What does torque converter clutch solenoid circuit mean?
Transmission Torque Converter Clutch (TCC) Solenoid: DESCRIPTION. Positioned between the rear of the engine and the front of the transmission is the torque converter. The torque converter is responsible for transmitting the engine’s torque and power to the transmission.
What is shift solenoid D?
The shift solenoid D is part of the transmission system; it helps to manage the transfer of fluids between circuits, and to change transmission gear ratios. This solenoid is directed by the ECM, which monitors the solenoid’s voltage reading to ensure that it is working correctly.
What is the purpose of a torque converter clutch solenoid?
The torque converter clutch solenoid is an electronic component that helps to measure the fluid pressure and regulate how much fluid the lockup clutch receives. If the solenoid is faulty, there won’t be an accurate measure of how much transmission fluid is a need which could lead to abnormal fluid pressures.
What does OBD code p0743 stand for?
OBD-ii Code P0743 definition: 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).
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 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 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.
OBD-ii Code P0743 definition: 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).
When your vehicle’s primary computer ( Powertrain Control Module or PCM) detects a problem in the torque converter, it may log the P0743 error code in your vehicle’s on-board diagnostic system. Here is some information that could help you understand this trouble code better. What Does the P0743 Code Mean?
What should the slip speed be on a p0743?
This can be very helpful in the diagnosis of an intermittent P0743. If the Lockup System is functioning correctly, the Slip Speed value should never be above 50 RPM. Try gently depressing the throttle on a gradual incline above 45 mph. When doing this, the Slip Speed should not increase.
How much does it cost to repair a car p0743?
The auto repair labor rates vary widely across the country, and even within the same city. Most auto repairs shops charge between $75 and $150 per hour. When is the P0743 code detected? By performing a voltage drop test, the Engine Control Module (ECM) detects that the Torque Converter Clutch (TCC) solenoid circuit is open or shorted.
