Throttle Position Sensor: Sorento
- Turn ignition off. Disconnect TP sensor 4-pin harness connector. Measure resistance at component side between connector terminals No. 1 and 4. See Figure. With throttle fully closed, resistance should be 3.5-6.5 k/ohms. If resistances are as specified, go to next step. If resistances are not as specified, Adjust or replace TP sensor as necessary.
- Connect TP sensor connector. Turn ignition on. Backprobe and measure voltage between TP sensor connector terminals No. 3 (Red/Black wire) and No. 4 (Brown wire). See Figure. With throttle fully closed voltage should be .3-.9 volts. With throttle wide open, voltage should be 4.2-4.7 volts. If voltages are not as specified, Adjust or replace TP sensor as necessary.
