You'll need to have an auto mechanic who specializes in smog check repairs
diagnose your Chrysler. Truth is even thought the check engine light is not
on now, check engine light trouble codes have been stored in your vehicle's
engine control computer. Those trouble codes can be extracted using a
trouble code scanner, and then used to diagnose the specific emissions
system they pertain to. The average mechanic who does not understand auto
emissions systems does not know this. Code that trigger the check engine
light on intermittently are called soft codes, as opposed to hard codes
which trigger the check engine light on constantly.
