What Does Code P0743 Mean? OBD II fault code P0743 is a generic code that is defined as “Torque converter clutch (TCC) solenoid –electrical”, and is set when the PCM (Powertrain Control Module) detects an abnormal voltage in the electrical control circuit of the TTC ( T orque C onverter C lutch) solenoid.

What causes a torque converter clutch code p0743?

Some common causes of code P0743 could include the following- Damaged, burnt, shorted, disconnected, or corroded wiring and/or connectors Defective TTC solenoid Dirty, contaminated, or degraded transmission fluid that prevents proper operation of the TTC solenoid. Failed or failing PCM or TCM.

What does error code p0743 mean on a Honda Accord?

Error Code P0743 is defined as Torque Converter Clutch (TCC) Solenoid Circuit Electrical. This means the PCM (powertrain control module, also known as ECM or engine control module in other vehicle makes) is seeing a fault in the TCC, which is contained inside…

When to set p0740 code for clutch solenoid?

Once the module deems conditions are correct, it commands one or more TCC solenoid valves to engage the TCC clutch. On most vehicles, the module will set a P0740 code when it detects an electrical fault with the TCC solenoid or the TCC control circuit.

What does the DTC code p0743 stand for?

Diagnostic trouble code (DTC) P0743 stands for “Torque Converter Clutch Solenoid Circuit Electrical.” It is set when the PCM detects a potential issue with the torque converter clutch (TCC) solenoid or its circuit. The torque converter is equipped with a TCC that creates a ‘mechanical lock’ between the engine and the transmission.
