Code P0116 2007 Ford Fusion Description

Indicates the engine coolant temperature rationality test has failed. This DTC indicates that the ECT or cylinder head temperature (CHT) value is higher than the calibrated value and could prevent one or more on-board diagnostic (OBD) monitors from completing. The Powertrain Control Module (PCM) runs this logic after an engine off and a calibrated soak period(typically 6 hours). This soak period allows the intake air temperature (IAT) and the CHT or ECT to stabilize and not differ by more than a calibrated value. DTC P0116 sets when all of the following conditions are met: The ECT at engine start exceeds the IAT at engine start by more than a calibrated value, typically 17Â°C (30Â°F).
