Noise when going forward+ high temp sensor

I have two issues I’m hoping to get input on. The more worrisome one is something after being parked. I can be parked five minutes or hours. When I drive forward it feels like it’s struggling, my first instinct is I’m running over something from the resistance. It doesn’t continue and so far does not happen backing up.

The second is the temp gauge shows the outside temperature as over a 1000 when it’s hot. My first thought is sensor issue but it had additional issues on a recent trip. The engine had a roaring noise that only stopped after putting more coolant in.
Any leads would be appreciated. I’m taking it in next week but they seem to have trouble recreating the issues.

I am of Scottish decent and I ride a Unicorn.

total guess work... Maybe the parking brake is not releasing like it should? even if the solenoid is activated to release??? Meaning maybe a pad is sticking even after pressure is removed?

On the second, If you are having to add coolant you have significantly bigger problems than a temp sensor. Did you add the coolant directly to the radiator or to the over fill tank? How much did you have to add?

Yeah, Mr Unicorn's an excellent guesser! But, you need to schedule service with your dealership soon - They'll get ya fixed..

I have often found that after guessing at things... I am often wrong. Your dealership recommendation is the best advice.

Thanks for the reply. I don’t use the parking brake. In a separate thread a Lot of folks mentioned the park/hold but I also don’t use it. I wonder if it’s something similar, though.

They looked for leaks on the coolant but didn’t find any. It was consistently hot when I had the main issue. The super high temp showed up again after less than an hour in 90 degree sun. I checked the coolant and so far its level is good.

I think that there was someone else a ways back, that had the temperature issue. I think there was some sensor issue. It has been quite a while since it was posted. Maybe there is something related that is causing a limp mode?

Well that does not rule brakes out but it does make it sound like they are not the culprit. Beyond that... You are into bearings and gears. You need a mechanic to get it in the air and start tracing things back one bearing, one gear at a time.... It may be at one wheel or more, front or rear.... sorry just think out loud.... Get it up in the air and start turning things...

The temp??? ohhh. I would hope Tim is right and it is a sensor and not something physical. getting it on a computer would make diagnosis a lot easier.

I would also look at TSB’s issued for your year Sport to see if there are any related to your issues.

To clarify when you are talking about temperature sensor are you talking about coolant temperature or air temperature sensors. If it is the air temp sensor that is a $5.00 part and a ten minute fix the sensor is located in the divers mirror IIRC.
The parking issue might be from not using your parking brake- you really should use it every time you exit the vehicle. But if there is even a slight slope you are resting all the weight of the vehicle on the parking pawl. That is a lot to ask a 1/8” pin to hold. Is it hard to shift into drive? Is it every time you park or just in a certain parking spot?

Quote...The second is the temp gauge shows the outside temperature as over a 1000 when it’s hot...End Quote. If you read the quote words, well....what can I say...well...never mind.

My 1st guess is GLOBAL WARMING!!

On a serious note. I had overheating issues on my 2017 F-150, I know it's not a Bronco, had the dealer ran all the coolant in, coolant out tests, they were all good. No blockages, radiator test was good. It turned out to be the coolant was failing, I think it got a D-. There was a tech order telling them to switch to a different type. That solved the problem. Might not be the case for the Bronco, but something to keep in your hip pocket.

Good morning. Are you still experiencing these concerns with your Bronco? If so, I would like to look into them on my end. Please send over a private message with your VIN and the name/location of your local Ford dealer.

On the 1000 degree reading. Just got back from a road trip out west with our 23 Big Bend sport. Several places we were at the temperature was triple digits. So at one stop the outside temp was 100. I got in the car and then my grandson got in, started it up and I saw a 2100 deg reading. Holy s**t it's hot, but Hell? Then my wife gets in and the reading goes to 3100 deg. Now she is hot but not that hot! Then after a few seconds the reading is back at 100. Then I realized that the seat belt image was in front of the 2 and 3 as the vehicle lets you now how many people are belted in. So with a triple digit outside temp there is no separation between the belted passenger count and the temperate hence the appearance you have gone to hell! Now if there were 4 passengers (4100 deg). Great engineering.
