If you have Twinport engine, P1113 error meens "Port deactivation position sensor circuit high/low voltage".
Sensor is located under inlet manifold. Whet you remove inlet manifold you'll see "manifold flange" which has port deactivation mehanic activated by vacum pump. Sensor sit on the other side and it's similar to TPS in older Z16SE engine, but it's not same sensor.
