Signs of a faulty part

If you notice any of the following, the part likely needs replacement:

  • Rough idle or hesitation on acceleration
  • Poor fuel economy

Frequently asked questions

On engines that use MAP rather than a mass airflow sensor as the primary load sensor (or as a backup), an inaccurate reading directly throws off the ECU’s fuel and timing calculations, causing noticeable drivability problems.
