I believe my TPS is going bad in my truck because of sudden shift outta gear and i was wondering what the ohm reading should be and what color wire is positive and what one is negative

 

back probe the tps wires i think its the middle one and the one closest to the firewall. i cant remember exactly but i think its like .4 with the key on, and then a smooth sweep up to like 4.xx at wot. look for dead spots durring the sweep of the gas pedal.

 

checked my manual. closed throttle key on is .35 to .9. and wot is 4.5

 

thanks ill have to borrow my friends multimeter sometime this week and check. nice vids on youtube
