  Q: How to Service the Mass Air Flow Sensor on Mercury Marauder?

  A: Disconnection of the battery ground cable serves as the first step for servicing the Mass Air Flow (MAF) sensor. Service of MAF sensors must include disconnecting both the sensor electrical connector and the air cleaning outlet tube in non-police vehicles. Proper caution must be observed to protect MAF sensing elements in the airflow bypass because unit failure can occur from physical interference. The MAF sensor module operates as a calibrated unit along with its body and must receive replacement in a single unit. There are four bolts which need to be removed to free the MAF sensor. Follow the safety protocol when removing the MAF sensor electrical connector of police vehicles and detach the MAF sensor with two screws by maintaining the same level of care for the sensing elements. The proper installation of the new MAF sensor requires performing the reverse steps of the removal process.
