A/T Models Except Metro
On A/T applications, the ECM monitors switch position and receives a voltage signal when transaxle/transmission is in any forward or reverse gear. The ECM uses this input signal to help control of fuel injectors, idle speed control and EGR valve (Storm and Storm GSi models).
NOTE:
On Metro A/T models, gear position signal is received from the A/T module. See A/T MODULE GEAR SIGNAL (METRO A/T MODELS) under INPUT DEVICES.
