The service engine light came on and  the oil pressure gauge is pegged on High.
  Also the 4wd low light flickers on and off intermittantly.
  Do you think these are sensor issues or something more serious?

the " 4LO " light is caused by a faulty " ATP " switch on the 2004's, see your dealer about that, there is a TSB on it to replace the switch, the oil press gauge im unsure on, i havent heard of anyone with a problem there, id have your dealer check that as well

Thanks man, 
  because the truck is running flawless, and the oil pressure being pegged i think it has to be a sensor. Any other input would be greatly appreciated
