Exhaust Butterfly Valve Actuator Sensor Resistance
Connections: W lead [C] ←→ BK lead [D]
Standard: 4
6 kΩ

If the reading is out of the standard, replace the exhaust butterfly valve actuator.
If the reading within the standard, but the problem still exists, replace the ECU (see ECU Removal/Installation in the Fuel System (DFI) chapter).
