The history: I was ham fisted removing and replacing my thermostat and broke a 1/8" diameter PLASTIC vacuum hose that goes to the SAI vacuum reservior. This resulted in me having a SAI monitor (AIR) flashing on my diagnostic scanner.

So I found this vacuum line and repaired it.

The question I have, is: how long will it take for the secondary air monitor on my scanner to go away? I've done a PCM long and short drive cycle (see secton 303-14B of the workshop manual) and that did not clear the monitor from flashing on my scanner, yet.

I'm not too surprised that it has not gone south yet. I've read about DTC 0440 and how long it takes to be removed on a 2000 Chevy after repairs have been made (something like 40 startups showing no problem, if memory serves with the ECT and IAT temps being within a certain peramenter).

Just in case: I know this is not a P0440. But I'm hoping there is a Jag mechanic that can give me a clue under what conditions will this flashing Air monitor go away? How many driving cycles or the like?????????

Thank you. And when and if I'm given a clue, I'll tell you another story that might be of help to someone in the future. Concerns "diagnostic scanners".

EDIT: So I did a search online for a P0410 and came up with what is shown in the jpg attached. Seems the number 40 is the number of starts I need to do under the proper conditions. The proper conditoins most likely require the ECT to be well below where I'd want it to be. If the ECT has to be like 86*F or less each start..........then I'm doomed for a long time for it to clear. This is Tx and while we've had mild weather that last week, in the next few days it's back to the mid 90's and 100 plus degrees. Not a good working enviroment to clear the 'AIR" monitor from my scanner.

No, there is no ENGINE lite on display, but if a emissions mechanic connects up to my car he will see the 'AIR' monitor has not fully reset and not give me a sticker for the windshield. Then I'll be doomed to drive a 2000 Chevy van or SL550, one or the other til it clears.

 

Well, I seem to have found the short term answer to my above question. So now I'll tell you about my OTHER adventure with my scanner.

I had this scanner connected to the Jag just for grins and to monitor my ECT temperature. No codes etc were showing. No 'monitors' flashing showing that they have not completed their drive cycle.

So while sititing there in the driveway looking at the scanner........the car went haywire. BIG triangle flashing on the display saying my transmission was corrupt followed by another triangle telling me my ECU was in a world of hurt. Plus other caution lights on the display that I swear I've never seen before. EEEEEK!

I shut the car down. Pondered. Tried to start the car. Would not start or make a sound anywhere. Pulled the scanner off the port and started the car. Still had big triangles showing my ECU and transmission where corrupt etc and other yellow caution lights. Drove the car around the block. Shut it down still with the triangles/caution lights mentioned above.

Hmmm. Scanner must have blown up the ECU and other monitors says I. Hmmmm. I put the scanner on that old 2000 Chevy van. Van would not start or make a noise etc. Hmmmm. Removed the scanner. Started said Chevy. Worked just fine.

More hmmmm. I realized the scanner had not been showing any display when connected to the van. Time to eat and go sulk a while. While sulking I had what should have been an obvious idea earlier. I checked the scanner batterys. Weak as a kitten. Put new batterys in. Started the van with the scanner connected. All was well.

Went to the Jag and started it up with the scanner. Had a U0001 or such displayed. Now here is where I got loose minded. I disconnected the scanner and went and removed the car battery cable for a minute or so, then connected it back up. Started the car. No engine fault showing on the dash. Car ran just fine and dandy.

Put the scanner on it. It now showed all the monitors were in a state of NOT READY. No codes showing. This, in my mind, told me all I needed to do was do a drive cycle to clear the NOT READY monitors showing on the scanner. So I went for a drive in the country for about 75 miles, varying my speed and stopping and starting the car serveral times.

When I got back home all but two of the monitors were in the NOT READY start. One was the 'AIR' and the other was 'EVAP'. I more or less knew the EVAP would go south in a godawful forty cycles in the right conditions, but the AIR was and is still to some extent a unknown as to the number of cycles I need to start the car and the air and water temp conditions. Seems I've a long haul in front of me.

Lesson learned: Make sure your scanner batterys are in good shape when it's connected to your car 'cause if they go bad..........your CAN network will go haywire and cause you problems. Oh.....the car runs just fine right now. Seems Time will cure all.

 

Joy to the world. I've been doing Short Drive Cycles a number of times this day and I had done one just prior to entering this post. So after my last post I went out to the car (has a floor fan pointed to the engine to cool it down), and I put the scanner on it to see how low the water temp might be so I could do another Short Drive Cycle on it.

Well lo and behold. Only ONE monitor is flashing and that is the EVAP which I know will go south in a day or so. The AIR is not flashing anymore.

Time to go get my emisisons sticker tomorrow. Your allowed ONE unset monitor in Tx and you still pass. And I know the EVAP is not a real problem and will go away in a few days.

My ranting is over. Just beware that if your using a scanner, make sure the batterys are up to snuff. If they die while your hooked up to the cars port, the loss of the scanners guts will also open up circuits in the cars CAN network and " you'll be sorry".

 

We bought our son a 2005 VDP about a year ago. The battery was replaced and it took almost a month of driving it to get the EVAP system to become "ready". We could not get it inspected until this occurred.

Have not had to "reset" anything with my car. I sure hope the EVAP systems have been improved on these later Jags.

 

I added three jpgs to this post just for FYI. The FYI is that it is going to be a long time before the Evap Emissions monitor is in the Ready state. Mostly because the criteria for this test done by the ECU, is dependent on the IAT and the ECT temperatures being under 86*F.

This is Texas and it's summer time and I'd be lucky if the temp gets under 86* in the early morning. Any time the air or water temps are over 86*F, the test won't be done by the ECU so just starting the car 40 times in itself isn't going to cut it.

