requests of LIE control units received by CAN lines. The LIEs create these requests according to PA and RPM parameters, and operating strategies at idle and start-up.
Each throttle bodie has a throttle controlled by an actuator that receives opening information from the ETB ECU.
There are 2 feedback potentiometers inside the throttle that read its position in order to diagnose any malfunctioning
of the throttle body and send the information to the ETB ECU (which forwards the information to the 1-5 cylinder bank LIE).
