Lexus ex350 doesn't respond when you step on the gas pedal. What happened?

If the throttle tachometer does not reflect, the throttle position may be 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. The maintenance station should carefully test the vehicle, read the relevant data through the diagnostic instrument, find out the cause of the fault after analysis and judgment, and then carry out maintenance.
