For the past few weeks, my temperature gauge will occasionally read hot. The "check gauge" idiot light comes on, and it's all the way up in the HOT zone. I think I usually let off the gas as I look at the gauge. It stays on HOT a second or two, and then falls back to normal.

Ideas?

EDIT: Oh, it's a 2002 with 140,000 miles

 

Bad sensor maybe? Have you checked your coolant levels?

 

this or you have an air pocket in the system

 

DOH! Low on coolant!!!!

I'll take care of that and hopefully that solved my problems!

Thanks guys!

 

keep an eye on that. You might either have a leak or could be burning it.
