P0625 on Toyota
Generator Field "F" Terminal Circuit Low
P0625 on Toyota vehicles indicates generator field "f" terminal circuit low. Au7o has documented this code across 1 Toyota model — most commonly on RAV4. The control module detected a low-voltage (short-to-ground or open) condition on the generator field 'F' terminal circuit. Signal voltage is below the expected range. Typical repair costs on Toyota range from $400 to $900, depending on the specific model and root cause.
Common Causes of P0625
- •Short to ground in the 'F' terminal circuit
- •Faulty alternator/regulator
- •Damaged or corroded wiring/connectors
- •Poor ground
- •Internal PCM fault

- Alternator / Charging System Failure Triggering 'Charging System Malfunction' Warning and No-Start2013-2020
Owners report premature alternator wear (symptoms often around 50k-70k miles) and 'Charging System Malfunction' warnings on the multi-information display. Causes include worn brushes, a failing voltage regulator, a faulty decoupler pulley (pulley spins while rotor doesn't), or oil/power-steering fluid dripping onto the alternator. A failing alternator undercharges the 12V battery, producing warning lights, dimming, and eventual no-start. (Note: non-hybrid gas models; hybrids charge the 12V via the DC-DC converter.)
