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 (%)
The engine control module (ECM) calculates the value from the throttle position sensor. The value is calculated linearly from the throttle position sensor's output signal (0-5V) and indicates how much the throttle is open.
Approx. 6-14 % = idling (0% throttle angle, desired value).
Approx. 85-100 % = throttle fully open (100% throttle angle, desired value).
