TPS sensor1? or TPS sensor2? - Camaro5 Chevy Camaro Forum / Camaro ZL1, SS and V6 Forums

I am trying to figure out which to tap into for an electronic TPS activation switch. (Nitrous Express switch number 15961) Looking at the shop manual, it seem there are two. I am not able to decipher why there are two and which one to use, or if it matters.

Any one able to help me with this?

I finally found a place in the service manual that describes this.

It seems there are two sensors so they they can check up on each other. On one, the voltage goes up on throttle opening-on the other it goes down. The ECU compares these as a check for faults.

The switch I have, says it will work either way-so it doesn't matter which one I use.
