14 BMW 530 throttle 1 and 2 double faults.

Throttle position sensor signal is inaccurate.

The main reason is that the signal of the throttle position sensor is inaccurate. You can use the computer to read the throttle position sensor and throttle position sensor 1 and 2 to see if there is any signal. If there is no signal, you need to test the plug connection on the throttle. If the wiring is ok, just change the throttle directly.
