(d) Possible cause of malfunction: the malfunction is very serious, it is necessary to fix it
stay:
emergency mode, engine torque is limited.
DTC P2104: Engine over idle mode
(6) Mismatch between throttle position sensor #1 and accelerator pedal position sensor #2 (two input values mismatch);
DTC P2105 Forced Engine Stop
(4) Short circuit or open circuit in throttle position sensor #1;
(2) Short or open in the accelerator pedal position sensor No. 2 circuit;
(1) The engine control unit cuts off the fuel supply and turns off the ignition system, and closes
throttle opening exceeds a certain value (5%) while maintaining this state for more than 240 ms.
(4) Incorrect polarity of connecting the contacts of the two circuits of the power supply of the throttle valve;
(a) Prerequisites: The controller is connected.
(1) Faulty intake air pressure sensor;
(3) Faulty throttle position sensors.
tations);
(1) Short or open in the accelerator pedal position sensor No. 1 circuit;
(2) The engine does not respond when the accelerator pedal is depressed and can only run at approximately 800
rpm idle (including neutral and slow travel in first gear). When the first gear is smoothly engaged, the vehicle
may move at a very low speed, since the engine power is severely limited.
(b) Malfunction detection principle: a malfunction code is output when any of the following is detected
(1) Throttle works in protected mode, engine works in emergency mode, torque
(b) Malfunction detection principle: a malfunction code is output when both of the above are detected
(1) Strong external electromagnetic interference;
(d) Possible causes of failure:
(a) Prerequisites: The controller is connected.
(c) Emergency operation:
(a) Prerequisites: The controller is connected.

(b) Malfunction detection principle: a malfunction code is output when the following malfunctions are detected
(5) Throttle actuator malfunction (even with a short service life).
(c) Fail safe operation: Throttle operates in protected mode, engine operates in

(1) Short or open in the accelerator pedal position sensor No. 1 circuit;
(c) Emergency operation:
(3) Incorrect polarity of connecting the terminals of the two signal circuits of the throttle position sensor
(2) Short or open in the accelerator pedal position sensor No. 2 circuit;
(d) Possible causes of failure:
(2) Faulty throttle position sensor or actuator.
(4) Excessively strong external electromagnetic interference.
DTC P2106: Engine Performance Degradation
motor torque is limited;
below faults:
(2) Faulty intake pressure sensor;
(2) Throttle valve clogged with foreign matter (even if the service life is short)

(3) Accelerator pedal position sensor No. 1 and accelerator pedal position sensor No. 2 mismatch (two input
values mismatch);
