NOTE

Be sure the battery is fully charged.

Special Tool - Throttle Sensor Setting Adapter: 57001 -1538

Subthrottle Sensor Input Voltage Inspection


Subthrottle Sensor Input Voltage Connections to Adapter: Digital Meter (+) → W (sensor BL) lead Digital Meter (–) → BK (sensor BR/BK) lead

Input Voltage Standard: DC 4.75 5.25 V


If the reading is within the standard, check the output voltage (see Subthrottle Sensor Output Voltage Inspection).

If the reading is out of the standard, remove the ECU and check the wiring for continuity between harness connectors.

Special Tool - Hand Tester: 57001-1394

Disconnect the ECU and sensor connectors.

Subthrottle Sensor Input Voltage Inspection


Wiring Continuity Inspection ECU Connector [A] ←→ Subthrottle Sensor Connector [B] BL lead (ECU terminal 9) [C] BR/BK lead (ECU terminal 13) [D]

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) chapter).
