2014 Aygo Bank 1 Sensor 2 Oxygen sensor

[D89]

Hi,

I had engine management, traction and TPS lights come on whilst travelling yesterday. Plugged the OBD reader in and it shows oxygen bank 1 - sensor 2 issue.

Where is this sensor located and what part would I need to replace it? 

Car is an MK2 2014 Aygo. 

Thanks

B1S2 is located at the bottom of the cat/manifold, what is the actual code you have ?

Also check the exhaust isn't leaking especially around any joins. 

I've never had a lambda sensor fail but both times the light came on with 2nd lambda sensor code on a previous vehicle it was a leaking exhaust join.

I'll have to plug it back in tomorrow down my friends as I forgot to get the actual code 😅

Thanks I will have a check when the weather improves 😊

The sensor is located underneath, just behind the front bumper.  You really can't miss it.

To gain access, you'll need to jack the front of the car up.

 

To remove the old oxygen sensor, I would suggest a 22mm ring spanner.  Cut the electrical cable, put the ring spanner on it, then hit the other end of the spanner anti-clockwise with a mallet or hammer.

For the sensor, use Bosch / Denso or NTK(NGK). E.g:
