DTC 7-2: TP sensor voltage is high
1. Symptom reproduction test
-1. Connect the HDS pocket tester and clear the DTC
once. If the DTC can not be cleared, go on the trou-
bleshooting.
-2. Turn the ignition switch ON.
-3. Measure the TP sensor voltage with the HDS pocket
tester.
Is the measurement 0.08 – 4.92V?
YES –
Temporary failure (Disappeared)
NO –
Perform “2. TP sensor power line check”.
2. TP sensor power line check
-1. Turn the ignition switch OFF and disconnect the TP
sensor 3P connector.
-2. Turn the ignition switch ON. Measure the voltage
between the No. 3 (Brown/White) and the No. 1
(Green/Red) terminals of the TP sensor harness side
3P connector.
Is the measurement 4.75 – 5.25V?
YES –
Perform “4. TP sensor signal line open circuit
check”.
NO –
Perform “3. TP sensor power line open circuit
check”.
3. TP sensor power line open circuit check
-1. Turn the ignition switch ON. Measure the voltage
between the No. 3 (Brown/White) terminal of the TP
sensor harness side 3P connector and the engine
ground.
Is the measurement 4.75 – 5.25V?
YES –
Repair open in the wire between the TP sen-
sor and the engine ground.
NO –
Repair open in the wire between the TP sen-
sor and the ECM.
4. TP sensor signal line open circuit check
-1. Turn the ignition switch ON. Measure the voltage
between the No. 2 (Red/Black) terminal of the TP sen-
sor harness side 3P connector and the engine ground.
Is the measurement 4.75 – 5.25V?
YES –
Perform “5. TP sensor check”.
NO –
Repair open in the TP sensor and the ECM.
