Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Structure and inner electrical connection
The accelerator-pedal module functions with induction. The two sensors receive separate 5-volt power supplies from the engine-management control unit, to which they also have separate earth connections. The electronic processing circuitry generates analogue voltage signals, reflecting the accelerator pedal's position, for use by the engine-management control unit. The sensor signals are transmitted to the engine-management control unit separately.

When to See a Mechanic
Stop DIY work and contact a certified mechanic immediately if any of the following apply:
- • You smell fuel, burning insulation, or see smoke.
- • Brakes feel soft, pull hard to one side, or make grinding noises.
- • The engine overheats, stalls repeatedly, or misfires under load.
- • You are missing required tools, torque specs, or safe lifting equipment.
- • You are not confident in the next step or safety outcome.
