Follow The MAP Sensor

In this article, I want to introduce you to the seldom-used diagnostic power of the Manifold Absolute Pressure (MAP) sensor. A tech asked me to come by and look at a Dodge 1500 pickup with a P0305 code that indicated a cylinder 5 misfire. The tech’s primary tool was a code reader. His question was, is there a quick way to determine which direction to take in the diagnostic procedure?
