Q: What does code P258F mean?

Torque Management Request Output Signal. P258F indicates that the powertrain control module (PCM) has detected a fault in the torque management request output signal circuit, which is used to communicate torque reduction requests to other control modules. The PCM monitors this signal and sets the code when the voltage or message does not match expected values, often due to a wiring or module communication issue.
