Oil pressure gauge
3 Answers
First, check your oil level. I the oil level is low, when you turn or go back, inertia pushes it to one side of the engine, when you stop the pump does not pick up enough oil, so pressure does not register on the sending unit. If your oil level is good, then check the pressure sensor sending unit.
