P0107 - Manifold Absolute Pressure/Barometric Pressure Circuit Low

System Information

A Manifold Absolute Pressure Sensor (MAP) is used to measure pressure in the intake manifold. With the ignition on and engine not running this sensor can be used as a barometric pressure sensor to measure atmospheric pressure.

Fault Code Explained

The ECM has detected a sensor value that is below it’s minimum operating parameter or is below what is expected for the current engine operating conditions

Recommended Tests

If possible use a diagnostic computer to read live data to compare sensor values with actual values.
