I have gotten an error that my front two tires are not being monitored any more, along with a general tire pressure system fault. This popped up while driving last night, cleared when I started driving today, and then popped back up after I was driving for a while today.

1) any danger here? Tires seem properly inflated, but I will double check
2) should I take this to my Indy shop, or the tire store (discount tire) that put new rubber on the can last year
3) any general.ideas about what might be going on?

Apologies for not thoroughly searching the forum, but I am mobile and hoping I can just get a simple answer!

Thanks so much in advance for the help!

 

1. unlikely
2. neither
3. dead/dying sensor batteries

without better info -- no fault of your own -- that's how i would approach it. overreaction costs money needlessly. replace all four sensors at the tire shop, when convenient.

 

Discount Tire charges $60 for a new sensor in my area when buying new tires. Since you bought new tires from them last year, you should try to persuade them to not charge you for labor to R&R all 4 tires and replace the sensors. I trust Discount Tire to sell new stock TPMS sensors because of their volume of business. Beware of cheap TPMS sensors sold online because they've probably sat on the shelf for years and won't last long. That's why they're cheap.

Your 2011 XK probably has the original TPMS sensors. They have an expected life of 7 years because the batteries are not replaceable. So it's time to replace them.

Note that no programming is required for the new TPMS sensors. Just drive for around 10 minutes and they'll be recognized.

 

Excuse me going slightly off topic, but XK(R)'s have a tire pressure monitor system? Which years?

I ask because my XK got a flat tire more than once, and I never got a warning about it.

Thank you.

 

All years of the X150, however not all markets required it, so a car intended for such a market probably doesn’t have it.

 

@Roarer , go to the topix website, there is no cost, and get the Vehicle summary using your VIN. This summary will lay out all the build options on your car, including TPMS. (Tire Pressure Monitoring System).

 

oops…. it seems I replied in the wrong thread. Sorry.
@Roarer , do go to topix and provide your VIN, Topix will provide a build summary sheet for your car. Then you will know if you have TPMS.

 

Thank you all!

Sorry for the delay in getting back, I have been slammed. But this information is exactly what I needed!

As a note, the error keeps coming in and out. Sometimes it is an issue, other times it clears itself. Monday I will go to DT and get new sensors!

 

Topix no longer provides the.build sheet.

 

You can get build details from your VIN. Click on this link, enter your VIN, and press DECODE. After the report opens click the EQUIPMENT tab.

P.S. Note that the EQUIPMENT tab might not be accurate. For example, it shows that my car came with a spare tire, which is incorrect. It also didn't show that it has Alcon brakes.

 

You’re right about that, Stuart.
For my car, that decoder does not specify TPMS but does state Aluminum trim. I have the burl wood trim.

 

You can't trust everything you read on the internet.

 

Well.......

I had the sensors replaced today. $250 by the way.

The error is still there. Tire light is in, center dash says tyre pressure system fault
Any thoughts about next steps? I haven't seen the other warring saying there is a tire not being monitored.

Would love any thoughts!

 

Read all the TPMS posts in here. All of them. Could be a bare wire behind the right headlight, could be a bad initiator, receiver or module. OR, could be you just need to drive farther.

 

+1 on driving more, but also try this:
1. Underinflate all 4 tires to 25 lbs so the TPMS warning illuminates. No need to drive around.
2. Overinflate all 4 tires to 40 lbs. The TPMS warning should turn off. Drive around for a day or two - the warning light should stay off - and then reduce the tire pressures in accordance with the door jamb sticker.

Hopefully, that'll work and you won't have to investigate further. Good luck!
