Check Engine and Temp. Light?

I started my car, the engine light came on, about 2 minutes later the temp light came on and the gauge was past hot. I pulled over, popped the hood, checked coolant and oil, both were normal and engine was cool. but the fan was on.

when i turned the car back on to drive the rest of the way home, the temp guage would change with my speed (high to low and back rapidly), but the lights were still on

I bumped a higher then usual curb when i parked it, could this have caused the light to go on?



And how do i get it fixed without spending an arm and a leg. or is that not possible?Check Engine and Temp. Light?
You'll want to pull the codes and find out what threw the check engine light. Autozone will do this for free.



If the temperature was really way up past hot, the coolant should've been boiling. Since it's acting erratically, my guess is that hitting that bump might've dislodged the temperature gauge wire from the sending unit.Check Engine and Temp. Light?
not likely , the temp prob changed with speed because the faster you went the more air was flowing into radiator first what kind of car do you have you might start with thermostat waterpump,coolant temp sensor or might have a dirty radiator if u have a check engine light on it might be because the computer read a high temp
