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.
