Component Testing

  1. Ignition OFF, disconnect the harness connector of the TP sensor.
  2. Measure for 1,160-1,175 ohms between the 5-volt reference and the low reference terminals of the applicable TP sensor.
    • If the resistance is not within the specified range, replace the TP sensor.
  3. Measure the resistance between the signal terminal and the low reference terminal of the TP sensor. Sweep the TP sensor through the entire range. The resistance should vary between 1,530-630 ohms without any spikes or dropouts.
    • If the resistance is not within the specified range or is erratic, replace the TP sensor.
  4. Apply 5 volts and ground to the applicable terminals of the TP sensor, and measure the voltage between the signal and the low reference terminals. Sweep the TP sensor through the entire range. The voltage should vary between 4.3-0.6 volts without any spikes or dropouts.
    • If the voltage is not within the specified range or is erratic, replace the TP sensor.
