Idle Speed/Throttle Actuator - Electronic: Description and Operation

COLD IDLE KICKER

The cold idle kicker provides an increase in idle speed during cold engine warm up, of up to 1,100 RPM (normally 725 RPM for manual, 690 RPM for auto), for a faster warm-up to operating temperature during extended idle conditions. This is accomplished by the PCM, which monitors the engine oil temperature (EOT) sensor input and adjusts the RPM accordingly, to a maximum of 1,100 RPM.

The idle speed is increased proportionately when the engine oil temperature is less than 70°C (158°F) and the engine has been at idle for more than 2 minutes. Applying the brake pedal, clutch or accelerator pedal deactivates the cold idle kicker and returns the idle speed to 690 RPM.
