Ok here is my problem started about 6 months ago i have a reduced engin power light and ses light coming on. engine idles slugishly and dies at stop lights got the codes read and ended up with a p1680 now i looked that up in these forums and im finding that i need to read the wires on the apps and on the tps already cleaned the throttle body replaced fuel filter air filter and still dies. back to the reading wires though im looking for a wiring diagram that is going to tell me what wires to read and what they need to be at i noticed in one of the forums it was anything below 450 ohms is good to go anything above needs a new throttle position sensor or one of the sensors or a pcm update or replacement basically im just wondering how to go about fixing it myself without a. going to a dealership and b. forking out a butload of money last part of my vin # 446173965

the pedal sensor and throttle body are main items here. the fly by wire system is at fault. you will need a scan tool to read the readings of the sensors to verify they are working.
