Correct, you have a MAF sensor (Mass Air Flow like mentioned above), not a MAP sensor (Manifold Absolute Pressure). The MAF sensor is located between your throttle body and your filter. Mine (2008) was located right after the filter (which was right above the TB).
Here's the trouble that I have been having. I recently posted a thread on it and didn't get any more input. I was told that the system too lean bank 1 and 2 were tripped off by a MAP sensor or from a vacuum leak. Included is the entire Thread. I would appreciate any input.
