Hi, I am a long-time member of the Jaaaaag community, having had my XJL 5.0 for 11 years now, but just joined this group.
I decided I needed a new car, but couldn't bring myself to part with XJL (the best car I've ever owned). So I did the only sensible thing possible and bought a 2021 F-Type R convertible.
I've been enjoying the heck out of it since i got it 2 weeks ago... but I just got the check engine light on yesterday- right before the dealer tags expired.
Anyway, I got 2 codes:
P0042- HO2S Bank 1 Sensor 3
P0096- Intake Air temperature sensor 2 Circuit Range/Performance
Is it possible that the first issue with the O2 sensor is causing the second issue? Of note, this car looked to be in good shape but was rebuilt after water damage.
Also, is Bank1 the driver side or passenger side?
Lastly, are all O2 sensors for all models the same? I am seeing some O2 threads and part numbers, but none in the '21 model.
Thanks!

my engine lights came on last year, reading indicated O2 sensor, but mechanic stated car actually had 6 total. I replaced them all, $400 total charge. Haven’t had issue since
Not a mechanic but have changed my own sensors (easy), a quick search should show the laterality of the bank, and which sensor is required. Sensor 3 is downstream. The connectors are different for each bank despite being the same sensor, so get the correct one for the side you need. The IAT fault seems unrelated but electronics are crazy so I'd do the O2 sensor first and recheck after cleaning the IAT contacts. Probably got wet though....

1. IAT and O2 sensors are not linked, IAT monitors intake system, O2 sensor monitors exhaust system. There is no way a faulty O2 sensor would impact performance of IAT sensor. You have two separate faults.
2. Bank 1 Sensor 3 is the sensor on right hand side of the vehicle (passenger side in US). Sensor 1 is 'upstream' before exhaust gas reaches CAT. Sensor 2 is in the CAT. Sensor 3 is 'downstream', post cat in the centre pipe.
3. Jaguar tried a range of O2 sensors after high failure rates with early sensors, causing expensive warranty replacement costs. You will have to search by VIN number to find the correct JLR part number. The part numbers vary based on manual/auto transmission and AWD/RWD. This is mainly due to different O2 cable lengths caused by the differing configurations. Go to > Jaguar Palm Beach parts and search for Oxygen Sensor (Rear Lower) that matches your VIN range. The left and right sensors are the same on the 5.0L models. The JLR Dealer costs are very expensive, but all the F-Type O2 sensors are actually Bosch, so once you have identified the correct JLR part number, do a Google search for the equivalent Bosch part number as this will work out much cheaper.
I've just replaced the Bank 1 Sensor 3 on my 2018 V6 Dynamic, JLR cost for T2R54607 = £217, Bosch original = £58. It's a relatively easy job as long as sensor is not seized. Easier if you have access to car lift, but can be done with rear wheels on ramps if you are slim I'd say 1 hour tops. Don't forget anti-seize compound on new sensor threads (don't let it touch sensor tip). You will need ICarsoft or Dealer to clear the MIL once new sensor fitted.

Awesome! Thanks!
Can I ask what ICarsoft is, and how I can use it?

Great comprehensive answer / response. Spot on!
Also the sensor 3 failures are typically the heater circuit.
hello everyone! I have a quick 02 sensor question
