P0122 (Throttle position sensor voltage low)
Has anyone had this before? Is this something serious? I have always had P0441, problem with evap purge can, never had it replaced since it was not a big deal, hopefully this is not the beginning of chain reaction (I just had the radiator cracked twice in 9 months... it was replaced Nov 07).

On the side of your throttle body, towards the battery, there is two connectors the top on is the throttle position sensor (TPS), check the wiring and sensor. You can try cleaning it, you have to remove the two mounting screws. they are a torx, I don't remember what size.

Thanks, Jeep is going in for the radiator tomorrow, if it throws the code while it is there (it just turned off while I was coming back home) I think they can just take a look at it, if not, I will check it tomorrow. Thanks again.

It is on the body, follow the wire that's coming from the pedal to the engine, you will see the black plastic there.
It was a $40 fix. I took some pix long ago, will post.
