Service engine soon light came on soon after I had a fuel injector replaced. The last 2 months I have put 2000 dollars into my 1999 Dodge Caravan. I checked my gas cap and it did not resolve the problem....

You first need to tell us what the error code (s) is. The injector and gas cap are two completely different issues. Get it scanned and come back with that information.

A few days, but you need to have the check engine light checked. It can cause bigger damage depending on what is wrong.

How do I check my 1998 Dodge Caravan fault codes. My service engine soon light is on but I'd like to check it out before I take it in to the shop.

Take it to an auto parts store or rent a diagnostic tool to read the codes before taking it to dealer. Most auto parts stores will do it for free if equipped.

My 1998 Dodge Caravan has a service engine soon light on.

Well barwest , you should always have code 12 ,,, 1 blink then 2 blinks , this is not a prob it is a code to tell you that the onboard dyignostics is working. now for the code 55 this means that the code read is done . so the numbers in the middle is really your prob but you are missing a number with the 3 , do the key again and let me know remember your code is after the 1 blink and 2 blinks ,try that ,there is a number missing ok , joe
