Got P0128 code (Coolant Temp below Thermostat regulating temp) on 2004 Ford Focus ZX3 with 2.3L PZEV Engine. No noticeable change in performance, temperature gauge on dash still functions normally with temperature reading nominal. Where should I start, to figure out the cause of this?
have the same problem?
