2003 Kia Spectra Base, AutomaticFACTORY OEM SERVICE PROCEDURE

Throttle Position Sensor: Spectra

  1. Turn ignition off. Disconnect TP sensor 3-pin harness connector. Measure resistance at component side between connector terminals No. 1 and 3. See Fig 1. 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 as necessary.
  2. 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). See Fig 1. With throttle fully closed voltage should be .3-.9 volts. With throttle wide open, voltage should be 4.0-4.4 volts. If voltages are not as specified, replace TP sensor as necessary.
