Function Explanation (DTC Detection Outline)<\/p>\n

\u2022 The PCM calculates the target opening angle appropriate to the engine conditions relative to the actual opening angle based on the exhaust shutter valve position sensor signal and provides feedback to the exhaust shutter valve control.<\/div>\n
\u2022 With the preconditions met, the PCM verifies the conformity of the actual opening angle relative to the target opening angle of the exhaust shutter valve. If the actual opening angle does not conform to the normal determination range relative to the target opening angle during the malfunction determination period ( approx. 5 s<\/span>), the PCM determines a malfunction in the exhaust shutter valve and stores a DTC.<\/div>\n
