17-54 SELF-DIAGNOSIS SYSTEM
Gear Position Sensor (Service Code 25) (DTC P0914, P0917)
Measure the output voltage with the engine stopped and
with the connector joined.
Turn the ignition switch on.
The figure shows 55°.
Rotate the gear position sensor, confirm the output volt-
age will be raise or lower.
Turn the ignition switch off.
If the reading is out of the standard, replace the gear po-
If the reading is within the standard, remove the ECU and
check the wiring for continuity between main harness con-
Disconnect the ECU and sensor connectors.

If the wiring is good, check the ECU for its ground and
power supply (see ECU Power Supply Inspection in the
Fuel System (DFI) chapter).
If the ground and power supply are good, replace the ECU
