92 dodge dynasty got flash codes 12,21,55 what are they

Code 12 is a "battery disconnect" code. It simply means that the computer has lost battery power within the last 255 engine starts. If you have recently disconnected the battery or have had to jump-start your car, this is the reason for the code and there is nothing to fix. It will clear all by itself in the next 255 engine starts or less.

Code 21 is an oxygen sensor code. It can mean that the oxygen sensor is rich, lean, or simply not switching properly. If the oxygen sensor is very old, it is probably the oxygen sensor itself causing the code. However, it could also be due to the engine actually running lean (not enough fuel) or rich (too much fuel) for a large number of possible reasons.

Code 55 simply means that the computer is working properly and has finished outputing all of the stored fault codes. The only time to worry about a code 55 is when you do not get one. If the computer does not give you a flash code 55, this is an indication that the PCM is faulty. On an engine that is running properly and has no problems, code 55 will be the only code displayed - just to let you know everything is working and you did the key "ON-OFF-ON-OFF-ON" thing correctly.

First of all, take it to a place like Autozone auto parts or call other parts stores to see if they can hook up their hand held analyzer to your car's computer, This is a free service that is very enlightening. You will get a printout with the codes and what they mean. take care and good luck

Jag X-Type 2.0 V6 Auto (2002). Amber engine icon lit and aircon switches itself on. No loss of power/drives great. Temperature gauge appears all normal. After a while aircon switches itself off again -...

The Amber Engine Icon means the same as a Check Engine Light. Your car's ECM (Computer) has stored a Trouble Code, and you will need a OBD II Reader (On- Board Diagnostic) to get the code so you can diagnose what is wrong with your vehicle. You can go to any AutoZone and they can read the code for you at no charge. You will need to diagnose and fix the problem before the Check Engine Light will turn off.
