I am having gauge problems and one may be the oil pressure switch but don't know where it is or looks like and there is supposed to be a sensor on A HEAD BESIDES THE one in the intake for coolant temps. Anyone know where these or even one are located, pic may be helpful. Thanks and many thanks to Chris Jobe for the help he has given. Mark

Thanks for that pic. That will show me where to find that.
There is also a coolant sensor I am also looking fgor and this is supposed to be located in one of the heads. The coolant sending unit on the intake is easy enough but that is for the gauge but there is also one in a head that would help the ECM decside how much fuel is needed along with other info but I did the trip odometer check and came up with both the coolant and oil switch codes. Removed the battery cables overnite nd the oil switch cleared but still get the coolant sensor. Anyone know where that is? Haynes manual does not get very detailed and this sensor seems to be a dealer only part and even the info is dealer accessable until I learned how to do that diagnostic check. By the way I get no cels which seems odd but perhaps the sensor is still working but out of spec? Thanks, mark
