What does torque converter clutch circuit intermittent mean?
When the ECU stores a P0744 diagnostic trouble code, it means the ECU isn’t able to be in full control of the torque convertor clutch.
What causes a torque converter clutch code p0744?
Nonetheless, some common causes of code P0744 could include the following- Damaged, burnt, shorted, disconnected, or corroded wiring and or connectors in the affected control circuit
What is the diagnostic code for torque converter clutch circuit intermittent?
P0744 is a diagnostic trouble code (DTC) for “Torque Converter Clutch Circuit Intermittent”.
What does the p0744 code on a PCM mean?
If the PCM has stored the P0744 code, it means that there was an intermittent abnormality detected in the torque converter clutch circuit.
How is the torque converter clutch solenoid valve activated?
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.
Why is my torque converter clutch code p0744?
The P0744 code is primarily set by mechanical faults such as sticking Torque Converter Clutch (TCC) solenoid or valves in valve body. Since the problem continues after you replaced the transmission fluid, then you may have a problem with the Transmission Valve Body.
When do I get a p0744 on my car?
The P0744 is detected when A/T cannot perform lock-up even if electrical circuit is good. 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 ).
