Oil that has been compromised (i.e. by getting water in it from a head gasket leak, etc.) will have a different pressure than normal oil. Any changes from the observed normal oil pressure range should be cause to have a look under the hood. Cold oil will have a different pressure range than oil which is hot as a result of warming the vehicle up. This is considered normal. The purpose of the oil pressure sender is to sense the oil pressure in an engine and to send this information over electrical wires to a gauge, generally located on the dash panel of a vehicle. In order to measure the oil pressure, the sender must be exposed directly to the pressurized oil. Engines generally have a threaded hole in them which taps into a pressurized oil passage within the engine. The oil pressure sender screws into this hole. If the oil pressure sender is removed and the engine is started, oil will squirt out the hole under pressure. An oil pressure sender generally works by mechanically moving the wiper arm of a rheostat (i.e. a variable resistor) in direct proportion with the pressure applied to the sender. Thus, oil pressure senders are generally larger than other common senders like water temperature. The variable resistor changes the current that is sent to the remote gauge. That current goes through a coil which creates a magnetic field used to deflect the gauge needle. An oil pressure sender should not be confused with an oil pressure switch. The sender sends analog data in the form of varying current to the remote gauge whereas an oil pressure switch is a binary sensor - it is either open or closed. Thus you cannot connect an oil pressure switch to an oil pressure gauge. Only a sender can be connected to the gauge. Oil pressure switches are often used to control so called "idiot lights" on the dashboard. When the oil pressure gets below a certain level the oil pressure switch closes thus providing a ground to the indicator light or other circuit that is monitoring the switch.
