No tps signal Last night at track my car began to act up. Per HPtuner the TPS is not being see. I replaced the TPS today and trace the appropriate voltage back to pin 24 on the harness that goes to the ECM. Im left with ECM as the problem I believe. The voltages measure as expected on signal wire all the way back to ECM harness. The errors are p1121 p1122 p0121 and p0122 which all reference the TPS sensor. In HPtuner the TPS position is not see at all. Assuming the ECM is at fault how do it address it. Any help is appreciated, thank you.
The vehicle is a 2000 Trans Am LS1 if there is any pertinent info I missed let me know.

If you are sure that the TPS and wiring is good including the pins on PCM and connector, then the PCM is damaged and need to be replaced.
They can be repaired, you can look for a automotive electronics repair shop and tell them that the TPS circuit is bad, it should be easy.
