Most Common Reasons Your Check Engine Light Is On

In this video you can see what are the most common reasons why the check engine lights up on or starts flashing.

On our website you can find a more detailed tutorial on the check engine light topic:

As you'll see, making an inspection on your own may at least narrow down or even solve the check engine light problem.

Excellent presentation. Spoken clearly without shouting!

Thanks a lot, removed my air filter cover on my Toyota Land cruiser, to check the rubber seal, and found my diesel sensor disconnected. Pushed it back in, closed the filter cover, and it solved 2 problems in one go: the engine light turned off, and my diesel gouge stopped giving false reading of low fuel.
Again, many thanks, Big Like from Israel.

Excellent advice, just saved me £114 diagnostic test at Honda garage by cleaning around rubber seal on fuel cap🥳

Light on today. Straight to youtube ! Thank you. Best video here on this issue

[cheryltune]

You explain everything very well and correctly!

Thank you so much - sensor light was all due to the fuel cap. In the past I have been quoted thousands to fix this same issue.

I have a 2005 Ford 500 Limited that's been meticulously maintained. My "Check Engine" light recently came on and the problem was the gas cap. Be advised the light WILL NOT go off immediately. It will take a couple of cold starts to reset. Thanks man!!

Solved the issue in check 1. Probably saved me a few hundred "analysis" from a tech, so thank you!

Is the Toyota Yaris 2011 Terra Sporty engine belted or chained?

Thank you so much for this. I was on my way to collect my Grandchildren from school, tried the petrol cap tip & the light went off! Thanks again, saved me the trouble & money of going to the mechanic. Sincerely & so grateful Joan

Thank you for this video. What I don't like about a franchise shop like the one I went to diagnose my issue, they always recommend to change to new parts vs cleaning it first. That would not be a good place to go so now I realize those small independent shops would do a better job. Never have them replace the part until they've look at everything and do the cleaning up under the hood. I have an engine check light again after 2 years now. The first time my O2 sensor was changed but it did not help, the shop had no idea. Finally we checked out the air intake and that was cleaned. It did the trick as I looked up the obd2 code online to find other areas of concern.

Thank you sir for summarizing those usual CEL problems. I think those are true for most make and model of vehicles.

Thanks for this informative video. In my car the coolant warning symbol came on, I let it rest and drove to my nearest destination and the check engine light came on. Took it the garage and they poured water in the radiator and but the light is still on. What would be the next best course of action?

So my new Hyundai i20 started showing that light on, garage schedules but engine power is clearly limited... and it sounds like a paper on the wind sometimes, weird stuff... wonder if you could give some light on a possible issue.

Thank you. My EML was on because of loose petrol cap. I tightened it and EML went out. Thanks pal great video

They can send a man to the moon, but they can't make a sensor that tells you what problem your car has?
SAD! 😢

Once I have changed the Gearbox, this engine check light getting ON in red color. It is only appears when I travel to 5 or 6km continuously. If I stop the engine and start again, the indicator getting OFF.
What may be the issue? Please advice me

This is a great video! Ive gone through all these except change 2 of my 02 sensors and clean the catal converter after taking my 2007 wm statesman to a mechanic without a resolution. The odbc gives off the p01010 (code that refers to the maf sensor..) unfortunately replacing with a new bosch one still didn't resolve it.. I may have that odbc code wrong above but it was for the maf... if the mechanic who is over 30 years qualified can't resolve im not sure what else I can try :(
