Hi, hoping someone can help and steer me in the right direction.
I had 2 fault codes appear on my Insignia 2016 (170) Elite Nav.
P220B - NOx Sensor Supply, Voltage Circuit Bank 1 Sensor 2
P22A7 - NOx Sensor Heater Sense, Circuit Range/Performance Bank 1 Sensor 2
I reset the codes and took it for a blast down the motorway for 40 miles in 4th gear at 3,000 revs to see if it would clean up the sensor. Only the P22A7 code has returned so not sure if it has solved the problem with the other code or not.
I'm guessing I just need to replace the sensor but finiding it difficult to track down the part reference code so I can scour ebay for a decent deal, don't want to buy the wrong one.
Can anyone help or advise?
Thanks in advance.
Phil
