I am trying to find the location of the MAP Sensor on a cadillac catera with a 3.0 lit engine.
My car has 35000 miles.
My car has an automatic transmission.
Hi There, The MAP (Manifold Absolute Pressure) sensor should be located just in front of the throttle position sensor toward the back of the left side of the engine (assuming you are standing in front of it facing it). If you have access to a volt meter, I would recommend testing it for power. It should read ~1.5 volts on the return signal green wire and ~4.5 volts and wide open throttle. If this checks out fine, then this likely points to a vacuum leak.
