What does code P2315 mean?

Q: What does code P2315 mean?

Ignition Coil 'F' Primary Control Circuit Low. P2315 means the powertrain control module (PCM) has detected an abnormally low voltage on the primary control circuit for ignition coil 'F', which is the low-voltage side that the PCM uses to switch the coil on and off. The PCM monitors this circuit and sets the code when the commanded signal does not match the expected voltage, indicating a short to ground, an open circuit, or a faulty coil driver.
