Need to troubleshoot a few obd2 code
I replaced apps and tps already but still getting limp mode. Looks like its a wiring/ shorts somewhere.

Code was p1121 p1120
Replaced apps.
Then code become p1121 p0121 p0120
Then clean ecu wiring a little bit, muck around with throttle body.

Now i get p1128.
i want to make sure wiring for apps, tps and tcm are all grounded and sending signal properly.

Need to get wiring diagram now. Thx
