Hello!

Over the last week, I've popped an 0120 error code twice.

I think this is a TPS sensor code. Other than popping the check engine light, the truck seems to run fine (though it pops into 'limp home' mode until I turn on and off the ignition 3 times).

Do I need to replace the TPS sensor, or is ti possibly something else as well?? I think Conicelli has it for $40 or so.

Thanks in advance!

I've never heard of "limp home mode" on our trucks. Anyways, yes that code is for an issue with the throttle position sensor. If there is no problems with the ECM or wiring, then the sensor needs to be replaced.
