  1. #1

    Default oil sending unit

    where is the oil sending unit at on a gmc sonoma pick up? and will the sending unit go faulty? what causes low oil pressure after running the engine for a while? the oil pressure will drop considerably?

    Hello mckinness632000,

    You should check the actual oil pressure by using a gauge. Generally, you can find related information in Chapter 2 of our manual for your vehicle. It is possible that the oil sending unit or circuit is faulty. Many failures like this are electrical and are caused by high resistance in the circuit somewhere. In other words, a bad connection.
