I have an issue I have had the truck a little over a year and every few months I had P0124 pop up, I have just replaced the sensor each time but recently I have had the code come up more frequently and can't figure out the ultimate fix. Everything else works fine, I have no issues other than the code popping up, My gas mileage has stayed the same this entire time, any help is appreciated!

 

Could be caused by a dirty/sticky throttle body.

I'd give it a good cleaning with some throttle body cleaner.

 

I will try that in the next few days, Thanks!
