What causes the accelerator cable to stick on a 2002 sonata?

Here are several possible causes for a sticking accelerator cable on a 2002 Hyundai Sonata:

1. Lack of lubrication: If the accelerator cable is not lubricated properly, it can cause the cable to stick and become difficult to move.

2. Damaged cable: If the cable itself is damaged or frayed, it can cause it to catch and stick on various components within the engine bay.

3. Binding or interference: Something may be binding or interfering with the movement of the accelerator cable. This could be due to a kink or bend in the cable, a faulty throttle body, or a misaligned throttle linkage.

4. Worn grommets: The grommets that hold the cable in place may be worn out, allowing the cable to move around and causing it to stick.

5. Throttle body issues: If the throttle body is dirty or malfunctioning, it can cause the accelerator cable to stick.

6. Pedal assembly problems: Issues with the accelerator pedal assembly itself, such as worn bushings or a faulty return spring, can also cause the cable to stick.

It is important to have your vehicle inspected by a qualified mechanic to identify the exact cause of the sticking accelerator cable and to have the issue resolved to ensure safe driving conditions.
