Does the throttle body need to be recalibrated after cleaning?

[MacElliana]

Recalibration is not required after cleaning a cable-operated throttle body, but it is necessary after cleaning an electronic throttle body. Below is more information about cable-operated and electronic throttle bodies: 1. Cable-operated throttle: The accelerator pedal is connected to the throttle via a steel cable. Pressing the pedal directly controls the throttle through the cable, similar to a handbrake cable. The accelerator pedal structure is relatively simple, purely mechanical, with no plugs or wires. 2. Electronic throttle: Matched with an electronic accelerator pedal, which is a potentiometer connected with multiple wires. The pedal's movement is converted into electrical signals sent to the ECU. 3. Cable-operated accelerator pedal: Since it directly drives the throttle and has friction resistance from the cable and tube, the pedal feels slightly heavier. 4. Electronic accelerator pedal: The structure is more complex, with an internal potentiometer, making it lighter to press with consistent resistance throughout. The electronic pedal is precise with no dead zone; even a light touch can increase engine RPM.
