2014 Vanquish O2 Sensor Help
Hi all,
I've been trying to figure this out but all I'm getting from AI is conflicting information and nothing solid in FB groups. I'm getting intermittent P0150 and P0132 codes. They come and go about every 75ish miles or so. What are the part numbers for the O2 sensors that I need? Are the Ford DY1401 that Aston1936 recommends in his video the right ones? Or perhaps Bosch 17014, or 15717? Something else? Is XC2F-9F472-B1A the correct OEM part number?
Thanks all!

I had/have the P0130 & P0150 codes so i swapped in a pair of (pre-cat, secondary bank) Delphi sensors last Feb., they only worked for a few months and the codes were back.
A trend i have noticed is that the codes pop up in city driving often, but on long trips over a few hundred miles - no codes.
So since i was starting my yearly maintenance i contacted Steve at Aston1936 and asked how it's been going since he replaced all 8 with the Dy-1401's, his replay was "great".
I ordered a pair of Dy-1401 to replace the Delphi O2 sensors.
The only other option i have found is from flyingspares. com in the UK, they state same as OEM
Upper is 1R12-39-10174-OEM ~$85
Lower is 1R12-39-10175-OEM ~$80
The XC2F-9F472-B1A is correct for the pre-cats, but has been replaced with 1R12-39-10174, post cat's are 1R12-39-10175

Thanks guys! I'll give it a go and hopefully this takes care of it. Will likely go with the 1R12s just cause it will be considered a business expense. The whole XC2F vs 1R12 was part of my confusion but the explanation above makes it all click for me. Thanks again,
