I realize this isn't the Blind Mechanics list, but I imagine this
would still be alright.
Here is my problem and feel free to contact me off list if
appropriate. I have a 2001 Jeep Grand Cherokee Limited, so this is the
model with the 4.7 V8.
My problem is there seems to be a short somewhere in the circuit that
controls the oil pressure sensor. I recently had the oil pressure
sending unit replaced by a local garage because I could not get at it
without a lift. So, the mechanic replaced the part I supplied and it
has been fine for a couple of months. Suddenly the damn oil gage has
been doing exactly the same thing it was initially in that it drops to
zero randomly sounding the alarm. I'm very certain after talking to
the same mechanic that if it were the oil pump or barings failing,
there would likely be other indications and considering we can go
several miles before the gauge drops to zero, it is quite possible
there is an issue with the connection or a short somewhere. So,
chasing shorts could be a really ugly task and I'm just looking for
any guidance on where I might be looking for possible issues. I
imagine it could be the gauge itself, but man replacing that would be
a task I am not sure I'd want to take on. I have no idea how to get to
the gauges, which would involve pulling the dash apart and that could
be rather complicated and expensive. At this point I just want to do
the least possible to fix the thing and then get rid of the vehicle.
It seems to be more a pain these days and perhaps it is time to
replace it. That or I'll just ignore the problem until something
really brakes and then just donate the damned thing and buy something
new. As it is I don't think I'm going to get a dealer to agree it
isn't a big deal and gee offer me top dollar on this beast. grin. Any
thoughts appreciated.
tnx,
