How do you repair P1507 and P0122?

Question

What parts and steps are needed to repair the cause of the P1507 Error Code and P0122

Answer 1

HI there

Both of these codes point to a problem with the throttle. The P0121 code is for the throttle position sensor. This could be causing issues that would result in the p1507 code. This code is for the idle speed actuator. Also mounted to the throttle body. I would replace the the TPS, clear the codes then see if the p1507 returns. If it does, then replace the ISA.
