  • I just changed the throttle on my car. The idle RPM will not relearn and now I got the P0442 code. Help please?

  • The P0442 should have nothing to do with throttle body, unless you left a hose disconnected near the throttle body. Why did you replaced the throttle body?
    You could try disconnecting the car battery for more than 30 min and then try the relearn procedure again.
