I found no topics found when entering 'GEM' on the 1999 Lincoln Navigator. What is a GEM?: Electronic Engine Controls WARNING
To avoid personal injury and/or vehicle damage, refer to the service precautions at the beginning of this section.
General Information The Engine Management System (EMS) uses several different sensors and actuators to gather and control various emissions and driveability aspects of the vehicle. These may include but are not limited to:

  • FTP - Fuel Tank Pressure Sensor
  • A/F - Air Fuel Ratio Sensor
  • CKP - Crankshaft Position Sensor
  • CMP - Camshaft Position Sensor
  • EGR Valve Position - Exhaust Gas Recirculation Valve Position Sensor
  • HO 2S - Heated Oxygen Sensor
  • IAC - Idle Air Control Valve
  • IAT - Intake Air Temperature Sensor
  • KS - Knock Sensor
  • MAF - Mass Air Flow Sensor
  • TP - Throttle Position Sensor
These sensors provide critical information to the EMS such as, barometric pressure, atmospheric pressure, intake manifold/engine vacuum, fuel tank pressures and changes as the vehicle is operated.
