Component Testing

TP Sensor

1. Turn OFF the ignition.
2. Measure for 5,150-5,350 ohms between the 5-volt reference and the low reference terminals of the 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. Slowly sweep the TP sensor through the entire range several times. The resistance should vary between 2,500-6,800 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. Slowly sweep the TP sensor through the entire range several times. The voltage should vary between 0.6-4.7 volts without any spikes or dropouts.
   • If the voltage is not within the specified range or is erratic, replace the TP sensor.
