2005 avolon toyota display temp light is out

This is known as 'dieseling'. The most common causes are

-idle speed set too high

-engine operating too hot (faulty thermostat, faulty temp sender, leaky head gasket)

engine timing is out (loose distributor clamp, worn timing belt, faulty timing belt tensioner)

-

If vehicle is equipped with ambient temp display and there is no display, check sensor for disconnected/broken. It should be located in front of the radiator area attached to the upper radiator support or one of the brackets bolted to this support

Bad shifter or cable, or attaching hardware.

Are your cruise control, dome, and tail lights also out? If so then it is a fuse. If not then the control unit has gone bad internally. You may be able to get it fixed under your warranty.

its on the left side of the engine below the exhaust manifold, best got at from underneath the car

Take it buy Auto Zone when the light is on and get them to check the code for you. I don't know why it would do it while cold and not hot.

check if you got a burnt out light and then trace that wire back using your manual.
