P0107 Code Explained: MAP and BARO Low Voltage Problems

What Causes the P0107 Code Quick Summary The P0107 code indicates the engine computer is detecting an abnormally low signal from the pressure-sensing system—specifically, a Manifold Absolute Pressure sensor low-voltage input and, in some designs, a related Barometric Pressure sensor voltage input issue. In plain terms, the PCM believes engine load or atmospheric pressure is much lower than it actually is. The most common causes are wiring faults, poor grounds, sensor contamination, or vacuum-related problems—not a bad computer. Accurate diagnosis relies on live data, electrical checks, and vacuum verification. Fix … Read More
