Re: P0107 anything to worry. Circuit Description
The Manifold Absolute Pressure (MAP) sensor is mounted to the rear of the intake manifold. The MAP sensor measures the pressure changes within the intake manifold which is an indication of the engine load. The MAP sensor has a 5.0 Volt reference, a ground, and a signal circuit.
The MAP sensor contains a diaphragm which changes the resistance based on pressure. When the manifold pressure is low (high vacuum) the sensor output voltage is low. When the manifold pressure is high (low vacuum) the sensor output voltage is high.
The MAP sensor voltage (depending on altitude) can range from 1.0-1.5 Volts at idle (high vacuum) to 4.0-4.9 Volts at wide open throttle (low vacuum). When the PCM senses a signal voltage lower than the normal operating range of the sensor, this DTC sets.
It goes on to say that an EGR Valve may cause this DTC to set. So, it's sensing low manifold pressure (high vacuum) - I don't know if this is necessarily ok?
