Hi there!

P1299 Cylinder head over temperature protection active.

I would want to know why this is overheating. It could be a fuel issue, timing is too advanced (due to faulty sensors) or just a duff temperature sensor itself.

Needs investigation though as performance will be affected.

(If this assists in a solution, please rate as Fixya! Thanks.)

What's wrong with my temperature gauge?

Check the cooling fan is working and there is no blockage in the radiator/water system.

Trouble code p1299

Your PCM is going into fail-safe cooling mode. If temps really are normal then you may have a bad CHT (cylinder head temperature) sensor. Disconnect battery (negative wire) for one minute to get rid of code then road test your car to see how soon the P code comes back.

I have a 2000 chevy cavalier. The cluster started acting up. When I stop like at a red light the temperature gauge drops and the theft light, check gauges light, and service light comes on. When I give it...

I'd have to check your charging system, at idle. Any applicable trouble codes? At idle, I'd want to see the generator out-put over 13 volts, hopefully, much over.
You may want to check instrument cluster wiring connector for good voltage and ground?
Check belt for generator, correct tension? Just my opinion.

I have a light that comes on that is yellow and is above the temperature gauge. What does it mean and why do i lose power when it comes on?

This may be the service engine soon light which shows that you just went from closed loop to a limp mode open loop.

P1299... watr bottle keeps emptying..

The definition for that code is p1299 Cylinder head over temperature protection active. If your overflow tank (water bottle) is emptying check the oil for water contamination (it will look milky) also look at the exhaust for excessive white smoke, you may have a bad head gasket and hopefully not a cracked or warped head. Does the engine run alright? Has it overheated?
