Does hot weather trigger the check engine light?

I've read on the internet that hot weather can make your check engine light turn on. Does scorching weather actually make the dreaded dashboard light turn on?

Answer
“Yes, hot weather can trigger the check engine light, but it could mean that absolutely nothing is wrong with your vehicle. However, some situations mean that this is just the tip of the iceberg in terms of problems.
If the check engine light keeps coming on, take your car in for service, or at least run an onboard diagnostic to make sure that nothing more significant is wrong with your vehicle. If there’s a bigger problem, you can at least get a diagnosis, find the problem, and pay for it out of pocket or with a warranty.
If your car ever overheats so much that it dies, make sure you have roadside assistance added to your car insurance policy. For industry-leading coverage at a fraction of the cost, try using Jerry’s partner, Urgently. Urgently pays for an Uber if you ever need a tow (and don’t worry–the Uber will have air conditioning to cool you off on a hot day). For only $50 a year, Urgently can offer you reassurance that you’ll never be stranded due to an overheated car!”
