Code P1638 MINI Description
The Digital Motor Electronics opens or closes the electromotive throttle actuator electrically. The throttle valve opening angle in the electromotive throttle actuator is monitored by 2 hall effect sensors. The throttle valve is moved by an electric actuator motor. This servomotor is actuated by a pulse-width modulated signal with a frequency of 1000 Hz.
The Digital Motor Electronics diagnosis monitors the throttle valve for freedom of movement. The Diagnostic Trouble Code (DTC) is recognized when the pulse-width modulated signal for activating the throttle valve is above 80 %.
What are the Possible Causes of the DTC P1638 MINI?
- Faulty Electromotive Throttle Actuator
- Electromotive Throttle Actuator harness is open or shorted
- Electromotive Throttle Actuator circuit poor electrical connection
