What does P1582 mean
P1582 indicates the electronic throttle control (ETC) adaptation has not learned properly, affecting throttle response and engine performance.
Common causes of P1582
- Faulty throttle position sensor (TPS) signal
- Intermittent wiring or connector issues in the ETC circuit
- Low battery voltage during relearn attempts
- Faulty electronic throttle body (ETB) motor
- Incomplete relearn procedure after service
What shows on a live scan
During a live scan, you may see related PIDs such as:
- Throttle Position Sensor (TPS) voltage
- Throttle Actuator Control (TAC) motor position
- Throttle Position Sensor (TPS) status
- Throttle Actuator Control (TAC) voltage
- Throttle Position Sensor (TPS) adaptation values
DIY checks for P1582
Check battery voltage to ensure it meets specifications during relearn procedures. Inspect wiring and connectors for damage or corrosion in the ETC circuit. Verify throttle body movement is smooth and unobstructed.
When to see a specialist
If the code persists after basic checks or if relearn procedures fail, consult a specialist to avoid further drivability issues.
FAQ
Can I keep driving with this code
Driving with P1582 may cause rough idle or poor acceleration, so limit driving to short trips and monitor performance.
Will it clear itself
The code may clear if the underlying issue resolves, but incomplete relearn cycles often require manual intervention.
What does the repair usually involve
Repairs typically involve cleaning or replacing throttle components and performing a proper relearn sequence, with costs varying — confirm with a specialist.
If the issue persists, a verified specialist can help resolve it safely.
