Q: What does code P20F8 mean?

Intake Manifold Runner Control Circuit Performance (Bank 1). P20F8 indicates that the powertrain control module (PCM) has detected a performance fault in the intake manifold runner control (IMRC) circuit for bank 1. The PCM commands the IMRC actuator to move the runner flaps and monitors the circuit for expected electrical feedback; when the response falls outside the calibrated range, this code is stored.
