What does code P2AF8 mean?

Q: What does code P2AF8 mean?

Starter Relay D Control Circuit Low. P2AF8 indicates that the powertrain control module (PCM) has detected a low-voltage condition on the control circuit for starter relay D, which is the relay responsible for engaging the starter motor. The PCM commands the relay by supplying a ground or voltage signal, and when the feedback on that circuit stays below the expected threshold, the code is stored and the starter may not crank.
