Chrysler Repair Questions? Ask a Mechanic for Answers ASAP
Do you mean the O2 sensor monitor and catalyst monitors are not showing as being ready during emission testing?
Is the check engine light on?
Ok, what the mechanic is referring to is system monitors for the O2 sensor and catalytic converter. They are not reading as ready. This happens automatically if the check engine light is on. It doesnt always mean that either the O2 sensor or converter are bad. It just means that the systems wont complete their cycle to set as ready due to the check engine light being on.
We need to know why the check engine light is on at this point. There are over 500 causes of the check engine light being tripped by the computer. So the computer needs to be scanned for fault codes which will tell us the area of concern.
Do you know if your daughter had that done yet, and if so, what are the fault codes? They will be Pxxxx codes - example - P0420
