EGR Throttle Position Control and Throttle Position Sensor

EXHAUST GAS RECIRCULATION THROTTLE POSITION CONTROL AND THROTTLE POSITION SENSOR

Exhaust Gas Recirculation Throttle Position Actuator And Throttle Position Sensor:

EGR Throttle Position Actuator
The EGR throttle position (EGRTP) actuator modifies the intake airflow from the charge air cooler into the intake manifold. The EGRTP actuator regulates the rotary motion of the throttle plate located within the throttle body. The control of intake airflow provides increased EGR system efficiency with the throttle plate position determined by a signal from the EGRTP sensor.

EGR Throttle Position Sensor
The EGR throttle position (EGRTP) sensor is a potentiometer that provides a feedback signal to the PCM. The input signal is an analog voltage proportional to the rotary position (angle) of a throttle plate located within the throttle body
