2017 Peugeot 2008 1.2 TPMS/External temp issues

[Hekmeddun]

Hi I have a errors started with external temp sensor , auto brake failure, tire pressure check failure and last having serious shaking while accelerating from 0 km/h.
Electrician checked and fault many errors in diagnose. He physically checked abCI box under bonnet and found losen power connection. He tightened connection. Accelaration is fine now. Power was not flowing inside car due to loose screw in BCI. You can check it by your self.
BR,
Mehmet

Most of these relate to electrical issues (regardless if one or more works ok), as they can work on the same CAN network, so while one thing works, another may not. It really needs somebody that can test CAN wiring using the appropriate testing equipment to track down the fault (s).

The Tyre under inflation detection fault means the ESP system is not detecting that you have reset the tyre pressures from the touchscreen (or however you are supposed to reset them on your vehicle). On mine it is via the touch screen - but the signal is not getting through - which again tells me there is a communications fault on the network. It needs investigation by an Auto electrical technician with the correct equipment.

SOLVED

My local independent citroen/peugeot service found bad connection in door socket (the one which is in chasis), not the greatest place to work, but they did sort this out.

Thank you for all your help!

Great, no problem, thanks for taking the time to update us.

If I send you my VIN, can you tell me if it is indirect or ESP that is affected by the wrong Temperature Readings? It reads -42 degrees and the heating comes on full blast. The dealer says as it is an intermittent fault, there is nothing he can do.

VF3**************[VIN obfuscated, can be read by forum staff] Please would you tell me if I have an indirect TPMS system?

[GiveMeABreak]

Indirect - so no sensors on the wheels, system uses the ESP system to calculate under inflation or a puncture, which is why it must be initialised every time you inflate one or more tyres....

Found my problem to be dirty connections on connector blocks in car door took them all apart and cleaned them with contact cleaner bingo back to normal mine was reading -40 and already replaced external temp sensor 2017 1.2. Allure

Afternoon, seems i have a very similar issue and looking to get a hand, i have a 2014 Peugeot 208 and all around the same time I've had the tyre pressure system fault warning, my outside temperature displays nothing and both electric windows don't work, I feel this will be a wiring issue from everything I've read just haven't got around to getting the door card off yet. Would it be worth replacing the air temperature sensor anyway while I'm working in the car and could anyone link to a recommended replacement part. Cheers
