Our trusted friends have launched a new website named LEMON, which has newer manuals. It also contains all the CHARM manuals.

LEMON is the spiritual successor to CHARM, I recommend you try it!

Operation







OPERATION

Airflow is measured by the mass air flow (MAF) sensor. The MAF sensor contains a heated ceramic element. The ceramic element changes resistance respectively to changes in temperature. Changes in air flow and air density cause the temperature of the ceramic element to fluctuate. A voltage will be produced via the MAF sensor when air is passed through. This voltage correlates to airflow. The change in resistance varies the signal voltage output to the powertrain control module (PCM).
