1.6 120 blue HDi - Failure P2202

[Piotr]

Hello everybody,

Yesterday I pluged in my intetface elm 327. I used first time application "fap".
Application found one error p2202. No errors on the car screen, no check engine icon.
Do you think the problem is with Nox sensor or application generated this error?

Hi,

P2202 : NOx Sensor Circuit Low (Bank 1),

how many miles?
what are the freeze frames associated with your default code?
check in the datalive if the value in volt is different from zero (to know if there is a short circuit to the ground).

on the Blue HDi you have a SCR catalyst just before the DPF, check that you don't have any error code related to the adblue (tank level, adblue injector...)

if you don't have any symptom, erase the code and see if it comes back.
good luck

Thanks you very much for your answer.

100400 km.
I can' attache the photo but there is written " heating of nox sensor".
On the Polish forum i received the answer that the error is due to FAP application I used on my mobile phone.

Next week I am pluging on the diagbox and check the errors.
