Exhaust Shutter Valve Position Sensor Inspection: Notes
NOTE:
- The exhaust shutter valve position sensor is built into the exhaust shutter valve. When replacing the exhaust shutter valve position sensor, replace the TWC.
- The PCM increases the target engine speed for quick activation of the catalytic converter after a cold engine start. The PCM controls the exhaust shutter valve at the fully-closed position while the catalytic converter is activated quickly. Perform the exhaust shutter valve position sensor inspection with the engine cooled sufficiently (engine coolant temperature has decreased to equivalent of ambient temperature).
