Peugeot 3008 front parking sensors.

Hi all! Ive a problem with my front parking sensors on my peugeot 3008 2015 1.6D allure. I have it hooked up to diagbox and it comes up with an error on FBC2. I think ive identified this sensor as being in the drivers side fog light. All the sensors have been replaced with genuine sensors and the error remains. Ive cleared the error and restarted and its immediately detected again. Ive looked the wiring around the connector and theres no corrosion on the end. Ive stripped some of the insulator from the wires to check for corrosion and it seems fine. I have tried piggy backing off a working sensor and nothing changes. I have rear parking sensors as well and if i knock off the front ones with diagbox, the system works. What else could I try please to stop the parking assistance fault error please? Im thinking maybe purchasing a new loom but does anyone know where these sensors plug into?

Any assistance would be greatly appreciated 🙂

Hey @Foxtrot0mega, that sounds like a really stubborn fault, especially after you've already replaced the sensors and confirmed the FBC2 error with Diagbox. You mentioned checking the wiring around the connector—have you been able to test the continuity of those wires any further back along the loom? Letting us know what you find might help someone pinpoint where the signal is getting lost.

Hey! Thanks for taking the time to answer my question. How would you go about checking the continuity of the cables because I'm unsure as I've never done on a car before.😀
