So based on this thread: http://www.mustangevolution.com/forum/t25676
I went out and purchased a new TPS and replaced it hoping that it would fix the knock I have had since I basically first bought the car.
Well here is the funny thing. Before I changed the TPS I was getting no code about the TPS. Well tonight I replaced it with a brand new one and cranked it up and at first I thought the knock was gone. I even did an amazingly awesome dance.
However after taking it out to drive the knock slowly came back. The thing is now the knock is quieter where it was louder before and louder where it was barely heard. Also it feels as if my shifts are off now.
So now I am getting a TPS error code p0122 using both Autozones scanner and my SCT Xcal2. My question is, why is my brand new TPS sensor throwing a code? What does Circuit Low Input mean and how do I fix it?
Does the TPS need to be calibrated? Am I missing something else?
I do appreciate any help on this. I want to fix this.
