Default 1992 Trooper with trouble code 14

My check engine light comes on and stays on after two minutes of driving. When checking for the problem the FLASHING CHECK ENGINE light indicates 14. My Chilton book says the trouble 14, is a shorted coolant sensor circuit. I've also read that this sensor is under the exhaust manifold on right side of engine and in the engine block. I'm told it just sends a signal to the temperature gauge and not the ECM. Is there another coolant sensor I've overlooked? Car runs fine. Can I do a continuity test to ground or between the two wires on the sensor wiring with out disconnecting the wires from the ECM? The Trooper engine is a 3.2L SOHC.

There is an engine coolant sensor that sends a signal to the computer behind the engine by the firewall. It is a little to the right of center. If yours is like mine it can't even be seen with an inspection mirror. There are heater hoses and A/C tubing plus the wiring harness that the wire going to the sensor is in. What an engineering screw up. My valve covers were leaking oil, so I removed the air intake manifold to make the job easier and then replaced the coolant sensor also and what ever else that was needed.
