P0C2F
Internal Control Module Drive Motor/Generator Engine Speed Sensor Performance
Generic OBD-II
What it means
The engine speed signal used inside the drive motor/generator control module is not performing as expected. The module uses that speed reading to time motor and generator control, so a poor signal can lead it to limit electric drive.
Can I keep driving? Usually yes in the short term, but power may be reduced, so get it read soon.
