Corolla can't get up at the speed of dry roar with double engines.

1. If the throttle body and accelerator pedal are damaged, you can first measure the following throttle body harness for problems. Generally, the definition of throttle line 6 is: two motor lines, two signal lines, one sensor for power supply and one sensor for grounding.

2. Turn on the ignition switch, plug in and measure. The voltage of two motor lines is the same, and a 5V power supply; One is 0V grounded, and the voltage of two signal lines is not lower than 0.2V (otherwise it may be reported as low voltage) and not higher than 4.8V (otherwise it may be reported as high voltage), and the sum of them is equal to 5 V.. If the measurement result is quite different from the above, it is that the throttle body itself is damaged, the line is virtually connected and the computer version is damaged.
