Exhaust Butterfly Valve Actuator Sensor Input Voltage Inspection


Input Voltage Standard: DC 4.75 5.25 V


If the reading is within the standard, check the output voltage (see Exhaust Butterfly Valve Actuator Sensor Output Voltage Inspection).

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

Disconnect the ECU and sensor connectors.
