MAP Sensor Code Won't Go Away

Quite a few things can fool the PCM into thinking the MAP sensor has failed when it hasn't.

This is due to the fact that quite a few things can cause the engine to produce low vacuum and set a MAP sensor diagnostic trouble code.

So if the MAP sensor tested good (or you've replaced it) and you're still getting a trouble code for it, then the following testing tips may help you nail down the problem and solution:

  1. Check fuel pump pressure. A failing fuel pump that's not feeding enough fuel to the engine will cause a lean air fuel mixture that can affect engine performance and engine vacuum.
  2. Check that the EGR valve isn't stuck open (if equipped).
  3. Check engine compression of all six cylinders.
  4. Check for vacuum leaks around the intake manifold.
