I will try my best to help you.This may take some time to figure out.
Do you have a picture of your wiring?
There are two wires that almost look the same color. Did you cross them?
Customer: replied 1 year ago.
we wired the connector excactly how it is pinned at the ECM we also removed the coduit and tape as far back as we could to make sure on the colors and also to make sure they were not stuck together. we tried another throttle body but same codes return p-0121 and P-0221. it had originally codes those and these P-2176 P-0507 P0522. so we check the wiring to the ECM to throttle actuator and they were good so we replaced the ECM (at another facility since we cant program here ) ECM from dealer, now the y lost the pass key and it wont start at all, they tell us that it needs a pass key 3 1600.00.this is a bad situation for all of us ,
