How to test a throttle position sensor (P0121, P0122) GM wiring integrity

Описание: What I am showing in this video is how to quickly test a throttle position sensor and wiring. No need to follow some engineer written flowchart that tells you to ohm the circuit for opens and shorts. (too time consuming)
All you need is a decent scan tool and a paper clip.

Symptoms:
check engine light (trouble codes P0121 and P0122)
hesitation
stalling

Fix:
replace faulty TPS

Tools used:
Graphing multimeter (Vantage MT 2400) but a regular digital multimeter would work
Scan Tool
