I have a 2007 XKR. It is due for the smog check required by California. I was told by the smog check guy that it would not pass because there is a code pending. He showed it to me on his smog system. There is no code yet. Apparently one might be coming.

This link explains pending codes: https://vehiclefreak.com/difference-...codes-in-obd2/

"Pending codes are codes that have been detected but haven’t reached a certain threshold"

Has anyone experienced this? Is this a known issue with this car or Jaguars? Should I expect to see a code soon or could this take weeks or months?

What's the code Biff? Some codes require multiple run cycles to finally clear. That of course assumes the problem has been repaired or the problem repaired itself (like a one off sensor issue or something similar). If your check engine light isn't on, it should pass the smog test, but I don't know what a smog guy is or California law. Having the code would help.

 

If the MIL is not on, and P1111 is the only DTC stored, the vehicle should pass the smog check.

 

To Sean, there is no code yet. The machines they have at smog certification centers pull more OBD2 data than the code readers the average guy has in their garage. It just says that there is a code pending which normally indicates a code will be produced in the near future. You cannot pass smog if a code is pending. A "smog guy" is the technician at the smog certification center that runs the tests.

I can either wait to see if a code is eventually produced or got to a mechanic and see if they can figure out what the issue is.

Thanks. I have SDD and I think it does display pending codes, hence my confusion. I might be mistaken though, I use SDD so little anymore.

 

I have been running a p0500 speed sensor code for several months on my 2013XKR. I think I am now on threshold of getting rid of it. I do not drive the XKR that much any more, so it has been an effort to run sufficient cycles and miles to correct it. I finally bit the bullet and took it into a main dealer late last week. They have cleared all the codes and told me to burn roughly 1/2 tank of gas and that should do it. I have a fairly open schedule this week so I intend to get it done by the end of the week.

 

I don't think that is true but in any case it's irrelevant.

Sometimes.

But some cars (e.g. lots of Fords & Jaguars) always have at least one pending code (P1111 or else P1000) and by way of example P1111 is harmless (well, actually it's good because it means all the supported OBD monitors have run happily).

Rubbish. I hope no smog guy said that!!

It's very common to have pending codes e.g. as stated above.

Ignore pending codes except if you're hunting for an actual problem when they _may_ be a hint.

Bear in mind vast numbers of Fords & Jaguars have P1111 when smog tested so would never pass if your original statements were right.

Now, smog tests usually want most or all of the supported OBD monitors set. Fords & Jaguars typically show not all are by having P1000 instead of P1111, but the smog tests do not check for P1111 or P1000 - instead they test the actual OBD monitor status (a strategy which works for all OBD II cars, regardless of make).

 

No code yet? This sounds ridiculous. Try another smog station.

 

The smog technician didn't tell me that there was a pending code, he showed me the information on his smog system. It clearly said "Pending Code". I called the Bureau of Automotive Repair (BAR) and the person on the phone said that a car can pass a smog test with a pending code.

+1 on finding another smog station for the test.

 

I am not a gearhead. I have a 1996 Jaguar XJS. 5-6 years ago, I went through months of trying to get the OBD computer codes to cycle. No luck. It had no emissions issues. I took it to a rep for the State of California (can't remember name of the place) who just told me to find another mechanic. I did find someone who found a replacement computer and all was fine until this past year. My mechanic who has serviced the car for a couple of years has been only able to get one code to cycle correctly (or whatever the term is). He has had the car for 7 months.
There are no emission issues, no light on. He no longer charges me; but, has taken it as a challenge to rectify the problem. He also has taken the car to the State of California who will no give a waver. It runs great, looks great. I am about ready to park it in the garage until somebody wants to buy it, if ever. I know the State of California wants this car off the road...maybe it will really happen. Very frustrating and my wife is not happy about it!

 

Here are the drive cycle requirements and steps needed to get the emissions monitors to set so the only DTC remaining is P1111:

these don’t set P1111……

 

If the vehicle has been driven through the necessary drive cycles, and there are no set DTCs the vehicle should pass the smog check.

I have had vehicles pass with one monitor not set.

 

NBCat, Thank you for the drive cycle requirements. That information is very useful.

My car did pass the smog yesterday on the 3rd try. There was a pending code on the 2nd try but I think there was also an oxygen sensor issue where the car had not been driven enough since the battery replacement and/or code clear. I believe it was the oxygen sensor issue that prevented the car from passing the 2nd time and not the pending code, even though that is what the technician indicated.

Biff

 

That's great. Smog stations generally do the 2nd test for free if the car fails the first time. Did they also give you the 3rd try for free?

 

They charged $65 for the 1st test and $25 for the 3rd test that passed. They didn't charge for the 2nd test. I could have complained about the $25 but I was happy to just be done with it.

After clearing a CEL by replacing the EVAP pump, I was told I had to drive 300 miles for my smog test. But when we tried it still hadn't been driven enough to allow the test. At about 400 driven miles, we retried and it passed easily. Not bad for 201,000 miles.
