P1342 Diagnostic Error in Peugeot 407 3.0 V6 - Manufacturer Definition and Solutions

Model: Peugeot Fault Code: P1342 Posted: 2020-06-02 09:33

Hi everyone, My Peugeot 407 3.0 V6 is experiencing a performance issue, and the OBD2 scanner has detected a P1342 diagnostic error code as defined by the manufacturer. This code relates to the oxygen sensor circuit malfunction in Bank 2, Sensor 2 (post-catalyst). I'm looking for accurate information on what this means, potential causes, and how to resolve it. Can anyone confirm the official Peugeot definition of P1342? Are there common fixes or diagnostic steps for this issue specifically in a 407 3.0 V6 model? Thanks for your help!
