Vehicle is a 1998 accord, 4 cyl, 5 speed, 167000 miles.
Having an issue with the temperature gauge, a few seconds after starting the engine the gauge climbs all the way into the hot range and stays there until car is turned off.
Car is not over heating i drive it 70 miles a day with the gaugelike this and the car runs fine.
Coolent sensor that goes to the ecu has been replaced- didnt solve the gauge problem. Temperature sending unit sensor that controls the gauge has been replaced- didnt solve gauge problem. Ive searched the honda forums with no luck, all i can find is how to test the sending unit sensor, with no explinations of how to fix the issue. There were a few threads about people who swapped gauge clusters but that did not solve it either. I think there is a issue with the wiring that goes from the sending unit to the gauge but i cant find any answers to fix it.
From all of the car forums ive checked out over the years tacomaworld is definitely the most tech savy and helpful so i thought id check here.
