Overview The idle regulation stepper motor is mounted on the end of the inlet manifold or on the throttle housing; it is controlled electrically by the ECU. This stepper motor controls an air flow taken in parallel to the throttle with the aim of: • providing an additional air flow (cold starting), • regulating an idle speed as a function of...

The ECU is responsible for controlling the "coolant temperature warning" LED when the temperature reaches a critical level (risk of damaging the engine). To perform this function, a coolant temperature thermocontact switch is used. This is mounted directly into the engine block as it can be more reactive in the event of loss of coolant. The...

The coolant temperature sensor has two functions: • it informs the ECU of the coolant temperature in the cooling circuit and therefore the temperature of the engine, • it transmits the coolant temperature information to the temperature gauge on the control panel for non multiplexed vehicles. The ECU uses the coolant temperature...
