- Turn ignition off. Measure resistance at component side between TP sensor connector terminals No. 1 (Black/Green wire) and No. 3 (Blue/Orange wire). 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 as specified, go to next step. If resistances are not as specified, replace TP sensor.
- Connect TP sensor connector. Turn ignition on. Backprobe and measure voltage between TP sensor connector terminals No. 1 (Black/Green wire) and No. 3 (Blue/Orange wire). With throttle fully closed voltage should be about .5 volts. With throttle wide open, voltage should be 4.1-4.3 volts. If voltages are not as specified, replace TP sensor.
