Nissan's new bluebird, which has just been mentioned for more than ten days, has no response when stepping on the gas pedal. What's going on here? Could it be a quality problem?

If the throttle tachometer does not reflect it, it may be that the throttle position is faulty. For electronic throttle, the pedal position sensor and throttle position sensor or their circuits may be faulty. Of course, it may also be related to the signal difference of other sensors such as air flow meter. It is suggested that when you go to the maintenance station, you should carefully check the vehicle, read the relevant data through the diagnostic instrument, and find out the cause of the failure after analysis and judgment.
