P100516 — Accelerator pedal sensor 2 supply low
Quick answer
P100516 means the controller reports that the supply to accelerator pedal sensor 2 is out of range on the low side. A pedal sensor fault can limit power, so it should be inspected rather than driven on.
What to check first
- Check the 12 V battery state of charge and terminals; a weak 12 V supply causes many electronic faults.
- Read all stored fault codes with a scan tool and deal with related codes first.
Can I still drive?
Have it inspected before further driving. If in doubt, park the car and ask a technician — a fault that limits power or shuts the high-voltage system down will not clear by itself.
