17-80 SELF-DIAGNOSIS SYSTEM
Quick Shifter Sensor (Service Code 3E) (DTC P0826)
Quick Shifter Sensor Output Voltage Inspection
Measure the output voltage at the quick shifter sensor in
the same way as input voltage inspection, note the follow-
Disconnect the quick shifter sensor lead connector and
connect the measuring adapter [A] between these con-
Main Harness [B]
Quick Shifter Sensor [C]
Digital Meter [D]
Special Tool - Measuring Adapter: 57001-1700
Quick Shifter Sensor Output Voltage
Connections to Adapter:
Digital Meter (+) → Y (sensor G/W) lead
Digital Meter (–) → BK (sensor G) lead
Measure the output voltage with the engine stopped and
with the connector joined.
Turn the ignition switch on.
DC 0.35 4.65 V
By shifting up (down) the gear, confirm the output volt-
age will be raise (drop).
Turn the ignition switch off.
If the reading is out of the standard, check the quick shifter
sensor resistance (see Quick Shifter Sensor Resistance
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.
Wiring Continuity Inspection
ECU Connector [A] ←→
Quick Shifter Sensor Connector [B]
ECU Terminal 46 [C] ←→ Sensor Terminal [D]
ECU Terminal 38 [E] ←→ Sensor Terminal [F]
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
(see ECU Removal/Installation in the Fuel System (DFI)
