Temperature reading..outside

So it seems that my jeep doesnt register the correct temp if it goes anywhere over 90. Its been stuck on 77 yesterday and today. And its in the upper 90's. Same thing happened last time it was hot out. I have a 2009. Anyone else had this problem??

Dirt, oil or corrosion in the connector would short or change resistance, changing the value the computer reads from the sensor. Temp sensors are typically somewhere behind the grill and in front of the radiator. Cleaning the connector is the only thing I can think of, other than getting a new sensor. Often they are pretty cheap and can be found at the local auto store.

I've only had the natural, stuck in traffic, no airflow allows some engine compartment heat to warm the sensor to read hotter than actual temps, it always cools down to the correct temp once I get moving and the airflow removes heat from bleeding out of the engine compartment. Reading colder than the known temp sounds likes its definitely a malfunction of some sort.

Mine has stuck at a lower temp for a few days. I have an '07 but I think I remember reading somewhere that the location of the sensor is a problem if it reads hot but a reflash of the computer helps the low readings.

I can't remeber if this has a TSB but I'm sure someone else will chime in.

The lower readings on mine seem to sort themselves out after a day or two.

This is the TSB to move the sensor farther away from the radiator, for incorrect readings.

Mine was not correct since new. I complained several times under warranty. They replaced the sensor after the third trip. I explained the software update was supposed to correct the problem. They did not think so.

I recently paid for the software update which corrected the problem. The outside temp is now accurate and changes on the fly, as it should be.

If it was me, I would write Chrysler Customer Service or your Local Zone Office, let them know the Dealership's name, that refused to do the software update nor did they fix the problem under warranty, until you paid for the update after the warranty was up.

IMO, software updates should be free, at the very least Chrysler should set a fair policy and make sure the Dealerships stick to it.

I've been told the policy was, if the vehicle is in for service already, and there were software updates, they were to be performed at no extra charge.

If its under warranty, and there is a software update that address's a problem a customer is having, obviously the software update should be done free of charge as part of the warranty.

I could see, if customers want software updated even though they don't have a problem, that they would charge for them, although IMO they should provide them for free.

Its another thing if you have a problem and there is a software update to fix it, says to me there is a defect in the software and should be performed for free, NOT make the customer pay to fix Chrysler's software defects.

I thought about complaining but have read others run arounds complaining at them before. Sounds like stress to me. I called dealers until I found one that would update it cheap. The prices vary big time. Small towns seem the way to go.

Did you by chance get this problem fixed? Mine started doing the same thing this morning. Three days solid of 100+ then today it's stuck on 77 when my phone shows it to be 98.