That said, one of the attached jpgs shows criteria for passing the emissons tests in Texas, and it clearly states my 2007 MAY have one monitor in the unready state.

Just FYI and nothing more or less. Not asking questions this time around.

 

Update: Drove the car early this morning. After the drive all the pending monitors had cleared. Got the emissioins/safety inspection at 11am this morning. Good for another year.

Evidently it does Not take 40 cold engine starts with the IAT/ECT temperatures lower than 86*F to clear a evaporative emissions pending monitor on a '07 XK Jaguar. So much for the validity of my searches for how to clear a Evap Emissions monitor using the world wide net.

 

Hailers, if you are planning to sell your SL 550, let me know, I may be interested. Good luck on the reset.

 

How many drive cycles do you recall, it taking to get your secondary air system into ready mode?

I have a 2008 XK with 32,000 miles on it. The rear bumper was tapped on the freeway and needed to be repainted. The body shop cleared all soft and hard codes before releasing the car to me. Unfortunately, I needed to have an emissions test performed the next day and my registration was expiring in 8 days.

Went to have test performed and most of the monitors were not in ready mode. I was told to just keep driving it my Jag dealer and smog shop. Two weeks later, my tags are expired and my secondary air monitor is still not in ready mode for the test.

I have driven it nearly nearly every day and stop at the smog shop every other day to have them hook up to it and see if the system is ready yet. Still not ready as of two days ago. Very frustrating. But your post is the first I’ve heard of the number of drive cycles possibly needed versus the number of miles to be driven. Jaguar told me to drive 1000 miles.

Well, I work from home. I average about about 3,000 miles a year on my car. So, driving a 1000 miles within a few days was not and still isn’t realistic. I’ve managed to drive it 300 miles in the last two weeks and that took a lot of effort.

Looking forward to to hearing back from you
thx

 

Took mine 140 miles to get the O2 sensors to Ready, and the EVAP is still not there at 208 miles... BUT in Utah a car can have ONE not-ready and still pass emissions.

 

I'm surprised you guys even have an SAI system. I thought that was only for Euro and Asian markets.

 

Well, this IS a six-year-old thread...

 

California has strict emissions laws and rules. But not quite as strict the EU

 

Scott, I'm down the road from you in Canyon Lake, and I can't get my 2007 XK to complete the Secondary Air monitor. I presume that, by now, you've gotten yours cleared. Do you recall how you did it?

Thanks,
Doug

 

Hi Doug. I and my XK are now on Sao Miguel island (Azores).
But yes, I managed to get it to reset and communicate when the suggested 1000 mile drive didn’t do the trick.

In order for the second air system to even engage at startup, the outside air needs to be COLD.

Try to pick the chilliest part of the night, despite your current heat wave, a start your XK. Immediately drive it around the block.

This should reset it for your emissions test.

I had a body shop in Riverside repair and paint my front bumper, after I removed my plate as I prepared for my move.

I tags were due along with an emissions test that same month, which had to be current before I could import my XK into Portugal.

Hamblin body and paint cleared my computer after painting my bumper and never ask permission or even told me. To my surprise, I didn’t pass my emissions test the day after I picked up my car. I was furious when I went back to them and learned what they did. They just shrugged their shoulders and had the attitude of So Sad To Bad. Yet they were and authorized Jaguar body shop.

A year and $1000.00 later the clear coat is flaking on my bumper. I called the owner about the warranty. Same attitude again. Beware of this place.

Anyways, I hope this helps you reset your secondary air pump system so you can pass your emissions test.

 

That a wonderful opening line. Being in the Azores is unusual enough ........ taking your XK too is extraordinary!



I imagine Jaguar specialists are also a rarity there.

LOL. Unfortunately, only mainland Portugal has Jag dealers and specialized mechanics. There are a couple of late model Jag suv’s here, that I’ve seen. But my XK is the only one on Sao Miguel. It’s quite the celebrity here, when I’m driving it about. I’ve never seen so much rubber necking ever!!!! The locals aren’t shy about taking pictures of it either. But I figure My Precious is deserving of the attention.

I formed a relationship with the Mercedes dealer, here, for normal servicing like oil changes. Hopefully if anything serious becomes an issue, they can handle it.

Frankly they can’t be much worse than Jaguar of Anaheim Hills. I had my XK there twice and the mechanical expertise of my XK was rather limited. Quite a disappointment for being a main Jaguar dealership. They had no idea how to resolve my secondary air pump issue for starters. Which is why I resolved it myself after they sent my car home with unsuccessful attempts to resolve the issue.

 

Well, my friend from a distant land, I wish this forum software would let me LOVE your post, because LIKING it isn't nearly enough. THANK YOU!!! Our multi-month heat spell finally cracked, and I noticed it was going to be 54 degrees at 6:00 AM this morning. Taking your suggestion, I set my alarm clock, fired up the beast, let it idle for three minutes, and then took it for a drive. After a few blocks, I had connected the OBD interface, and OH MY GOSH -- ALL GREEN!!!

Really, thank you so much. I hope that you have a wonderful season of life, driving your XK around that gorgeous island!

 

That’s wonderful news about your car. Congrats. Always happy to help a fellow Jag lover. Too bad this little secret seems to be a secret, even with the dealerships and Jag corporate.

I had everyone involved to try and resolve this issue before my baby boarded the ship for a multi month trip.

Had anyone knew this rather obvious factor, regarding surrounding air temperature, I’d probably have less grey hair!!! Thank goodness I stumbled across the answer by process of thinking it out logistically. LOL

Best of luck with your beast. 😁
