Code P00F5 2014 Chevrolet Silverado Description

The Intake Air Humidity Sensor measures the ambient humidity of the air in the sensor bore. The signal varies with intake air humidity and is displayed by the scan tool as duty cycle %. The Engine Control Module (ECM) applies 5 V to the circuit. The signal circuit is shared by the humidity sensor and the Intake Air Temperature (IAT) sensor 2. Ignition voltage and ground circuits are also supplied to the multifunction intake air sensor's internal circuits for these sensors: IAT sensor 2, Humidity sensor, and MAF sensor. The Diagnostic Trouble Code (DTC) will be set when the ECM detects that the humidity sensor signal is greater than or equal to 95 % for greater than 5 s.
