SYSTEM DESCRIPTION 1. SYSTEM DESCRIPTION (a) The Electronic Controlled Automatic Transmission (ECT) is an automatic transmission that electronically controls shift timing using the Engine Control Module (ECM). The ECM detects electrical signals that indicate engine and driving conditions, and controls the shift point based on driver habits and road conditions. As a result, fuel efficiency and power transmission performance are improved. Shift shock is reduced by controlling the engine and transmission simultaneously. In addition, the ECT has the following features:

DESCRIPTION The Mass Air Flow (MAF) meter is a sensor that measures the amount of air flowing through the throttle valve. The ECM uses this information to determine the fuel injection time and to provide the appropriate air-fuel ratio. Inside the MAF meter, there is a heated platinum wire which is e ...
