Q: What does code P1107 mean?

MAP Sensor Voltage Intermittent Low. P1107 on a GM vehicle means the powertrain control module (PCM) has detected an intermittent low voltage signal from the manifold absolute pressure (MAP) sensor circuit. The PCM expects the MAP sensor to report a smooth, changing voltage that corresponds to engine vacuum and barometric pressure, but it has seen the signal drop below the expected threshold in a fleeting, non-continuous manner.
