Throttle Position (TP) Sensor: Sephia

Turn ignition off. Measure resistance between TP sensor connector terminals No. 2 and 3 (Blue/White wire and Blue/Orange wire - component side). With throttle fully closed, resistance should be 1.6-2.4 k/ohms. As throttle is opened, resistance should smoothly increase linearly to 4.1-4.3 k/ohms at wide open throttle. If resistances are not as specified, replace TP sensor.
