How to test your TPS sensor

TPS sensor check on a 97 integra

First locate your throttle position sensor which should be on the side of your throttle body. You’ll then see a clip like this and will need to probe the red wire with your multimeter. Grounds can be either the battery or any solid chassis point

Next we’ll want to check closed and open voltage. Closed should be roughly .5v and open roughly 4.5v. MAKE SURE the voltage is sweeping as you open the throttle. large jumps in voltage or a cheap non oem tps can cause driveability issues.
