Code P1768 Honda 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.

Discuss the causes and fixes for P1768 Honda OBDII Code

  • Check the 7.5 amp fuse #15 for the alternator inside the car, that fixed my P1768 Code 1999 Civic DX Hatchback with A/T.

  • Same thing with my acura EL 2000.. that alternator fuse triggered the P1768 transmission Code which is very odd....thx so much.. it was starting getting me nuts with the speedometer needle bouncing and jumping around, hard shifting when parked and accelerating in 4th gear from stop with a blinking Drive light...
