LS2 DBW throttle issue

I had around 150,000 miles on my engine when it went bad. I replaced the throttle position sensor on the throttle body and that fixed the problem.

I had around 150,000 miles on my engine when it went bad. I replaced the throttle position sensor on the throttle body and that fixed the problem.

I pulled the code and it was p2135 “throttle/pedal position sensor/switch “A”/“B” voltage correlation. I started to pull apart the LS2 silver blade where the throttle position sensor is and realized very quickly that was a bad idea and was told you can’t replace just that sensor but you have to replace the entire TB. Before I go and buy a $500 throttle body is there anything else I need to/should check? Thanks again
