Dodge Avenger 2.0/2.5L (1997 – 2000) Trouble Code Info

Model Year Engine identification System
Avenger 2.0L 1997-99 420A SBEC III/Mitsubishi MPI
Avenger 2.5L 1997-00 6G73 SBEC III/Mitsubishi MPI

General information

  • Refer to the front of this manual for general test conditions, terminology, detailed descriptions of wiring faults and a general trouble shooter for electrical and mechanical faults.
  • Malfunction indicator lamp (MIL) will illuminate or flash if certain faults are recorded.
  • ECM operates in backup mode if sensors fail, to enable vehicle to be driven to repair shop.
  • Trouble codes can be displayed by the MIL or by using a Scan Tool connected to the data link connector(s) (DLC).

Accessing

Flash codes

  • Within 5 seconds switch the ignition key ON-OFF-ON-OFF-ON .
  • Count MIL flashes. Note trouble codes.
  • Each trouble code consists of two groups [1] [A].
  • The first group of flashes indicate the ‘tens’ of the trouble code.
  • The second group of flashes indicate the ‘units’ of the trouble code.
  • A short pause separates ‘tens’ and ‘units’ [1] [B].
  • A long pause separates each trouble code [1] [C].
  • For example: Trouble code 21 displayed [1].

P codes, Hex codes & ORB codes

• Trouble codes can be displayed by using a Scan Tool connected to the data link connector(s) (DLC) [2]

Erasing

NOTE: Disconnecting battery ground lead may cause driveability problems until the engine management system relearns basic values.
  • Ensure ignition switched OFF.
  • Disconnect battery ground cable for at least 5 minutes.
  • Reconnect battery ground cable.
  • Repeat accessing procedure to ensure no trouble codes remain in ECM fault memory.
NOTE: Disconnecting battery ground lead may also erase memory from electronic units, such as radio.
  • Trouble codes can also be erased by using a Scan Tool connected to the data link connector(s) (DLC).
