What does code P2AF5 mean?

Q: What does code P2AF5 mean?

Starter Relay C Stuck On. P2AF5 indicates that the powertrain control module (PCM) has detected the starter relay C circuit is stuck in the energized state, meaning the relay contacts remain closed even when the PCM is not commanding the starter to engage. The PCM monitors the relay control circuit and flags this code when the voltage on the control circuit does not match the expected state, typically seeing voltage present when it should be absent.
