First observation I would consider it could be the gage or the wiring either to the gage or from the gage to the sender unit. Probably the easiest in terms of time /expense is using a after market add on gage. Note this may require access to and replacement to the sender unit, but still less work than pulling the dash.

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, [Non-text portions of this message have been removed]
