NOX sensor

[Guanock]

Hi. I have apparently got an intermittent/erratic nox sensor 2 bank 1.

Anyone point me to the location of this sensor please.

Hi. You should easily find it following the exhaust pipe. I've attached a pic

Thanks for that, I was not sure if it was the first or second sensor. They are silly money!!!

Geoff,
Did you get an engine warning light and text on the dashboard?

[Guanock]

First to light up was the diagnostic engine light, followed shortly by the spanner and a message on the speedo dash panel. It also defaulted the centre display to a map showing the nearest Citroen dealers.

I topped up with 7 litres of adblue and after about 5 miles all warnings disappeared.

The OBD fault code was P22A2 which apparently is a fault with: NOX 2, bank 1. Circuit intermittent/erratic.
