My check engine light is on and when tested it said that it was coming from the temperature sensor. I bought the temperature sensor, however I don't know where it is located exactly. My car also at random times runs high RPM's and jerks. Could this be caused by the bad sensor?
Do you

I would first ask is the manufacturers warranty still in effect? The answer to your question is yes it certainly could cause the issues you describe. The temp sender is located close to or at the thermostat housing. I am temporarily unable to access Mitchell on demand and will repost if needed at a later date. I apologize for the hassle.

That does help, but if you could post later to the location of it, I would greatly appriciate it. It does calm me to know that the bad sensor would cause the problem. Thank you so much.

Is the warranty question out of line or does it not apply?

We bought the car used about 3 years ago as is so we don't have a warranty with it, unfortunately. It's been a good car so far, until now with this sensor and the fact that our speedometer quit on us, however I think that is just the speed sensor and I need to order that.

Ok, so I found the temperature sensor and got it replaced and now my check engine light is off. My car started with no problem, fan doesn't kick in all the time, no jerking, no high rpms; she's purrin like a kitten. This is for everyone else if you need to know where the temperature sensor is on a Hyundai Santa Fe:

When looking at the engine from the front of the car, look to the right side of the motor. You'll see the radiator hoses (top one, then bottom hose right next to each other). Put your hand on the lower radiator hose and run it underneath and toward the motor (still underneath the hose). Now between your hand will be the lower hose (above your hand) and two other lines (below your hand). As you move toward the motor you'll find a plug. That's it. You can't see it from above, but it's there. Use a 16mm deep socket with about a 3" extention to get it out (after unplugging it). Be careful, because water/antifreeze does come out and if you just were running your car it will be extremely hot. After replacing the sensor don't forget to fill back up with water (only about 1/2 gallon or so comes out). Well that's how to replace a Temperature sensor on a 2001 Hyundai Santa Fe.
