I just replaced the downstream sensor with the NTK version of the plug for the Escape. While the O2 sensor worked like a charm, the leads were a bit short (the plug still worked though). So I just spliced the old plug with the new sensor and wrapped it with heat reflective tape. So far the sensor has been reading correct voltage, so all seems to be good, but I just wanted to let everyone know that the wires were a bit short on this solution.

 

I appreciate all the help! I'm going to run by a local parts store in the next few days and get a couple of NTK 22009 sensors and put them in. $30 each, so I'm not out much if they don't work. I'll report back once they're installed.

 

Hey guys,

Perfect timing, I just heard back from the NGK reps in both USA and UK as I am getting ready to replace mine as well.

I am upgrading the manifolds, cats, xpipe, and tune which would require me to have longer O2 sensors. My options were to either buy harness extensions or replace the O2 sensors with longer cords.

My O2 sensors do not need to be replaced, but I heard its a pain to get to once bolted back up. It would be easier to deal with when swapping out the exhaust components. Thus, I reached out to NGK and got the exact match.

Unfortunately, they do not sell the 1:1 replacements here in the USA, but there are sellers in the UK willing to ship. I reached out to the UK NGK division and got their response. See below.

"Sorry for the short delay in response. The query was sent via our USA website, so it was returned to the UK via our European HQ in Germany!

The OE part numbered sensors you enquire about are supplied to Aston Martin by us, NTK. We have recently carried out some lambda sensor consolidations in the Aftermarket and as luck would have it, the latest NTK numbers quoted as cross referencing from the OE part numbers do have a longer lead! Please see below:Upstream: 6G33-9F472-AA. Aftermarket number OZA488-AM1, 0042, lead length 439mm - superseded to OZA816-EE1, 95598, lead length 810mm.

Downstream: 6G33-9G444-AA. Aftermarket number OZA381-AM1, 1707, lead length 650mm - superseded to OZA836-EE13, 92107, lead length 950mm.

The sensors come with any necessary cable ties to neatly bind to the length you require (both still have the same internal structure specification and correct connectors for the vehicle installed).

I hope this answers your questions. "

When talking to their techs, not all O2 sensors are made the same and just bc the connectors work does not mean you will not have issues with readings down the line.

Hope this helps. I will be going down this route and since they are much longer, should be a good option for 1) replacement 2) work with the new mods.

 

Thanks @V8Cdrew. I would say that your communication with NGK/NTK calls into question the assertion that the front and rear O2 sensors are exactly the same, with different wire lengths. I'm still planning to pick up 2 NTK 22009 sensors and install in the downstream location to see how they perform. Upstream I'd be more cautious about as they relate directly to fueling.

 

Best of luck. If it works, report back as that is another option. Im not sure what you mean that they stated the front and rear are exactly the same.

 

I went to pick up the 22009 sensors this morning, and found that they are too short for the downstream sensors on the car. They look to be the right length for the fronts though.

 

I spent time on the phone this morning with NGK/NTK USA. They didn't have any way to reference OE or NTK EU parts. That said, I was able to provide them with part 22009, which seems to be the correct sensor and connector, but with wiring that is too short. They took that information, and provided part 22106, which has the correct wire length for the downstream sensors. They are now installed in the car, and seem to be good after a couple of shorter drives. I'll keep an eye on things once all emissions readiness monitors pass, and report back. I paid $90 USD for the pair. I'd post pictures, but they can't be posted from my phone as an HEIC. If I find the patience to convert them later, I'll post them.

 

my understanding of the O2 sensors is that both sensors record the amount of O2 passing by them and the amount recorded by the second (downstream) one is subtracted from the amount recorded by the first (upstream) one and the difference is used to measure the efficacy and/or health of both. if that's true, then it would seem likely they they are the same.

...can't say for sure, but i'm pretty sure i read that somewhere. anyway, if you google, "are both oxygen sensors the same" the first response indicates that it's true.

 

Follow up here, NGK 22106 has been solid for rear O2 sensors over the last 110 miles. I hooked my NT530 up to the car today and there are no pending codes, and all O2 sensor readiness checks have passed. At $90 for the pair, I'd say this is a win.

 

Final update - A couple of hundred miles on the car, all readiness checks completed, and the car has passed emissions as well. NGK 22106 will work for the rear O2 sensors, at least for my 07 V8 Vantage.

 

NGK 22106 has a round plug and will not fit. I just bought one (happily only $36 inc shipping to US) from eBay and, after jacking up the vehicle, found that it will not work. Going down further in this thread people start talking about NGK 22009s. I will try that next after I send back the 22106s as it looks like these have the correct plug. Im at a complete loss to why a few folks are saying these 22016s work on a 2007 AM V8V.

 

My bad! The plug on the car is also round in shape. It just doesnt look like it until after you pull it clear. NTK 22106 seems like it will be fine after all.

 

I came back to this thread specifically to state that mine were round and the NTK 22106 worked like a charm. Glad that you'll be able to use them.

 

yes, no problem so far. Had a pretty consistent p0133 code telling me it was downstream sensor on bank 1. Had to guess that bank 1 was drivers side (US) and it appears i guess right. Code has not returned yet.

 

Bank 1 is on the RH side passengers, you really should replace them in pairs. Like headlamp bulbs and b()()bs.
