P0108Manifold Absolute Pressure/Barometric Pressure Circuit High Input

The signal voltage from the manifold absolute pressure (MAP) sensor is higher than expected for the conditions. This can mean a wiring short to voltage, a faulty sensor, or a loss of manifold vacuum reaching the sensor. The computer then misreads engine load and may add too much fuel.

Ամենատարածված պատճառներն են՝ Disconnected, blocked, or leaking vacuum line to the MAP sensor, Faulty MAP sensor, Short to voltage in the MAP signal circuit, Wiring or connector fault at the sensor, Mechanical engine problem reducing manifold vacuum։

Check that the vacuum hose to the MAP sensor is connected and clear, then inspect the wiring for shorts to power. Test the sensor signal before replacing it. Driving short distances is generally okay, but fix it soon as running rich can waste fuel and harm the catalytic converter.
