2014 Hemi struggles to accelerate and loses speed

[Laidmuscle]

I was driving on the interstate going 65 mph and then the truck lost power my RPM shot up to 3,000 to 3,500 and went down to 40 mph.Check engine light and traction control light came on, I got it checked out at autozone was told it was camshaft sensor, talked to my uncle about what was going on, he told me a issue could be throttle body. So I replaced the throttle body and camshaft sensor, reprogrammed the computer for the throttle body. Went on a test drive got her up to 75 mph, all the lights came back on, lost power again but not like the first time on the interstate, she can get up to 75 slowly I can’t forcefully get her to 75, the screen on my cluster gauge says to service throttle sensor, if anyone has had the same problem or any ideas what I check I’d really appreciate cause I hit a wall and don’t know what to do.

OE sensor? Rams are notoriously picky about sensors.

 

[Laidmuscle]

Could be, every code it’s giving me is about the throttle sensor.

I think he means... did you install an OE sensor??

 

[Laidmuscle]

No I didn’t, where would I install a OE sensor?

Original equipment sensor.... IE... not aftermarket. These trucks do not like aftermarket parts at all.

If you didn't get it from a Mopar store and instead went to Advance, Oreilly, Autozone, etc... that may very well be the culprit. Buy a factory replacement and try again. May very well solve your problems.

Okay I’ll give that a try

You are just randomly throwing parts at it and hoping you get lucky. The engine code does not say "this exact sensor is bad and needs replaced". It can point you in the right direction to get started, but it doesn't tell you the exact fix that is needed. You also just randomly threw a throttle body on it. Some basic diagnostic is needed to determine what is wrong.

Sorry, I should have elaborated.
OE means Original Equipment.
In other words, a Mopar brand part.
