O2 Sensors.. Before I go out and buy some, can someone confirm what type the oxygen sensors used with the 2006/7 P59 PCM are?
I'm assuming they're standard zirconia 4 wire 0-1 volt, but I've fallen foul of that assumption with other vehicles before that actually used titania sensors.

So nobody knows then? Answering my question essentially saying “you need to find the type out” isn’t exactly helpful... that’s what and why I’m asking in the first place...
the P59 will either use zirconia or titania type and will have done for the whole design run. Delphi wouldn’t design two near identical ecus with entirely different lambda hardware. It would be major re engineering for no gain.
If anyone knows for certain, I’d appreciate knowing.

Nobody cares whether an O2 sensor is zirconia or titania. When one needs sensors they are ordered for the car in question. Where was your P59 sourced? You are looking for the long way around in searching for O2sensors.

jesus dude you want me to ******* put them in for you too? fwiw i havent seen a titania sensor for gm product that wasn't factory turbo or sc'd ...hence why they cost $40 instead of $100

I don’t know what the ecu is from. It came with the engine. If I knew, that would be a start, but it would still be difficult as it’s unlikely they would have specific O2 sensor data because information over here is limited. If I knew, I would already have the answer so wouldn’t have to ask what is a really simple question to which someone either knows the answer or they don’t. That’s why I’m asking in a forum.
The only GM products we get in the U.K. are/were Vauxhall and a lot of those did use Titania sensors.
The comment “nobody cares” seems a little strange. I need to know which type it is because only one type will work with the ecu.
Most cars use zirconia type as they are much cheaper to make. However, vehicles used off-road have a higher likelihood of using titania sensors as the lack of a requirement for a free air reference means they can cope with being fully submerged in wading scenarios.
The engine is an iron block which suggests it’s likely from either an Escalade or a Silverado, both off-road vehicles, hence a higher likelihood of finding titania sensors.
Does anyone have a p59 ecu equipped vehicle to hand? If so could they tell me what colour wires are on the O2 sensor? There will one or more of the following : - Black, White, Grey, Yellow, Blue and Red.
