2001 Saturn (Black, half car)

TPS hook up


The TPS is located on the back side of the throttle body and it is a varying analog signal. You do not need to start the car to test this sensor - Do a KOEO and then a full sweep of the TPS to watch the signal vary on your scope screen. You will hook your red scope lead to the green signal wire and your black scope lead to chassis ground or neg bat.
