2.2 and 2.5 Computer Codes

Getting the Codes

If you have fuel injection, this works on most Chrysler, Plymouth, and Dodge cars made in the 1980s and 1990s.

• Start with the ignition off. Within five seconds, switch the key on, off, on, off, on. (On is *not* start!)
• The "check engine" light will flash. Count the flashes Each code is a two digit code, so a (for example) 23 would be FLASH FLASH (pause) FLASH FLASH FLASH (loong pause)
• It will never flash more than 9 times, watch for pauses!
• 55 is end of codes, 33 is normal on earlier models if you don't have air conditioning.
• Please note that some codes are NOT included below, this is not a complete listing, but it IS very close to complete.

On newer cars (mid-to-late 1990s, 2000s):

• On later models with a digital odometer, the codes may be displayed on the odometer rather than blinking the check engine light.
  On 1995 and later Neons, and probably other Chrysler, Plymouth, Dodge, and Jeep models, when the check engine light goes on, you may be able to get the codes simply by putting in the key and moving it to the RUN position; the light will blink out the codes without all that OFF-ON stuff. This will not work if the check engine light is not already on.
  Simultaneously press the trip reset and trip/odometer switches; while holding them, turn the ignition to RUN (not start), and wait about five seconds. This sends the car through a short self-test sequence that ights all segments of the odometer and shift selector read-out (where applicable). It will then display the stored error codes.
