43 TPS (Throttle position sensor) out of adjustment OR knock sensor signal error OR low voltage at electronic spark timing control.

Um, code 43 is usually a bad knock sensor, located as a coolant plug down by the starter. It's either that or there is an ECM error.

The guy above is referring to a different code...
