P1773 ACURA, HONDA, ISUZU: CLUTCH PRESSURE CONTROL SOLENOID VALVE 'B' CIRCUIT
The solenoid that monitors clutch pressure is used for shift control as well as lock-up control. A spool is located on the solenoid, which actuates the valve based on the duty cycle that is handled by the PCM (Powertrain Control Module). This whole process is performed with the objective of pressurizing the liquid, in order to create a hydraulic pressure proportional to the electrical signal. The Power Train Control Module is in charge of measuring the voltage passing through the pressure control solenoid and consequently adjusts the feedback so that the expected voltage can be compensated with the actual voltage.
The P1773 OBDII fault code is related in certain vehicles to the Clutch Pressure Control Solenoid. In this case, the code indicates that the “B” circuit of the clutch pressure control solenoid has exhibited performance problems.
P1773 OBD2 diagnostic code is set for one of the following reasons:
To troubleshoot the DTC P1773 OBDII code you must do the following:
