Electronic Throttle Body Diagnosis

ETC, or electronic throttle control, has been used by manufacturers for over 20 years. Given the inherent danger of electronically controlling the throttle blade, manufacturers have used a number of approaches to validate system data before the ECU makes a control decision. While throttle body assemblies are typically robust, they still occasionally fail.
