Chevrolet Monte Carlo MAP sensor failure causing check engine light on Chevrolet Monte Carlo

Some Chevrolet Monte Carlo owners report experiencing issues related to MAP sensor failure, which can lead to the illumination of the check engine light. These issues arise when the MAP sensor, responsible for measuring air pressure in the engine's intake manifold, has a voltage reading that falls outside the normal operating range, typically too high. Common causes of these problems include a faulty MAP sensor, wiring issues, or vacuum leaks. Additionally, factors such as clogging, contamination, damage, or exposure to excessive engine heat can compromise the sensor's electronics or vacuum lines. As a result, owners are advised to address these concerns promptly to avoid further complications.
