What is the p0743 code on a torque converter?
What is the p0743 code on a torque converter?
This is an electrical problem code. Could be a problem to the harness to the Torque Converter Clutch (TCC) solenoid, the TCC solenoid connector or the TCC solenoid it self. The cost of diagnosing the P0743 code is 1.0 hour of labor.
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…
What causes a TTC solenoid to stop working?
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.
What is the PCM error code p0743?
In the case of Error Code P0743, the PCM is reading higher than 200RPM difference between the rotational speed Torque Converter and the Transmission Input Shaft. When the Torque Converter Lockup Clutch engages, the ratio between the converter RPM and Input shaft RPM must be 1:1.
What does p0743 mean on a torque converter?
P0743 Meaning The Torque Converter Clutch (TCC) solenoid valve is activated, with the gear in D4, by the Transmission Control Module (TCM) in response to signals sent from the vehicle speed and the Engine Control Module (ECM). Lock-up piston operation will then be controlled.
What are the symptoms of a p0741 solenoid?
Some possible symptoms could include the following- 1 Excessive transmission slippage under hard acceleration. 2 Transmission overheating. 3 Harsh shifting. 4 Increased fuel consumption. 5 Depending on the application, other transmission or torque converter clutch codes may be present along with P0741.
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…
What does fault code p0741 in OBD II mean?
What Does Code P0741 Mean? OBD II fault code P0741 is most commonly defined as “ Torque Converter Clutch Circuit Performance” or sometimes as “Torque Converter Clutch- Stuck Off”, and is set when the PCM (Powertrain Control Module) detects an abnormal electrical value in the torque converter clutch control circuit.
