Good day everyone,
I have the above fault codes logged onto my diagnostic tool for a Land Rover Discovery 5. I have done a vacuum leak, no leaks, an exhaust leak test, no leaks. Check the PCV valve for a tear in its diaphragm, no tears.
Prior to deciding on changing the O2 sensors, I would like to know if anyone can share the Ohm measured values of the O2 sensors to compare them with the O2 sensors of the current vehicle.
If any of you have already experienced the fault codes and found a solution, please share your experience and how you resolved the above fault codes.
Thank you

 

hello did you find a solution to this? having the same issue

 

Just got the P2187/2189 lean condition at idle in cylinder banks based on the code reader from my auto parts store. I have an extended warranty but debating between waiting a week or two before the next appointment or to take it to my indy shop sooner.. Does the dealer have a more detailed diagnostic readout or will they have to troubleshoot the same as anyone else?
Sounds like PCV turns out to be the culprit in many of these cases.

 

What year and how many miles? If you're in the US many emissions issues fall under the mandatory federal 80,000 mile emissions warranty. I had my DPF/SCR replaced on my TD6 under that warranty at 79,600 miles at zero cost to me.

 

Mine is a 2018 V6 gas at 95K miles. I'm in the US but i still have some time left on my extended warranty. Will take it in soon and report back

 

Update: Got the diagnosis for the error codes from the dealer and it's the PCV valve leaking. Unfortunately, he also advised my extended Platinum warranty doesn't cover emissions so they're declining the repair, which he quoted $769 if i were to pay for it. I see the PCV service kit I can buy for around $40.. but still need to see if it's easily accessible as a DIY. Thinking it might be cheaper for me to pay the $220 diagnostic fee and take the car back and fix myself! Would have just taken to my indy shop had i known the warranty wouldn't cover and gotten it fixed in a day rather than the week it sat at the dealer waiting to be seen! Lesson learned.

 

Just got the P2187 & P2189 codes. Did you end up replacing the PCV valve yourself? How easy or accessible was it?

 

Isn't there a long terrm emmisions related warranty in a little booklet? Maybe 10 years? Required by law?
Is PCV a Positive Crankcase Ventilation valve (do we still have those on modern engines?).
Or is PCV a Fuel Rail Pressure Control Valve (which wouldn't be an emmisions item I think)?

 

Federal emissions warranty is 8 YR/80k. I'm at 145K

Troubleshot/cleaned/eliminated the fuel system, injectors, 02 sensor, MAF, etc.
After some online research, I suspect a tear in the rubber diaphragm inside the the Positive Crankcase Ventilation Valve. It is in an awkward spot on the back of the passenger side valve cover under a hose. The PCV is listed in the workshop manual 303-08 but no LR part number for just the PCV assembly (cap, diaphragm & tension spring) and zero LR documentation on ordering/servicing just the PCV valve. Dealers want to remove valve cover and replace the Part Load Breather components which seems like overkill ($800+).

The plastic tabs on the cap are susceptible to breaking when attempting to remove, so I've found and ordered a replacement part ($20). When it arrives I'll confirm fitment and attempt the procedure this weekend.
