Ford forest suddenly couldn't feel the accelerator pedal.

Hello, this needs to be checked, whether the plug of the throttle position sensor is loose, whether the line is open, and whether it is in poor contact. It needs to be measured and checked with a multimeter to ensure that the line connection is reliable and normal. If the line is normal, you need to clean the throttle and maintain it in time to ensure smooth, comfortable and safe driving. Thank you.
