Air Flow Sensor

This sensor is located in the air stream of the air flow meter, and supplies air volume information to the CU. The CU uses this and other information in regulating the fuel injection rate.

The air flow meter incorporates an air flow measuring plate. The air flow plate opens when the engine draws in air. The plate is connected to a potentiometer. The potentiometer transmits an electrical signal determined by position of the measuring flap, to inform the CU of engine load.

The potentiometer within the air flow meter prevents loss of engine power during sudden acceleration/deceleration by signaling the CU of necessary fuel enrichment requirements.
