Can cold weather cause my check engine light to go on?
As the car battery works harder in cold weather, the engine will be slow to start or won’t start at all. The check engine light will come on to indicate that there’s a problem. When it’s cold, the pressure in the vehicle tires will decrease. The engine light will light up due to this as well.

antifreeze and coolant will solidify at -32 degrees Fahrenheit — (-18 degrees Celsius). This means the engine can stall and be harder to start.
How do you warm up a frozen engine?
If parked outside in cold conditions, a frozen engine can take days to thaw properly, unless it can be safely moved to a garage or other sheltered location. To speed up the thawing process, it is possible to use a fan heater placed in front of the radiator.
