Hi,
Experiment this morning, 1 hour drive to work.
upon ignition: temp gauge below 60, ECU 13 degrees.
After approx 5 mins: temp gauge up to 90, ECU only up to 14.
throughout 1 hour journey: temp gauge stays at 90, ECU gradually up to 24.
After journey, decided to put the aircon on, temp gauge still at 90, but ECU rising more rapidly now, to 68...
This make me think the Thermostat is fine, but the CTS is fooked?
