What does this yellow light mean on the front

It's a tire pressure warning. Don't forget to check the spare as well.

A tire pressure warning as Cindy said. You can find plenty of tire pressure testers in the automotive section of places like Walmart or go to an auto parts store. An your auto parts store might be a better choice. One of the employees could give you a short course on using one. YouTube?? Many gasoline shops have an outside air hose you can use to fill a low tire. A tire that keeps losing pressure needs to go to a repair shop. It might have a nail in it. Don't overfill the tire. There is a note on the side of the tire about pressure. Your owner's manual should have it also.

The pressure listed on the tyre is the _maximum_ it's considered safe to reach.

Generally the manufacturer's recommended number is quite a bit lower and will be on a sticker by the driver's door frame.

Higher pressures will improve gas mileage, lead to a bit of a "harsher" ride, and might/might not change handling..

Could you check the tire pressure first?

I have a Toyota that the tire pressure warning light has been on for over 5 years. I just check the tires every so often like I did for about 40 years before the warning light. I am not going to pay about $ 75 per tire as the battery in each of tire monitors fail. The truck will pass the stupid state inspection with that warning light on.

Same here. When I take it in for service, they reset it. A short while later, it's on again.

I also have the "check engine" light on. The Wisdom of the Internet thinks it's benign, that I've simply had a little backfire.

We don't have a state inspection, so hooray.

I just posted exactly what the web site said which was those three lines. It says seeing that light requires calling or visiting the dealer. Do you think maybe they know something we don't know. Why else would they say what they said? Presumably it's in the owners manual said that way.

LOL!

Many manuals will say see the dealer for many things. Could be just a 'cover your ass' thing for the dealer in case someone messes up a repair and sues them. This suppose to be a group for people that want to repair their own stuff.

If it's a one-time event the light will go out after a number of driving cycles . Have you had the codes read ? Simple procedure , and most auto parts stores will do it for free . Some codes are indeed benign . Others can result in excessive fuel consumption and catalytic converter damage . And some will leave you standing next to your car waiting for the tow truck .

I had a car that the check engine light came on at I think 10,000 miles. It was just a light that connected to the milage and was thought by the maker that an exhaust sensor would be bad at that milage. They found out that was not the case and the dealer sulution was to cut the wire going to the light. Not sure of the car but think it was a Chevett of the late 1970's or early 80's.

My impression is, and I could be wrong, that on cheaper cars the light goes on mostly for reasons about air pollution, bad 02 sensor etc.

And for fancy cars, the maker adds a bunch of other things that one really cares about, accessories, conveniences. But I've never had a car both new enougg and fancy enough to know first hand.

And the label in the door jamb.

I bought a car with the check engine light. I think that's why it was so cheap, 3000 or 4000, probably 4000, but I was afraid to discuss it with the seller.

It took me 3.5 years to fix it. But during that time I checked the mileage and it was up to spec.

It was lean mixture. I did all the tests and replaced the simple parts and was going to start replacing 1 or 2 02 sensors when I leaned on the big (4") hose from the air clearner to the ... I forget the name, and the hose came off. Nothing I could do would put it back on, becuase it had been on crooked for so long, but after I bought a new one, I could turn off the CEL.

There's a battery? I thought it used the tire rotation speeds and the sensors were powered by the electrical system.

My car is 18 years old. I've had it for 5, never replaced a battery, and the tire pressure thing works.

Sounds like a better system than wife's 2016 Toyota. I was quoted $350 to have all 4 sensors replaced. F' that.

Tire Pressure Monitor For Toyota

Here's a sample list of almost 50 codes :

FWIW, it's also a Toyota, 2005 Solara convertible. I don't remember if the manual is on this laptop or only the desktop at home but I hope to remember to see what it says about tire pressure monitors. But this thread will be 2 weeks into history by the time I'm home.

I missed that y ou had this link. I'll look at it.

FWIW, either because it's toyota, or because it's Japanese or Asian, or because it's years later, the shop manuals for Olds, Pontiac, Buick, and Chrysler that I owned were books that you could learn from, get to understand your car. The Toyota manual is full of tests using their own diagnostic and repair tools and I find very unhelpful except for the wiring diagram.

Maybe your video will be more help. It's 26 minutes, will have to wait until later!
