The fault light of Chery A5 16 generator is on, so it is unreasonable to use the decoder as the signal of electronic throttle sensor 2.

There are two position sensors on the electronic throttle of the engine. Pin 4 is the signal line of the throttle position sensor 2 (corresponding to ECU 54 #); Check the wiring from electronic throttle position sensor to ECU for short circuit, open circuit or poor contact. If not, it should be an internal fault of the throttle.
