On my 51 reg 3.2 Elite, the EML illuminated on the motorway, but the actual running of the car hasn't been affected. It has done 101k.
My local VX dealer kindly plugged in the Tech2 with the following faults codes -

P150 (9)
o2 slow response
Bank 2 Sensor 1
Bank 2 Sensor 2 (x2)

The codes were cancelled, but the light came back on after about 10 miles and I have noticed the odd 'wiff' of fuel from outside the car.

I am assuming that Sensor 1 is the front o2 sensor / Lamda sensor on Bank 2 and is the likely culprit.
Is it possible that this faulty o2 sensor is causing the codes being thrown up for Bank 2 Sensor 2.
Incidentally, I have read the very informative fuel trim / cat efficiency topic with great interest.
 
Could anyone explain what the code P150 (9) refers to, and also which is Bank 2 ?!!!! Nearside or offside of the car???

Would replacing the front o2 sensor be the first thing to do to possibly cure it? I have also read somewhere that the recommended interval for changing the front o2 sensors is 100k?

Thanks in advance,
John

Bank 2 is the nearside 2-4-6 bank,sensor 1 is the one nearest the manifold,sensor 2 is the after cat sensor

Dont immediately suspect the sensor. It needs proper diagnostics.
