2002 Ford F150

I am having a problem with my Ford f150 and I would like to know if anyone could help me figure out or tell me whats wrong with it. I recently put it on a computer and it gave me -P121 throttle position 1 sensor A inconsistent with map sensor, the truck is losing power whenever I drive it and I would like to know how to fix it or what it would take to fix it??

well I just changed the throttle control sensor in my pickup and its still acting up. I just ordered 8 new coil packs to put on it and after i unplugged the 1st coil I had oil in it. Can anyone tell me what has happened or is wrong with it?

I don't get the coil thing, just throwing parts at it?


as for the problem, get on autozone.com and look up the schematic, one wire is 5v input to the sensor the other two are outputs. circuit a codes mean that the voltage the pcm is seeing doesn't ever get to the 5v area, so the wire to it from the pcm is not making connection. The wire has a brake or something...
