1) Ensure ignition is OFF.
2) Remove rear of ECU plug cover and insert plug back into ECU.
3) Turn ignition back on (do not start engine)
4) THROTTLE CLOSED:
4x4: Check for DC voltage less than 0.5V between pins 11 and 17.
5) THROTTLE FULLY OPEN:
4x4: Check for DC voltage greater than 4.5V between pins 11 and 17.

thanks for that jon,so if i have more than 0.5 on throttle closed,i can then lower it by slackening the tps itself and turning it untill i get 0.5?Nice one.The problem i've got is getting my exhaust emissions down,so i am checking all the settings first.Im running closed loop and i cannot get the emissions lower than 3.5% should be0.8%

at idle the voltage needs to be <0.35V - from experience between 0.25V and 0.3V is the best bet to get reliable idle position recognition.
