This seems to be a common issue when DP's are installed. The O2 sensors are easily damaged if not disconnected first. My guess is the O2 sensor got damaged during DP install (happened to me) and needs replacing.

Sorry to bring this up after nearly 2 years, but im struggling with the same codes after DP install.
Checked the fuses, wiring and replaced the power distribution board but still getting code 1b5202 which I believe is cause of heater faults on all 4 O2 sensors. Potato's, did you ever find the solution to this fault? |

Hey sorry old post so when you replaced the Integrated Supply Module, that completely fixed everything? So you had no more o2 sensor codes/and no cel? I have these same exact codes and Ive been struggling to find the fix |

Will replace the O2 sensor part 11787848486 after next week. That should fix it. |
