How much would it be to just get a mechanic to look at it or is it just that my engine oil was cold that this happened the temp Gauge was way over in the cold side
likely an O2 sensor, or could just be the need to running till it gets warm drive it on th highway for awhile and it might clear. that warning light IS NOT critical. you can get it scanned and find out exactly what tripped it later, but it's not something you need to worry about immediately.
your van would brake and you would lose most if not all controll it would look something like final destination or you could just break down and be SOL **** OUTA LUCK
If the check engine light comes on that means that you DO have a problem with your electronic control system! I would take it to an auto parts store and have the codes read (don't listen to what they say it is)just get the code numbers and come back home and post them on your question and we can help you! ADDED: And don't forget to provide us with the vehicle information YMM (year, make, model and engine size if possible)
