Check engine lights come on for many reasons, but the tire pressure would not be related unless your computer is malfunctioning which is doubtful. The CEL is for engine related problems, not tires.

There is a tool called an OBDII. OBD stands for On Board Diagnostics. The II stands for 2. This is a standard for all vehicles newer than 1996 and the code it presents you with has a corresponding explanation to help mechanics repair the problem.

I had a code P0420, which translates to a catalytic converter problem, but in fact it was a malfunctioning Oxygen Sensor indicating the catalytic converter wasn't working properly.

Some places will scan your vehicle for free to give you the code, others charge. I bought the tool as it also allows you to reset the light (turn it off) after the problem is fixed or turn it off and see if it comes back on again (sometimes a simple thing like a loose gas cap will cause the CEL to come on).

2004 4 runner: Low tire pressure warning light is on, even though there is no tire pressure issue. Is this a sensor problem? or maybe the light is not working?


the senors tell you if the tire is low or even if the tire is not low if the tires are off a couple pounds from each other then the light will come on.

The words tire reset keep on popping up on my dashboard. What does that mean, and how do I get rid of it? 2004 Ford Freestar.


With and without "Mesage Center" respectively (pretty sure)

With the engine on...

Push "Setup" button, until your driver display says something like "Press Reset for system check".

Then push Reset. The system check will start, rotating through a series of checks.

About the fifth or sixth check will be the tire pressure. The system will sound the tone (same one that starts w/the light) and It'll say something like "Check Tires Pressure" on that moment press and hold for 3 or 4 seconds Reset. When you release the Reset button It'll show "Hold Reset if tires are OK". While that's up, hold the Reset button. After 3 or 4 seconds, the tire warning light will blink 2 or 3 times and then will stop .You need to be ready for it, because you don't get very long to release.

How to reset the low tire pressure warning if the vehicle does not have the "Message Center"

Turn the ignition to the ON position,
depress and Trip/odometer button (located in the instrument cluster) until "TIRE RESET" or "CHECK TIRE AND RESET" is displayed in the odometer display window.
Once "TIRE RESET" or "CHECK TIRE AND RESET" is displayed, press and hold the button for three seconds.
The low tire warning indicator light will flash three times as the low tire warning system begins to initialize.

This information is in the Owners Manual

Hope it helps

2000 Sienna exclamation light on dash


That usually means that one or more of your tires has dropped below the level of air pressure that the manufacturer recommends. It is basically a low pressure warning light. This way you will know to find a place to check your tire pressures. Look on your tires sidewall and you will find a cold psi rating and a hot or warm psi rating. The tire pressures need to stay within those parameters in order for the light to not come on. As the tire warms from motion the air inside begins to expand and will read a higher pressure than if the tire is cold. Check your pressures and if any of the tires have a low pressure (below 30 psi) it should be inspected...........Or you may be leaving your emergency brake on. Pull up then push down to release a hand break lever and push all the way down and pull hard on the release lever for a foot brake. Another possibility is the car needs brake pads soon.

Same light...


That light on the toyota sienna is drumroll please,,,,,,,,,, the air in one or more of your tires is low!! It would have made more sense to have a picture of a tire or the word tire or whatever,,, not sure what that symbol actually is, but check the air in all your tires and One will most likely be much lower than the rest. The tire pressure on the sienna I believe is 35 psi all 4 tires, but you can double check by looking on your doors.

A yelloow light inside dashporrt light up ( ! )and is something like this and i don't know what is it.


The light that you speak of is the Low Tire Pressure warning light. This light comes on if your tire pressures are not at the right pressure. Inflate the tires, and the light should go out.

The light that came on, on my dash is just on the left side of the spedometer looks like a horseshoe with a little line across the horseshoe and its orange in colour.


Hi there... the light that you are mentioning sounds like the tire pressure warning light. If one of your tires is low on air pressure, then the light will come on. also depending on the temperature outside, the light may come on too.if it is below 0C the light tends to come on because as weather gets colder the tire pressure gets lower. Hope this helps you out.

2004 Toyota Sienna - round yellow light with two dots inside?


That symbol is the low tire pressure light. You have a tire that is right at the minimum threshold. The light goes off as the tire temperature rises, and, as the temp rises, the internal air pressure also rises slightly. Just check the tires with a good pressure gauge, inflate them to the specs printed on the tag inside your driver's side door, and you will be just fine.

Dashboard warning lights.


The warning light that looks like a pot or kettle with arrows is the "Low tire pressure warning light*" I found the answer on the Toyota web site by registering, logging in, entering my model and searching the owners manuals for warning lights.
