Q: What does code P0C9F mean?

14 Volt Power Module Current Sensor B Circuit High. P0C9F means the 14-volt power module has detected that the current sensor on its 'B' circuit is reporting a higher-than-expected current level, which usually indicates a short to voltage or a faulty sensor signal. The module compares the sensor's output against its expected range and sets this code when the signal stays above the calibrated threshold for a set time.
