Hi,

My friend purchased a 96 integra ls with 190k miles and one of the problems it has is that the temperature needle always reads at the C bar. I hooked up my obd2 scanner and notice that the coolant temperature was always around 140-150F, which is well below the normal cruising temp of around 180-190F. I am automatically suspecting a stuck open thermostat, however i am also suspecting it could be the ECT sensor that could be reading the temperatures wrong. Also, after driving the car for 20 minutes, the heat when full HOT doesnt get no where near as hot as my 2001 integra LS(hair dryer hot). Idle also seem to be on the high side of about 900-1000.

Is there a way i can test the ECT so that if this part is faulty, I can purchase this part when i purchase the thermostat?

Thanks
