Code P1758 1997 Honda Civic Description

The torque converter clutch solenoid valve switches the hydraulic circuit to engage/disengage the torque converter clutch. When the torque converter clutch solenoid valve is turned ON, hydraulic pressure is applied to the torque converter clutch. When the torque converter clutch solenoid valve is turned OFF, hydraulic pressure to the torque converter clutch is interrupted.
The Powertrain Control Module (PCM) controls the torque converter clutch solenoid valve. The driver circuit has a diagnostic function that detects and outputs the state of a short or open circuit, and sends a return signal to the PCM. If the return signal during the PCMÂ’s command is not appropriate, the PCM detects a malfunction and stores a DTC.
