SOURCE: Check Engine light went on cold weather on Mit Galant 2002

There could be a number of reasons why the Check Engine light is on. US vehicles manufactured prior to 1996 feature a diagnostic module in the engine compartment by the main fuse box. Often a label is affixed to the underside of the hood explaining which terminals to access.

Using a simple metal tool (even a paper clip) to connect the two terminals will cause the check engine light to flash in the dash when the key is in the accessory position. By reading the number of flashes one can determine which code was set. Manufacturer’s code guides, available online, will reveal which system(s) tripped the check engine light.

It could be a vacuum leak, dirty fuel injectors, blown head gasket, etc. The longer you drive with the Check Engine light on the more damage you are doing to the vehicle. So if you are a DIY type of a person then you can check the code on the ECU or bring it to a dealer near you.

SOURCE: 2005 chevy colorade check engine light comes on in

Has this problem come shortly after refuelling? Do you live in a humid climate? 9 times out of 10 this is a result of the gas cap. Failing that, can you get your hands on a OBD 2 tool or go to your dealer and have them scan the truck. The Check Engine Light throws a code and the OBD2 tool reads that code. The code points to the problem.

Need to know about how to solve the engine check light that turn on.


4 most common causes of engine light on
-oxygen (O2) sensor
-loose fuel cap
-very cold weather affecting airflow under the hood.
-in need of oil change.
check these. As for fuel cap, make sure you crank it around a few times after each fill...very cold weather, you just have to wait. Save your engine with an oil change regularly, and get your mechanic to show you where the O2 sensor is on your vehicle. May just need the contacts cleaned.

Will not start in cold weather


Check your battery for voltage! You need minimum of 650 Cold crank amps to start the vehicle in cold weather. If your battery is at 12Volt range start the engine and check again for alternator recharging it It should be at 13.5 Volts range!

Hi Danny, I would have both the vehicle and the remote fob batteries checked and if required, replaced. Cold weather can and does show up problems with batteries. It would also be a good idea to have a diagnostic scan carried out on your vehicle, just to be on the safe side. Regards John

Engine light not showing in cold weather


It could be the ecu, but before you purchase a new one, have a shop check the power feeds and grounds for the ecu. Sounds like it could be an electrical connection that only has good contact when it's warm.

I started my car this morning and it was idling rough. Then the check engine light came on and while I was starting to drive to work it was shifting quick and hard into and out of gears. Eventually it...


yes some times when initial cold start a sensor could get a mis read due to alot of variables,and it would cause trans to shift abrupt. the good thing is it did correct itself and the computer reconized this and detects no stored code. recommend to let vehicle warm 5-10 min before drive. In cold weather you should never just jump in and start car and take off. should always let engine and fluids get to operating temps before drive, This will prolong the life of the motor and trans from internal (expensive) repairs.

BMW 325xi; 160k; check engine light on-->next day, wont start!


I would try to jump it to see if the starter engages and the engine runs, if it does you have a connection problem between the engine starter and the battery, if it does the same thing with cables then you will probably have to tow it in to the shop. I do not think your problem is related to cold weather, but it could very well be related to the check engine light. Exactly what the check engine light is on for I can not say with out a code, but I agree with your thinking about taking it to the shop. Hope this helps, let me know.

Gasoline type


I use 87 octane with Lucas Oil fuel additive. Car runs noticeably better, gets better mileage and solved problem with engine fouling in cold weather (which caused check engine light to trip). Audi dealer service rep told me that premium cold weather fouling has been traced to additives commonly used in premium fuel. That service rep "unofficially" recommends using 87 octane to customers experiencing problems with engine fouling in cold weather starts.
