The oil pressure gauge will usually be installed where the oil pressure sensor (sometimes called an oil pressure __ or oil pressure switch)is located. Select one: a. Gauging unit b. Sending unit c. Both A and B d. Neither Anor B

The correct answer is c. Both A and B.<br /><br />The oil pressure gauge is typically installed where the oil pressure sensor or switch is located. This can be either in the gauging unit or the sending unit. The gauging unit is responsible for displaying the oil pressure reading, while the sending unit contains the oil pressure sensor or switch that detects the oil pressure and sends the signal to the gauging unit. Therefore, the oil pressure gauge can be installed in either the gauging unit or the sending unit, making option c the correct answer.
