DTC P00F3 Alfa Romeo
Humidity Sensor Circuit Range Performance
Humidity Sensor Circuit Range Performance
Description
The Powertrain Control Module (PCM) uses a modeled value from Intake O2 Sensor and the actual Intake O2 Sensor value and compaires that to the Humidity Sensor Signal value. If the Humidity Sensor Signal value is beyond a calabrated threshold a DTC will set. NOTE The Mass Air Flow (MAF) Sensor is combined with the Inlet Air Pressure (IAP) Sensor, Intake Air Temperature (IAT) Sensor 2 and the Humidity Sensor.
Cause and Solution
Humidity Sensor Signal Circuit High Resistance
5-Volt Supply Circuit High Resistance
Sensor Ground Circuit High Resistance
Mass Air Flow Sensor
