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 Angle (%)
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 the throttle position sensor potentiometer 1, the value from the 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.
