Dodge Journey: Fuel system

FUEL SYSTEM

  • Fuel System Similar Conditions Window - An indicator that 'Absolute MAP When Fuel Sys Fail' and 'RPM When Fuel Sys Failed' are all in the same range when the failure occurred. Indicated by switching from 'NO' to 'YES'.
  • Absolute MAP When Fuel Sys Fail - The stored MAP reading at the time of failure. Informs the user at what engine load the failure occurred.
  • Absolute MAP - A live reading of engine load to aid the user in accessing the Similar Conditions Window.
  • RPM When Fuel Sys Fail - The stored RPM reading at the time of failure. Informs the user at what engine RPM the failure occurred.
  • Engine RPM - A live reading of engine RPM to aid the user in accessing the Similar Conditions Window.
  • Adaptive Memory Factor - The PCM utilizes both Short Term Compensation and Long Term Adaptive to calculate the Adaptive Memory Factor for total fuel correction.
  • Upstream O2S Volts - A live reading of the Oxygen Sensor to indicate its performance. For example, stuck lean, stuck rich, etc.
  • SCW Time in Window (Similar Conditions Window Time in Window) - A timer used by the PCM that indicates that, after all Similar Conditions have been met, if there has been enough good engine running time in the SCW without failure detected. This timer is used to increment a Good Trip.
  • Fuel System Good Trip Counter - A Trip Counter used to turn OFF the MIL for Fuel System DTCs. To increment a Fuel System Good Trip, the engine must be in the Similar Conditions Window, Adaptive Memory Factor must be less than calibrated threshold and the Adaptive Memory Factor must stay below that threshold for a calibrated amount of time.
  • Test Done This Trip - Indicates that the monitor has already been run and completed during the current trip.

MISFIRE

  • Same Misfire Warm-Up State - Indicates if the misfire occurred when the engine was warmed up (above 160º F).
  • In Similar Misfire Window - An indicator that 'Absolute MAP When Misfire Occurred' and 'RPM When Misfire Occurred' are all in the same range when the failure occurred. Indicated by switching from 'NO' to 'YES'.
  • Absolute MAP When Misfire Occurred - The stored MAP reading at the time of failure. Informs the user at what engine load the failure occurred.
  • Absolute MAP - A live reading of engine load to aid the user in accessing the Similar Conditions Window.
  • RPM When Misfire Occurred - The stored RPM reading at the time of failure. Informs the user at what engine RPM the failure occurred.
  • Engine RPM - A live reading of engine RPM to aid the user in accessing the Similar Conditions Window.
  • Adaptive Memory Factor - The PCM utilizes both Short Term Compensation and Long Term Adaptive to calculate the Adaptive Memory Factor for total fuel correction.
  • 200 Rev Counter - Counts 0-100 720 degree cycles.
  • SCW Cat 200 Rev Counter - Counts when in similar conditions.
  • SCW FTP 1000 Rev Counter - Counts 0-4 when in similar conditions.
  • Misfire Good Trip Counter - Counts up to three to turn OFF the MIL.
