Defect
On diesel engine vehicles, the solenoid valve that controls the exhaust gas recirculation (EGR) cooler bypass valve uses an exterior resin material that was not properly selected for the operating environment. The large difference in thermal expansion between the resin and the internal coil wire subjects the coil wire to repeated excessive stress. Continued use may cause the coil wire to break, illuminating the engine warning light and stopping EGR control via the failsafe mode. In the worst case, nitrogen oxide emissions may increase.
Corrective action
On all vehicles, replace the solenoid valve with a corrected part.

状況
ディーゼルエンジン車の排気ガス再循環（ＥＧＲ）クーラーバイパスバルブを制御するソレノイドバルブにおいて、当該バルブの使用環境に対する外装樹脂材の選定が不適切なため、内部のコイル線との熱膨張差が大きく、コイル線に繰り返し過大な応力がかかることがある。そのため、そのまま使用を続けると、コイル線が断線し、エンジン警告灯が点灯するとともに、フェールセーフによりＥＧＲ制御が停止し、最悪の場合、窒素酸化物の排出量が増加するおそれがある。
改善措置
全車両、当該ソレノイドバルブを対策品と交換する。
