7 Symptoms of a Broken MAP Sensor

· MAP sensors fail by getting clogged, contaminated, or damaged. Sometimes, engine heat “overcooks” the MAP sensor's electronics or cracks vacuum lines. If the MAP sensor goes bad, the ECM can’t accurately calculate engine load, which means the air-fuel ratio will become either too rich (more fuel) or too lean (less fuel).

Gas detector - Wikipedia

Semiconductor sensors, also known as metal-oxide-semiconductor sensors (MOS sensors), detect gases by a chemical reaction that takes place when the gas comes in direct contact with the sensor. Tin dioxide is the most common material used in semiconductor sensors, [10] and the electrical resistance in the sensor is decreased when it comes in contact with the monitored gas.

What the Knock Sensor Does & How to Tell When It's Bad

· Leaded gas was outlawed in the mid-'70s, and ignition timing on modern engines is dictated by the engine control computer. Older engines advanced or retarded timing via vacuum and would adjust it according to engine load. On a modern engine, the computer receives information from several sensors, but many engines still feature a knock sensor, usually mounted on the intake manifold or …
