I bought a 2010 Caravan about Nov of last year, and the check engine light is on. A few weeks ago the outside temperature gauge was off, it was displaying -35 in Alabama in the summer. I am going to take it in under warranty, but has anyone experienced this, temp not working properly, then the check engine light comes on? I guess the question is could these 2 things be related and could this be a bigger problem? The van has 8K on it and it has the 3.8. Thanks Jack

There is a Chrysler TSB #08-011-10 (Google it) to address inaccurate or slow updates of the EVIC outside temp display. It involves a software flash of the CCN (instrument cluster) module.
The 'ck eng' light may not be related to this unless there is a bus communication, etc. issue. We would need a stored 'P' code to tell us where the problem is for further diagnosis.
This fault code would be stored in the PCM (powertrain control module) and should be able to be read with any OBD II code reader. Don't erase the code as the dealer will need it to be present for the service.
