VX Polo AXU FSi 2006 - NOx sensor range / performance, code P2201 #

Posted by Sam Green on March 22, 2011, 7:21 pm

Year of Manufacture *: 05/06
Engine Size and Code *: AXU fsi
( Optional ) ECU Type: modis
( Optional) Fault Codes: P2201

Hi all, in in need of a little tech info on testing the Nox sensor circuit on the above mentioned vehicle, due to a lack of wiring diagrams and pin config i am struggling to make sense of what i am getting on the scope. This model does have the Nox sensor controler and all i can find for that is voltage supply checks, all ok.
Any help would be appreciated, thanks

Hi Sam
What readings are you getting in live data? Ive just had a NOx sensor problem on a golf 1.4 fsi.

Hi jamie. I can't get any live data readings on the sensor with modis. What readings are you getting?

Hi Sam
There is a post further down the page on a golf 1.4 fsi with the readings on there. I was using kts and could get live data. Does the modis have expert mode and use the measuring blocks? HTH.
