P1753 ACURA, HONDA, ISUZU: PROBLEM IN TORQUE CONVERTER CLUTCH SOLENOID VALVE CIRCUIT
The Powertrain Control Module (PCM) is responsible for monitoring the vehicle’s systems to ensure that they are all functioning properly. In the case of the transmission system, there is the Torque Converter Clutch (TCC) solenoid, which is controlled to prevent the A/T (Automatic Transmission) from locking. Once this solenoid is activated, hydraulic pressure is applied to the TCC and the transmission lockup is canceled, with the deactivation of the solenoid the hydraulic pressure to the clutch is interrupted and the transmission lockup is allowed.
The PCM controls the TCC solenoid. The controller circuit has the function of diagnosing the valve. It detects and outputs the status of an open or shorted circuit and sends a return signal to the PCM accordingly. The P1753 OBDII fault code is set when the return signal during the PCM command is not appropriate, which is why the PCM interprets this condition as a malfunction.
P1753 OBD2 diagnostic code is set for one of the following reasons:
To troubleshoot the DTC P1753 OBDII code you must do the following:
