We are going through some extreme cold temperatures like 3 and 5 degrees with wind chill of minus 13 the last few days and for Oklahoma this is extremely unusual. We could not get my van into the garage because of the blizzard we were having. It set out 36 hours with out being started. When we were able to get out of our driveway the check engine light came on and has stayed on. It is running fine otherwise.
Can extreme cold temperatures cause the check engine light to come on? on 2005 Chrysler Town & Country
Yes, it is possible. My guess would be the O2 Sensor heaters are not heating fast enough or are inoperative. Also something to consider is that with freezing temperatures and ice formation, the sensitive electronic circuits may be receiving false voltage readings. Have your local repair shop or dealership perform a diagnostic scan test to read the codes and whether they are stored or active. A stored code may go away over a period of driving as long as the condition that set the code is not present any longer.
