What is the reason for Nissan Sylphy fault code p2 103?

Fault code: P2 103 Chinese meaning: throttle actuator A control motor circuit Gao Yingwen meaning: throttle actuator control motor circuit high category: fuel, air or emission control Detailed meaning: In electronic throttle control (ETC) system, throttle actuator is a stepping motor.

pay attention to

1. The stepping motor is used in low-speed situations-the speed per minute does not exceed 1000 rpm (0.9 degrees 6666PPS), and it is best to use it between 1000-3000PPS(0.9 degrees). Here, it can run through the reducer, with high working efficiency and low noise.

2. It is best not to use full stepping state for stepping motor, because full stepping state has great vibration.

3. Due to historical reasons, only the motor with the nominal voltage of 12V uses 12V, and the voltage values of other motors are not driving voltage volts.

The driving voltage can be selected according to the driver (suggestion: DC 24V-36V for 57BYG, DC 50V for 86BYG, and 80V higher than DC for 1 10byg). Of course, the voltage of 12V can be driven by other driving power sources besides 12V, but the temperature rise should be considered.
