Don, ty, yes i did read your useful suggestion. im not sure what mode 6 tests are, so dont know if it applies.
there were a few blanked out items on the torque pro such as TID 6, but the only one with fail was TID 0$aC11 sensor period as attached Max 33423 current 65535.

i reset the thing again just in case that may help. Driving miles in this beautiful weather hood down is no hardhsip !

 

Your screenshot in post #40 shows Mode $06 data - that's what I was talking about. Somewhere in the forum I have posted a document that contains some Jaguar Mode $06 TID and CID definitions. If I get time later tonight I'll try to repost it here.

Cheers,

Don

 

Attached is the only Jaguar DTC Summaries manual I have found that includes some Mode $06 data (pages 12 and 13). In another thread, JagV8 reported that some Mode $06 data were available on the Jaguar TOPix website, but as of my most recent search it appears one must pay for a subscription in order to access any such data.

Cheers,

Don

 

But which Monitor(s) is/are unset?

Ignore mode 6 for now. We have next to no info on it or even if the data from torque is meaningful.

 

Generally the problem seems often to be EVAP related and specifically the purge valve.

About the only info I have for mode 6 TID $0A is that it is about EVAP and a leak, which would fit with the above and the TSBs posted by Bob (post #24).

For TID $22 I think it's EGR or possibly fuel tank pressure (e.g. checking pressure does not leak - this will be partial vacuum that ought to hold as a partial vacuum I believe).

Another meaning (Ford) for $22 can be to do with bank 2 catalyst efficiency. As Ford owned jag at the time it may be that.

 

Jagv8, ty for responding.
its the TID $0a showing max 33423, current 65535.
ive no info on TID 6, & in fact its blank on torque pro, so maybe its just incompatible.

i hear your point that it may be evap, & purge valve, i could try that but frankly could be anything? There doesnt seem to be freely available info fro jag on what $0a means, which is shame. I did read on some esoteric site that a lazy sensor could be to blame, i asked local mechanic who said thats just not possible, though to a layman it sounds very plausible - if i only knew how to replace that particular sensor?!

V fortunately no engine light, & after last bout of stunning driving, i managed not to show any monitor so i got my car inspection , but a few miles later, $0a showed up again. So i have a year to sort this out!

perhaps i should trade for an aston martin or bentley !! TY folks.

 

Hi Charles,

According to page 12 of the Jaguar document I uploaded back in post #43, TID $0a indicates:

EGR system flow malfunction (GA changing rate high)

It might be worth checking your EGR valve for any obvious problems (corrosion or oil on the electrical connector, carbon buildup, etc.), as well as the EGR pipe (cracks, loose flanges, leaking gaskets).

Cheers,

Don

 

D'oh! Missed that.

BTW there's a newer (2008) version that's 152pp but is too big to upload.

 

Charles -
If I understand correctly, we both seem to have the identical problem according to Torque. I did go ahead and replace the purge valve, but it made no difference in terms of solving the problem we are both dealing with.

I don't know where the evap or EGR is, so don't know how or what to do to check them. Does anyone have some specific suggestions? Don, where is the EGR and how do I get to it?

JagV8 suggests it could have to do with catalyst efficiency, which is where i am going next by replacing the aftermarket Cats currently on the car with some used Jaguar OEM Cats that I have acquired. I hope to have them on in a few days and will report back.

 

Looking at the PDF it looks to be EGR-related.

 

smtguy i have standard catalysts, so any fault is not because yours are aftermarket. If i were betting id saying thats not the issue.

i didn't do the purge valve, i did read post 2003 models had some issue post wiring harness reconfigurations which required a purge valve change. Since you did that im betting thats not our shared problem.

EGR system flow sounds plausible if its in the good book.
Cant it be a sensor issue? or am i sounding like the novice i really am.

 

The 153pp DTC Summaries Guide can be downloaded from the link below, but as far as I've been able to tell, it doesn't contain any Mode $06 data:

Jaguar X350 DTC Summaries Guide

Cheers,

Don

 

That's a very different one (and years earlier too).

I really did mean 152pp and 2008...

 

Does the manual you are referencing contain any Mode $06 data? If you can post the title of the document and Jaguar publication number, perhaps we can find it available for download online?

 

It's essentially the same as the 113pp one you posted but 39 pages bigger and consequently has mode 6 data. (Same titles, sub-titles etc. I see no actual doc ref). April 2008.

 

jag v8 is there any link to this expanded version, i tried googling without success.
TY.

 

I presume you have done a battery reset, not just a obd reset. I had P1000 for two weeks, 3 tanks of gas. I did a battery disconnect/reset, and got the P1111 all clear in the next 70 miles, 2 drive cycles.
just suggesting.

 

No idea where it may be but it's not going to help more than the one posted with this problem.

I suspect I got it some years ago from TOPIx when I had a subscription but as I say it's not got more about this problem - which looks to be an EGR one.

It's entirely possible the PCM wants to put the EGR in some known state to run cat monitor but can't get it there so can't run the monitor.

It's very hard for it to flag codes in some situations (commonly any time required monitors haven't run OK) and this may be one.

 

Well Gentlemen, I have the stock Cats back on my car, and I still get TID: $0aCID:$11. I seems like this is a permanent code? At this point I have read everything I can get my hands on, done numerous drive cycles, and I just cannot get it to P1111.

Charles, have you had better luck?

 

Scott and Charles,

Since I had the same Mode $06 codes and my problem was a small air leak in the intake plumbing, I would strongly suggest that you have your intake and EVAP systems tested by a shop with specialized equipment to find small leaks. This includes smoke machines using UV dye, flow meters, manometers, CO2 pressurization and detection systems, etc.

As I mentioned earlier, you can build your own smoke machine for less than $20, which can help locate leaks as small as 0.030 of an inch or so. See YouTube for various DIY smoke machine designs.

Cheers,

Don
