                                                      How many ohms should a oil pressure sensor have?

                                                      The reading at zero PSI before starting the engine should be 240 ohms. When you start the engine and bring the oil pressure to 40 psi, this should give you a reading of 103 ohms. Increasing the pressure to 80 psi should give you a reading of 33.5 ohms.

                                                      Is the oil pressure switch and sender the same thing?

                                                      An oil pressure sending unit is also known as an oil pressure switch or even an oil pressure sensor. Oil pressure sending unit is a less common name for the component these days. No matter what the part is referred to, all three serve the safety purpose of monitoring your oil pressure.

                                                      How does a 2 wire oil pressure switch work?

                                                      2 Pin Switch, With One Pin as Ground (Most Common) One on the pin and the other through the body to the engine block. This connection through the body of the switch to the engine block acts as an earth connection. The pin then changes state. Normally the circuit is closed when the oil pressure is low.
