I have a 1995 RAM 1500. The check engine light is on. I checked the codes and get 12-32-55. Where do I find what these codes mean?
Don't worry about 12 or 55. 12 means the battery has been unhooked in the last 50 to 100 engine starts. 55 means end of session. I get 32 on mine from time to time and it has to do with the EGR or purge system.
