gages... we don't need no stinking cluster gages
 

Ok. if you remember my previous post about my oil pressure gage shorting out
in my '03 2.4 TJ... here's the follow up... and 2 questions near the bottom
of the post
previously: my gage in my dash intermittently would not work, showing
no pressure, then after a few restarts would start working, dealer got in
the jeep turned it on, said "it's working now, bring it back when it's not"
.... damn $tealer... so now that I'm over 36,000 miles, I put a "REAL"
pressure gage on my jeep -
if you want to know where to put an aftermarket pressure gage on the
2.4, on the passenger side, near the back of the engine high on the head
above the exhaust manifold, you will find an 3/16 square hole plug (like a
allen or torx hole but it's square) I ground down an old allen wrench to fit
and unscrewed the plug and the adaptor with the pressure gage fit perfectly
So now that I've got a mechanical pressure gage, and an electronic one
in the dash I can compare the two...
Now to my questions, my electronic gage in my dash never moves, when
its working.... it shows just a tad over half way up on the gage... and it
shows that if my mechanical is reading 25psi or 60 psi.. now I know that
electronic gages are slow to respond to changes, but there are times when
the pressure stays at one level for 10-15 minutes, and still that damn dash
gage reads the same - Does anyone else out there have the 2.4 and does your
oil pressure gage move during normal or abnormal driving or does it behave
just like mine?
Second question - jeep has an idiot light that monitors the dash
gages and when one of them reads abnormal it lights a Check gages idiot
light and beeps at me...
Does anyone know a way to disable this light / beeper, I'm gonna
eventually disable the oil pressure gage in the dash by unplugging the
sending unit and see if the light still goes on, and if that doesn't solve
it, I'm gonna take the light out of the dash - doesn't stop the beeping but
at least I won't have that damn light in my eyes... of course I could just
trouble shoot the oil pressure malfunction - maybe even replace the oil
pressure sending unit, but I don't know that I want to spend the money on
that... especially knowing how useless it is.. ~D
