Resistance Inspection
•
Turn the ignition switch off.
•
Disconnect the exhaust butterfly valve actuator sensor
connector (3 pins connector) [A] (see Exhaust Butterfly
Valve Actuator Sensor Input Voltage Inspection).
•
Connect a digital meter [B] to the exhaust butterfly valve
actuator sensor connector.
•
Measure the exhaust butterfly valve actuator sensor re-
sistance.
