RX7 2RTR-1308cc 1.3L MFI (1991)
Control Module: Description and Operation
The EC-AT (Electronically Controlled Automatic Transaxle) control unit, located under the right side kick panel, provides the ECU with a signal
indicating that the transmission is in either "P" or "N" range. The EC-AT control unit receives gear position input from the inhibitor switch. This input
is factored into ECU calculations for outputs such as:
Fuel injection quantity
A/C relay/cut-off
EGR system control
AWS solenoid valve
Pressure regulator solenoid valve
BAC solenoid valve
6PI solenoid valve
Ignition timing control
