Ok so i was reading the wrong sensor there are 2 sensors on the TB one on top and one on the side of the TB toward the front of the car... i was reading the one on the top of the TB (not sure what sensor that is.. but im guessin the Tps sensor is the one on the side...) can someone let me know please... also what is the differance between checking the reference voltage from the pcm im asuming the grey and black wires coming out of the pcm? and the tps signal voltage? im guess thats the females in the sensor? once i get these answer ill repost the to correct readings.. thanks again guys sorry its been awhile since ive worked on a car haha
