Code 22 does not have anything to do with the ESC

First thing is to check and see what code is in the memory. Use a link below if you do not know how to read the codes without a scan tool.

Then clear the code.

Verify the code is cleared.

Drive the vehicle and see if the code returns.

Code 22 can be set by a bad TPS or a poor connection to the TPS.
Have you moved the throttle stop screw?

If it is modified from what came stock from the factory, let us know that too.
