The accelerator pedal position sensor is mounted to the car's gas pedal and converts any movements into voltage. Once this is done, the check engine light should change by blinking slowly and indicate "Erasing ECU Memory". He has been working as a car mechanic for over 10 years, and the majority of them specialized in advanced car diagnostics and troubleshooting.
