billy 2 Posted January 14, 2011 Report Share Posted January 14, 2011 (edited) I have a 2005 Silverado I bought new, The problem is when I turn the ignition on the oil presure gauge will go to 80psi without starting the engine. Is the gauge bad or is it the sending unit? Thanks billy 2 Edited January 14, 2011 by billy 2 (see edit history) Quote Link to comment Share on other sites More sharing options...

svtlightning93 Posted January 14, 2011 Report Share Posted January 14, 2011 More than likely you have a bad stepper motor in the gauge cluster, Quote Link to comment Share on other sites More sharing options...
