Jeep Grand Cherokee straight 6 1997. My information center keeps telling me my coolant sensor is bad. I replaced the coolant sensor with two different new sensors and it still keeps beeping at me. Truck does not overheat or anything, just keeps telling me coolant sensor bad. Can anyone help me out with this? thanks so much.

You'll have to look around on some of the jeep forums for exact details on how to remove the VIC, but the problem is the #8 wire in a ribbon connector that holds the two VIC circuit boards together. One is the "brain", and the other is the display, and interface.They go together in the VIC "box" like a sandwhich, with the ribbon cable in between.

The factory that made the VICs use a wave soldering method, and the #8 pin (which is the coolant sensor ground pin- IIRC it's pink- will have a cold solder joint.

It takes about 15 minutes to get the VIC out of the car, and if you can solder, another 5 to fix the problem. I'd advise re-soldering all the connections, while you're in there.

OR, buy a used VIC off of someone on E-Bay. The problem with that is they might have the same affliction.
