P1743 Fault Code: Understanding The Transmission Torque Converter Clutch Solenoid Circuit
The P1743 fault code refers to a problem with the torque converter clutch solenoid valve. This valve is responsible for engaging the lock-up clutch in the transmission, which creates a 1 to 1 RPM ratio between the input shaft and the torque converter.
However, lock-up operation is not allowed when the automatic transmission fluid temperature is too low. One symptom of this fault code is that when the accelerator pedal is pressed (less than 28) while in lock-up condition, the engine speed should not change abruptly.
If there is a significant jump in engine speed, it indicates that there is no lock-up.
In summary, the P1743 fault code indicates that the torque converter clutch solenoid has failed, preventing the proper engagement of the lock-up clutch in the transmission.
This can result in issues with the RPM ratio and engine speed when the accelerator pedal is pressed.
FAQ
If you see the engine light or service engine soon warning light on, it could be due to fault code P1743. This code can be caused by a few different things, including low transmission fluid level, dirty transmission fluid, a faulty torque converter clutch solenoid valve, issues with the harness or connectors of the solenoid valve, or even a mechanical problem within the transmission itself. To fix this issue, start by checking the possible causes mentioned above. Take a close look at the wiring harness and connectors, checking for any damage or corrosion. Also, inspect the components for any signs of breakage or bending.
