Opel P1113 port deactivation sensor signal low (1)
This Opel Astra-H has a too low signal for the Port Deactivation sensor. It is only 0,1 volts. Preferably you need 0,5 volts. This is because of wear and tear in the mechanism that works the valves in the inlet ports. Proper repair would require a completely new intake manifold. This is very expensive. In the next video I will show you how to fool the computer.
