Where is Santana 3000 accelerator driver angle sensor 2?

It may be that the signal of throttle driver's angle sensor 2 is too small to find its position.

Check the brake light switch.

It is a good idea to change the throttle valve. If you don't do it, try it. If the fault still exists after matching, the engine computer should be considered. Also, check whether the three wires in the throttle plug of the engine harness are grounded. The ignition pulse of the engine will interfere with the signals of other sensors. Check the ignition system.
