Yes indeedy - I would guess it will have an incorrect transition from idle to cruise. The TPS will zero itself down to 0.48v. Anything lower and a code is thrown.
Say your TPS is actually at 0.30v. The lowest the PCM can go is 0.48v, so it will not read that the throttle is depressed until you are pressing the pedal enough to get to 0.48v.
I'd backprobe the sensor with a volt meter to verify what it is reading and replace if necessary.
This is strange. I just check the TPS voltage - KOEO - and it was at .96v and goes up to 4.7v when opening the throttle blade. So why am I getting the 122 code? Strange.
