DTC P1188 Alfa Romeo
Inlet Air Pressure Sensor Circuit Range Performance
Inlet Air Pressure Sensor Circuit Range Performance
Description
The Powertrain Control Module (PCM) compares the difference between the Inlet Air Pressure to the Manifold Air Pressure, Barometric Pressure, and the Air Boost Pressure. The DTC will set if the Intake Air Pressure differs greater than a calibrated threshold. 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
Iap Signal Circuit High Resistance
5-Volt Supply Circuit High Resistance
Sensor Ground Circuit High Resistance
Mass Air Flow Sensor
