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.
Throttle Position (%)
Measurement range 0-100%.
The engine control module (ECM) calculates the value from potentiometer 1 for the throttle position sensor. The value indicates the throttle opening. If the engine control module (ECM) detects a fault in throttle position sensor potentiometer 1, the value from throttle position sensor potentiometer 2 will be used to represent the throttle angle. This presumes that the function of throttle position sensor potentiometer 2 is OK.
0 % = throttle shut.
100 % = throttle fully open. This corresponds to an opening angle of approximately 84 degrees.
HINT: Must follow the parameter "Throttle angle, desired value".

- • 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.
