Looking for help. I have 2016 R Type 22k miles, the engine light came on a few times then went off now on full time. I had it diagnosed and the result was P0420 catalyst system efficiency below threshold (bank 1). I have been told likely an oxygen sensor. I understand there are 6 sensors. A few questions, 1.looking towards the car from the front (RHD)where are the sensors located in relation to the part no's 2. On the diagnosis any idea which one is faulty 3. How hard are they to replace with a trolley jack ! The part no's I have looked up are front sensors C2D24756, centre right C2D54165 centre left C2D55089 rear right T2R10753 rear left T2R7732 any idea if I am right. Anybodys help would be appreciated.

 

That code is likely due to a bad sensor, but could also be a bad cat. You’d need an oscilloscope to check the waveforms on the sensors to know for certain. p0420 indicates bank 1.

 

Also, It's a good habit to get into when referencing right or left, it is always as you're sitting in the driver's seat, not in front of the car looking at it. Same as LHD & RHD. Helps to prevent any confusion when talking left side vs right side.

 

Yeah, it's also confusing when people talk about driver's and passenger's side - we have to do some research into geography to clarify!

 

I believe bank 1 is right side of car (looking forward). Since the OP's car is RHD, that would put it on the driver's side.

 

Passenger side (right side) of the car. It could be a bad cat. Hopefully just the second or third 02 sensor away from the motor. Got the code after driving hard and Dyno pulls with tune and pulley. Bought velocityAP downpipes... Problem solved! Lol

 

I don't know about the V6, but with the V8, these motors just kill O2 sensors. I believe i've replaced 4 total under warranty, and now I have the same fault again. Seem like you replace one, and about 5k miles later another one is ready to be swapped. Now that my standard warranty expired, I'm gonna call and see if this is covered under the extended emissions warranty, but i'm not holding my breath.

 

I had 2 replaced on my V6S.

 

Maybe try putting a bottle of Oxicat in the fuel tank every six months or so.
I've being doing this for years on my XFS, XFR and F-Type and I have never once had a single O2 sensor (or cat converter) problem, never mind needing a replacement.
See here for example: https://www.ebay.com/itm/OXICAT-Oxyg...0AAOSwdnNdniVR

 

While I will say I've never heard of this stuff; that doesn't mean I won't try it out. However, my main complaint, is that as I've never heard of it before, I've obviously never needed it or known anyone who has ever needed it to prevent replacing sensors ever 5k miles.

 

There is an issue with a small gasket leak on some years where a small amount of oil seeps enough to work it’s way to the sensor and ruin it. It happened on mine and it was replaced under warranty along with the faulty gasket.

 

I came across it years ago on one of the Pommy Jag forums I frequent and they raved about how good it is and that it is not just snake oil.
Mainly diesel owners (I had a diesel Jag back then) which are known for clogging up the cats and O2 sensors with carbon deposits, so maybe it's not as effective on petrol/gas cars.
My rationale is it can't do any harm and there is a good chance it does enough good to keep my cats and O2 sensors healthy so they never crap out and it doesn't cost a helluva lot, unlike the O2 sensors and especially the cats which cost a bomb.

 

Cataclean is a similar product that, at least through my research, is a bit higher rated. In addition to BG products, I bought it for all my cars. I also started running Liqui Moly in most car (except the F-Type), its supposed to be pretty good. I don't know that any of the products will make cars run forever, but I feel like keeping the oil, fuel, air, and exhaust systems clean helps performance and decreases build up which will lead to less repairs in the long run. I dont drive a million miles, so I only require one oil change each year with BG EPR and MOA (except the Jeep which gets a few more miles), and add Cataclean - BG44k goes in about about every 9 months.

 

hi unhingd.

i have a 2015 f type with a p0030 fault (sensor1 bank1) checked an oscilloscope and indeed it was indeed showing wierd graphs (attached). My performance and idle were affected as well. However, i looked for the 2015 f type R part number and it showed only C2D39892 for the front o2 sensor. Looked for 2016 f type r parts and found both C2D39892 and C2D24756 as the same front oxygen sensor. Are they interchangable? Meaning i have a 2015 but i was only to be able to find a pair of C2D24756, which is cheapertoo.

another question out of topic. I have upgraded to pierberg’s cwa100-3 sc coolant pump and got a p023b fault, which is for the sc coolant pump pressure. Is that normal. Given that my data logs show that the SC pump is on (1 value) and my charged air temps look good

 

Consider asking the dealer to cover it under the extended O2 warranty they released?
See the two attached documents for further info. Note I replaced an O2 sensor on my 2014 XJR prior to Jaguar extending the warranty. I sent in my receipt but nothing was ever received from Jaguar?

I have a vap tune and 200cell cats on my car. I’m certain they’re gonna blame it on it and not cover me lol

 

Hey guys,
FYI, Jaguar replaced my O2 sensor free of charge on the F-Type R. They are prone to fail and are now covered under warranty for a 10 year period I beleive. I have VelocityAP downpipes and they disregarded that.

 

The oxygen sensors are covered by JLR for 15 years in Canada.
