P0108 JAGUAR - Manifold Absolute Pressure/Barometric Pressure Circuit High Input
| Comments | Add Yours |
Possible causes
- Manifold Absolute Pressure harness is open or shorted
- Manifold Absolute Pressure sensor poor electrical circuit connector
- Faulty Manifold Absolute Pressure sensor
- Faulty Powertrain Control Module (PCM) or Engine Control Module (ECM)
- Manifold Absolute Pressure sensor poor electrical circuit connector
- Faulty Manifold Absolute Pressure sensor
- Faulty Powertrain Control Module (PCM) or Engine Control Module (ECM)
When is the code detected?
An excessively high voltage from the sensor is sent to ECM
Symptoms
- Engine Light ON (or Service Engine Soon Warning Light)
- Engine rough idle
- Engine hesitation
- Engine rough idle
- Engine hesitation
P0108 JAGUAR 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
