Question about 1997 Jeep Grand Cherokee
Message center reads coolant sensor bad
This problem is frecuently in this models, check the levels, check and clean the plug connections and Reset your ECU.
Also, can reviewthe #8 wire in a ribbon connector, the factory that made the VIC's use awave soldering method, and the #8 pin (which is the coolant sensorground pin -IIRC it's pink- will have a cold solder joint.
If you cansee faults in this connections, it takes about 15 minutes to get the VICout of the car, and if you cansolder, another 5 to fix the problem. I'dadvise re-soldering all the connections, while you're in there.
If the problem stay there, just change your coolant sensor.
Good luck, and remember rated this help.
