  • Page 101 Electronic fuel injection system 4-11 Idle speed control Function: Based on ECU’s information for the engine load, the idle speed actuator is used in controlling the bypass airflow by means of the duration and the frequency (duty factor) of electrical pulse. Idle speed control Principle: The idle sped actuator is composed of electromagnetic coils, armature iron, and valve.
  • Page 102 Electronic fuel injection system Fault diagnosis: ECU is effective in diagnosing both the idle speed control and the driving system. In the event of a short circuit (or overload) between the idle speed controller’s driving system and the battery or a short (open) circuit between the idle speed controller’s driving system and GND, the close loop control for dispensing fuel and the idle air volume learning are terminated but the latest self-learning data is employed.
  • Page 103 Electronic fuel injection system Method for measurement (simplified): Disconnect the connector; turn a multi-meter’s rotary switch to the “Ω” function; connect two probes onto the idle speed controller’s two pins and check if resistance is 26± 4 Ω within the spec. at 20℃. Detectability determination: Check 1: Methods: open the main switch, remove the terminal...

  • Page 105 Electronic fuel injection system B. Ignition check During the idle stage, the ignition angle will make compensation adjustment according to the rotational speed of the engine. When it is lower than the target rotational speed, the ignition angle will be increased so as to increase the rotational speed, on the contrary, when it is higher than the target rotational speed, the ignition angle will be reduced so as to reduce the rotational speed, hence, some distinguished peak values can be neglected first, and only the mean value needs to be observed.
  • Page 106 Electronic fuel injection system Notices for maintenance: Root causes of general troubles: Rustiness or airtight characteristic deteriorated due to any foreign object in the valve. ① Airflow direction conformable to spec. during installation; ② Check and replace the idle speed controller in case of failure of the controller due to some black particles inside the valve;...
