What is the 2003 Mazda Protege map sensor location?

Your 2003 Mazda Protege manifold absolute pressure (MAP) sensor is located attached to Your intake manifold. It's held in place by two screws, and has a wire connector going to it. Switching out is incredibly simple. Cost wise, You can pick up a new one from AutoZone for around $42; brand isn't important. If You haven't had a diagnostic trouble code (DTC) thrown of the check engine light (CEL) illuminated, but suspect there are some issues with the MAP, here are some of the common symptoms: Erratic or rough idling, especially when You've been driving and stop (at a stop light, etc), delay when accelerating or trying to slow down, and excess exhaust emissions (and subsequent failure of an emissions test).
