Auto holding in 1st?

Hi guys, I have a JDM Fairlady TT and for its latest trick :smash: it has decided to start holding in first (while in drive) until you take your foot right off the pedal, then it will drop down. I have cleaned the plug from the TPS as it was green and corroded, this made some but very little difference. The chappy at Z world said something about 0.4V at the wires or something?????? PLEASE ADVISE. :(

    If you have a multimeter put it resistance and put it on the two terminals of the tps. Make sure its base voltage is 0.4 ohms resistance when the throttle pedal is not pressed. If not adjust it by slackening off the two bolts, screws and turn slowly until its 0.4
