Replace lambda sensor on V8 Vantage - but which one?
Discussion
Hello!
Just bought a 2010 Aston Martin V8 Vantage, 426HK a few weeks ago. The last couple of weeks I've kept getting an exhaust error message. A quick scan with the OBD gave me two error messages, P0133 and P0153.
I understad that this is related to the O2 lambda sensor. I've talked to a local workshop where I live, and they said there is two sensors. So what i'm basically trying to figure out is which one I need to replace. Anyone have any input?
I'm going to order the sensor and replace it myself. The price for one sensor here in Norway is £500 + replacement costs... eBay only charges less then £100, and it looks like an okay thing to do.

Wow, £500 crazy ...certainly they can be done DIY if you can get access under the car safely. I bought some off ebay and had a local garage change them for me last time, and it was only £100 per sensor

The codes refer to Bank1 pre-cat sensor slow response and bank 2 pre-cat sensor slow response. Its unusual for both sensors to die at the same time unless contaminated e.g. if non sensor safe RTV has been used during an engine repair, contaminated fuel etc. The other possibility is a wiring issue common to both sensors, possibly the heaters.
I have had my V8VR for 6 years now and replaced the upstream O2 sensors twice due to the P0133 & P0153 codes.
The first thing to do is erase the codes using your OBD reader and see how long the car runs for before the codes / message appears.
In my case after erasing the codes the message appeared every couple of days which was inconvenient having to erase the codes.
The DTC codes P0133 and P0153 are generally caused by the two upstream O2 sensors on the cat.
They are fairly easy to replace although I got a local garage to replace them the first time I replaced them, I bought the OEM AM sensors the first time (circa £100 each)
The second time they were replaced when my car was in an AM indy for a new twin plate clutch and they had removed the cats, so replacement was very easy and I think they just sourced a non OEM sensor (circa £60 each).
A tip the AM indy mentioned to me was to wind the O2 sensor cable anti clockwise prior to fitting so that when you screw the into the cat the cable is unwound to a natural position.
But erase the codes firstly using your OBD reader and see how long you get before the message appears.
The car should still run perfectly well, even with the dash message.

I cannot remember exactly if I got both DTC codes at the same time.
The first time I replaced both O2 sensors (just to be sure) and the second time I replaced just one of them, but the DTC appeared within a few days and the other one was then replaced and its been fine for over 18 months now.
The two upstream O2 sensors are at the front of the cat at the end nearest to the manifold I think.

Just to make sure, is the Passenger side on the left? It isn't always that way on forums Bank 2 is passenger side / cylinders 5-8
Sensor 1 is upstream cat
Sensor 2 is downstream cat
Also, I bought a lambda sensor, before I knew there were 4 of them, are they all the same? The one I bought was the type recommended on here or perhaps on 6speedonline, its a 1x NGK NTK Oxygen O2 Lambda Sensor OZA488-AM1 OZA488AM1 (0042), £58 on ebay

I fixed mine yesterday, very easy job (see my other post on how to do it.)
The genuine AM lambda sensors are different front and back because the wires are a different length, and the plugs are a different colour front / back. The plugs are the same fitting, just the colour is different.
