What is the P0741 fault code? What does it signify?
P0741 is an OBD-II common code that can be found on many makes and models of vehicles. This particular code refers to the torque converter clutch/solenoid (TCC), in the automatic transaxle system. The Code is triggered by the Engine Control Module (ECU), when it detects a problem in the torque converter clutch operation.
If the Powertrain Control Module / ECM/ ECU detects more that 200 revolutions per hour (RPM) between the torque conversion rotational speed (TCM) and the input shaft of the transmission, fault code P0741 is set. The rotational speed between the transmission shaft and torque converter should be equal when the torque converter lockup system is activated. If the ratio is not equal, it means that the torque converter lock-up system has failed to achieve the required 1:1 ratio. If the PCM does not illuminate, it will generate code P0741. This code indicates that there is a problem in the torque converter clutch circuit.
Additional Fault Codes
P0740: Torque Converter Clutch (TCC) Circuit Malfunction
P0742: Torque Converter Clutch Circuit Stuck
P0743: Torque Converter Clutch Solenoid Circuit Electrical
P0744: Torque Converter Clutch Circuit Ranges
P2769: Torque Converter Clutch Circuit Low
P2770: Torque Converter Clutch Circuit High
What is the P0741 Fault Code?
- – Defective clutch
- – Defective torque converter lock-up solenoid
- – Defective torque converter
- – TCC solenoid – Internal short circuit
- – Wiring to TCC solenoid damaged
- – Defective valve body
- – Defective Transmission Control Module (TCM)
- Sensor for Defective Engine Coolant Temperatures (ECT).
- – Damage to wiring harnesses in the gearbox
- – Oil with low or no transmission
What are the symptoms for P0741 Malfunction Code?
- – Turn on the engine light
- – An increase in fuel consumption
- – The gearbox is overheated
- – Engine misfires-like conditions
- – Inability or unwillingness to shift gears at high speeds
- – Stopping at high speeds
- – Increased engine speeds
- – Vehicle vibration at certain speeds
- Flashing overspeed light
- – Rarely, symptoms may not be present
How do I fix the P0741 fault code?
Advanced tools will be required to diagnose your vehicle’s torque conversion clutch system. It is important to first take note of all codes in the PCM, then clear them and drive it to check if code P0741 comes back. If the code is not returning:
- Check the transmission wiring harness for loose or damaged connections.
- – Check the relays and fuses that are connected to the gearbox.
- – Check for short circuits in the transmission, clutch, TCC solenoid and TCC solenoid harness.
- – The solenoid or wiring should be replaced if there is a short.
Fault code P0741 can be difficult to diagnose. It is essential to inspect all transmission wiring, transmission controller module (TCM), as well as TCC solenoids. It is a common error to simply replace the torque converter without inspecting them.
What are the Fixes?
- – Replacing solenoid for torque converter lock-up
- – TCC solenoid replacement
- Repairing damaged wires to the TCC solenoid
- – Replacing valve body
- – TCM substitute
- Repair of the damaged wiring in your transmission wiring harness
- – Torque converter replacement
- – Replacing ECT sensor
- – In certain cases, the transmission can be replaced.
What is the importance of the P0741 Fault Code
Fault code P0741 stops the transmission from functioning properly. Other transmission parts may be damaged if you drive in this condition. This fault code P0741 should be addressed immediately.
