My son has an 06 1500 with a 4.7 liter engine. Last night on the way home from work the oil pressure gage dropped to zero,he got no low oil pressure light or check engine light. He stopped and checked his oil and it was full.When he restarted the engine the oil pressure gage came back up and read a little higher than usual.Has anyone had a problem like this and if so what was the problem?I am assuming that it is a problem with the gage itself since he got no check engine or oil pressue lights and the engine continued to run fine.He also said that the outside temperature display went to zero and then returned to normal a couple of nights before the oil gage problem.Are there any known electrical connection problems possibly with the ECM.Any help would be appreciated. Thanks
