Circuit Description

Throttle position signal is used by Accelerator and Servo control Module (ASM) to control actual throttle position 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 when EBCM detects a difference between PCM throttle position and throttle position sent from ASM.
