LINE PRESSURE CONTROL OUTLINE

BME051718880107

• The PCM determines the optimum line pressure and drives the linear-type pressure control solenoid based on input signals in accordance with the vehicle driving conditions including the engine torque (calculated from throttle opening angle, vehicle speed, engine speed, gear position, intake air rate, and other operational parameters). As a result, the line pressure is controlled very accurately and closely.
