Code P0108 2000 Honda Civic Description

The P0108 diagnostic trouble code (DTC) for a 2000 Honda Civic refers to a Manifold Absolute Pressure (MAP) Sensor Circuit High Voltage. The MAP sensor is a key component in the engine control system, as it measures the amount of air entering the engine to determine the appropriate fuel mixture for combustion. When the MAP sensor circuit detects a high voltage, it indicates that the pressure in the intake manifold is higher than expected, which can lead to a variety of performance issues.
