P0107
Powertrain Codes
P0107 - FORD - Manifold Absolute Pressure/Barometric Pressure Sensor Low Input
Symptoms
- Engine Light ON (or Service Engine Soon Warning Light)
- Engine rough idle
- Engine hesitation
Possible Causes
- Manifold Absolute Pressure harness is open or shorted
- Manifold Absolute Pressure sensor poor electrical circuit connector
- Faulty Manifold Absolute Pressure sensor
- Faulty Engine Control Module (ECM)
When Detected
The ECM has detected a performance fault with the MAP sensor
Description
The Manifold Absolute Pressure (MAP) sensor provides instantaneous manifold pressure information to the engine's Engine Control Module (ECM). The data is used to calculate air density and determine the engine's air mass flow rate, which in turn determines the required fuel metering for optimum combustion. A fuel-injected engine may alternately use a Mass Air Flow (MAF) sensor to detect the intake airflow. A typical configuration employs one or the other, but seldom both.
In some vehicles the absolute pressure sensor is built into ECM.
