What the P0108 Code Means and How to Fix It
P0108 Code Explained: What It Means, Common Causes, and How to Fix It Quick Summary The P0108 code indicates the engine computer is detecting a MAP sensor signal voltage higher than expected. In plain English, the PCM thinks the engine is under heavy load or wide-open throttle even when it isn’t. That false reading can cause rough idle, black smoke, poor fuel economy, hesitation, hard starting, and even catalytic converter damage if ignored. In my experience, the most common causes of a P0108 code are: • A faulty MAP sensor … Read More
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
