In the front of a friend's car this yellow light is lit on a Rav4.

How do I find out exactly what it might mean?
Do I need any special tools?

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

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.

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.

Or more likely just pumping up the tire. The tires that came with my
Corolla were really good except for ONE which lost enough air in a month
to trigger the light. Pump the tire, be happy for another month...

I finally replaced the tires (one blowout, others too old [10 years] for
any shop to touch them) with the same ones. Took 6 months to lose
enough air to trigger the light. 20-24 lbs instead of 32.

The $35 pump from Harbor Freight is handy. Don't get the cheap one, it
burns out after 2 or 3 tires in a row. A digital pressure gauge is also
a nice thing.

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.

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!

I want to go back to my little grass shack in 1965.

You can get valve caps that indicate when the tire pressure is low.
That's a little less convenient than TPMS but a lot less expensive.

My 2004 Sienna is, I think, one of the last years that they did the tire
rotation thing. Then they switched to the in tire battery powered
sensors, which I think are now required.

A few years ago I got a scanner adapter to connect my car to my computer
and a maybe illicit copy of the Toyota techstream software for 30-50
dollars.

I just looked up techstream and found this"

Illicit minds think alike. IIRC I had to buy two copies (though
neither was as much as 30) but I got it to work. (With XP. Fortunatly
I still had my XP laptop. wouldn't work with whatever I had that was
newer.) But it wouldn't change what I wanted. All I wanted was the
fob to open both front doors with only one press, not two. That option
didn't exist for my 2005. And I wanted one other little thing I
couldn't have too.

I'm glad I didn't pay the dealer to tell me it couldnt' be done.



Cindy will think I'm a fool for caring if it takes one or two presses to
unlock the passenger door.

If the light blinks for 1 minute after you start the car, you have a problem with the tire pressure monitor system. If you have a steady light you should check the tire pressure. I've had that problem for years. The sensors have to be replaced because all 4 batteries in the sensors have run out of juice. Unfortunately, to replace the sensors, you have to dismount the tires from the rim.
On a 2011 RAV4, I can't see ever replacing the sensors. That light is pretty annoying. I find that meditation helps. It looks like your friend has a Hybrid, that's cool.
