Exhaust Butterfly Valve Actuator Resistance
Connections: P lead ←→ GY lead
Standard: 5 
200 Ω (for reference)
If the reading is 0 or infinity (∞) Ω, replace the exhaust butterfly valve actuator.
If the reading is in specification, remove the ECU and check the wiring for continuity between main harness connectors.
Disconnect the ECU and actuator connectors.
Wiring Inspection ECU Connector [A] ←→ Exhaust Butterfly Valve Actuator Connector [B] W/R lead (ECU terminal 45) [C] W/BL lead (ECU terminal 46) [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).
