Circuit Description

Throttle position signal is used by Accelerator & Servo Module (ASM) to control actual throttle position that is requested by EBCM. EBCM compares delivered throttle position sensor value that is sent from ASM to throttle position sensor value sent from PCM over Class 2 serial data line.

DTC sets if ASM delivers current greater than 18 amps to accelerator control and adjuster for more than three seconds without cable adjuster reaching its desired position.
