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.
Sensor Inspection
- Disconnect the throttle position sensor connector.
- Measure the resistance between terminals 2 (sensor ground) and terminal 3 (sensor power).
Standard valueΒ : 0.7~3.0 kΞ©
- Connect an analog ohmmeter between terminals 2 (sensor ground) and terminal 1 (sensor output).
- Operate the throttle valve slowly from the idle position to the full open position, and check that the resistance changes smoothly in proportion with the throttle valve opening angle.
- If the resistance is out of specification, or fails to change smoothly, replace the throttle position sensor.
Tightening torqueΒ
Throttle position sensor:
1.5~2.5 Nm (15~25 kg.cm, 1.1~1.8 lb.ft)
