P0607 Control module performance
What P0607 means
The engine control unit runs internal checks on its own operation and one of them has failed. On some cars this triggers reduced-power mode because the throttle control cannot be fully trusted.
P0607 is a generic SAE J2012 code: it means the same on every make. The exact cause still depends on the car, so read the freeze-frame data before replacing parts.

Can I keep driving with P0607?
You can drive carefully, but have it checked within one to two weeks, sooner if the car enters limp mode.
What to check first
- Test the battery and charging system
- Check ECU grounds and power fuses
- Check for a software update for the control unit
- Replace the control unit if the fault persists
