P0741 Code: Torque Converter Clutch Circuit Performance or Stuck Off
P0741 indicates the torque converter clutch is not engaging properly. Can cause shudder, poor fuel economy and overheating.
What does P0741 mean?
P0741 indicates the torque converter clutch is not engaging properly. Can cause shudder, poor fuel economy and overheating. When this code is set, the engine computer has detected a condition that falls outside its expected parameters for normal operation.
Common causes of P0741
The most frequent causes of a P0741 code fall into four categories:
- Component failure — worn sensors, failed relays, or aging parts that can no longer produce reliable signals.
- Wiring and connectors — corroded pins, chafed wires, or loose ground points that break the signal chain.
- Mechanical issues — vacuum leaks, exhaust leaks, or fuel delivery problems that affect the sensor readings.
- Software and calibration — occasional ECU glitches after battery disconnection or updates.

How to diagnose P0741
- Read the full scan — any codes stored alongside P0741 usually point to the real cause.
- Inspect the most commonly associated components for visible damage or wear.
- Check wiring and connectors for corrosion or breaks.
- Test with a multimeter or scope where relevant.
- Confirm by clearing the code and driving a complete drive cycle.
How serious is P0741?
The severity depends on the underlying cause. In most cases, P0741 doesn't stop the vehicle running — but ignoring it can cause further damage, reduced fuel economy, and failure of a roadworthy or emissions inspection. Get it diagnosed within a few hundred kilometres.
Can I drive with P0741?
Short-term driving is usually fine. Avoid long trips or heavy loads until diagnosed — some underlying faults can escalate to expensive repairs if left unchecked.
