How to Fix P0402 and P0101 Codes in 2011 Jeep Grand Cherokee CRD
I own a 2011 MY12 Jeep Grand Cherokee CRD and am currently experiencing diagnostic trouble codes P0402 and P0101. Can anyone provide guidance on how to diagnose and resolve these issues? Thank you for your help.
Begin by inspecting the vacuum lines connected to the Diesel Particulate System (DPS), which is part of the EGR system. A leak in this area can trigger both P0402 and P0101 codes. If no leaks are detected, refer to the official troubleshooting guide for these specific trouble codes available on this forum.
