So it's done it since I've owned the truck, but anyway...Turn the key on: Oil pressure goes to about 40-45psi on the gauge. "Wait a minute.. I haven't even started it.."Stays there, too, after I start it, and drive it. It stays put there, as long as the key is on.. If I unplug the Oil Pressure Switch harness, it goes to zero, so something tells me it's the actual pressure switch?... At the nice price range of $180 (Rock Auto), to $212 at Advance Auto Parts; Auto Zone wants $193 for it.. :nono:Is there something you guys may know about that could be causing this? I mean, something like the 'low oil pressure) TSB, but opposite, obviously.. :)Thanks.
Been trying to get this thing fixed, Went through the grounds and the 1488 and 522 codes keep coming back. Trying to trouble shoot from the book but seems it's just getting more confusing:mad: The book:1488= Auxiliary 5 volt sensor feed is sensed to be below an Acceptable limit. 5-volt Supply Voltage low. Sensor Supply voltage for E C M sensor is too low. book: 522= Oil pressure sending unit voltage input below the min acceptable voltage. Question? is there a sensor that supplies 5 volt's to the E C M?I thought the E C M did the 5 volt thing.:rolleyes:Thanks Ed.
