DTC 8-2 (TP SENSOR HIGH VOLTAGE)
1. TP Sensor System Inspection
Turn the ignition switch ON and engine stop
switch " ".
Check the TP sensor with the HDS pocket tester
with the throttle fully closed.
Is about 5 V indicated?
YES – GO TO STEP 3.
NO – GO TO STEP 2.
2. TP Sensor Inspection
Check the TP sensor voltage is increasing unin-
terrupted when moving the throttle from fully
closed to fully opened using the data list menu
of the HDS pocket tester.

Turn the ignition switch OFF.
Disconnect the sensor unit 5P (Black) connector.
Measure the resistance at the sensor unit side.
Connection: White/Red – Green/orange
STANDARD: 0.5 – 0.7 kΩ (20°C/68°F)
Is the resistance within 0.5 – 0.7 kΩ?
YES – GO TO STEP 4.
NO – Replace the sensor unit with a new one,
and recheck (Faulty TP sensor)
4. TP Sensor Ground line Inspection
Turn the ignition switch ON.
Measure the voltage between the sensor unit 5P
