Code P1768 1996 Honda Civic Description

The A/T clutch pressure control solenoid valve is used for shift control and lock-up control. A spool in the A/T clutch pressure control solenoid valve pushes a valve according to the duty cycle that is controlled by the Powertrain Control Module (PCM) to pressurize fluid so the hydraulic pressure is proportional to the current. The PCM measures the current flowing through the A/T clutch pressure control solenoid valve and uses feedback control to compensate the difference between the actual current and the commanded one. If the measured current for the PCM output duty cycle is not within a specified range (open or short to ground), a malfunction is detected and the P1768 code is set.
