Low oil pressure

Purdue_stroker said:

Sometimes if I leave my key on for a few seconds after the glow plugs are done warming it will throw a low oil pressure light. But then it goes away after I cycle the key again or start the truck. Any one else see this? And the other day it did it and threw a check engine light. But the next time I started the truck the light was gone

Probably the oil pressure switch on the top of the hpop resevoir going out. Its a 20$ part. Could clean the terminal really good first and make sure it didnt cone loose from the switch before replacing it.

It's normal, if the key is in the run position with the engine off you do have low oil pressure. Once you start the truck, you'll have oil pressure and the light goes out. Did you check codes for the check engine light? Probably unrelated
