[estias]

Did you try checking the fuel tank level sensor? It might be under the rear seat. Pull it out carefully and check. Try not to smoke while you are doing iot and try not to drop anything in the tank also.

Did you run out of fuel while on the road?

machan in that case the fuel gauge will also fail innit ? the OP doesn't mention anything that sort

[VVTi]

True, but the fuel gauge sender has a contact to throw the light when the floater reaches a certain level. That could be stuck or many other reasons. Checking is the first thing to do.

I have the same problem in my carina. I will check the level sensor as VVTI said.

Members,

Remove the tank unit and check up the end connections are OK, If you earth the bulb wire then the fuel low bulb will work.

At the same time check the tank unit end out let connection, when the level is very low the fuel meter light will come on.

By connecting a bulb on to tank floater unit on your hand, have to move the floater unit up and down by hand. to check the bulb signal connection.

Guys what's the attached warning light indicates? Is that the low tyre pressure warning? It's a Corolla 121.
It appears one or two times and went back.

Too blurry, but that looks like the "Tyre pressure warning" indicator.

It is the low pressure warning. Make sure you have equal pressure on both tyres on front and back. Hope the tires are identical. In a very rare case it could be the wheel sensors needing a simple clean up.

Thanks guys. Most of the tyre pressure warning lights on internet had virticle bar instead of horizental one as in pic.

Is it a single sensor? or all 4 wheels has 4 sensors? I am not using the car, its with a friend. He has pumped Nitrigon .. Could inflating one wheel with regular air can cause this kind of problem?

[Rumesh88]

The ECU of your car gives out this alarm when there is a difference in the wheel rotational speed consistently over a predetermined period. An under inflated tire has slightly smaller diameter and hence a lower tangential speed compared to correctly inflated wheel. I do not know if mixing up nitrogen inflated tires with those inflated with regular air to the "same pressure" can result in differences in diameter but if it does for some reason then you may get this alarm. There are four sensor for the four wheels and the same sensors detect wheel lock up to enter the braking system into ABS mode.
