On a 1990 Ford F-150 with a 4.9L engine, the temperature gauge sensor, also known as the coolant temperature sensor, is typically located on the engine block near the thermostat housing. It's usually found on the driver's side, threaded into the cylinder head or intake manifold. You can trace the wire harness from the temperature gauge on the dashboard to locate the sensor. Make sure to consult a repair manual for specific details and diagrams.
It sounds like a bad Temperature Sensor or the Gage It's self.
The temperature gage on a 95 Civic can be located on the dash board, assuming this temperature gage is for the heat of the engine. It is usually located near the mileage.
a temperature sensor could be faulty...i have a 1994 legacy and i had the same problem...i replaced the temperature gage sensor and i have no more problems.
There is a sensor located between exhaust manifold #1 and #3 (drivers side). This sensor controls the temp gage in a cars interior.
the coolant temperature sensor is faulty. It will need to be replaced
Gage Academy of Art was created in 1990.

possible bad sending unit, if it has the plastic tip it is more than likely cracked and bad. the new replacement ones should be brass. if not that then maybe loose connection or corrosion in terminals at sensor.
the normally position of needle in temperature gage is a half of gage.
Did you ever get an answers to this question? I have a 1990 740 GL with the same problem?ThanksEngine Coolant Temp. sensor ECT (#1346030), sensor for the ECU, not the sensor for the temp gage, I recommend BOSCHLook under the intake close cylinder #3
the sensor
Check actual engine temperature with a thermometer--if in acceptable range temperature sensor or gauge may be defective
