My paperwork with all the specs for the car such as black pack wheel types etc doesn’t say anything about tpms at all. When I run my icarsoft scanner when it gets to tpms it asks me to say yes or no is it fitted? Is there an easy way to find out without getting dirty?

 

A quick check, although not guaranteed, is to look at the valve stems on the wheels.
Metal - most likely TPMS
Rubber - most likely NOT TPMS

 

TPMS was mandated for all passenger vehicles in 2007.

Drop the pressure in one tire and drive a bit, see if you get a warning.

Sometimes TPMS is disabled by someone, although this would be illegal for any legitimate shop.

 

I believe the mandate did not take effect until September 1st of 2007.

Source:
DEPARTMENT OF TRANSPORTATION National Highway Traffic Safety Administration 49 CFR Parts 571 and 585 [Docket No. NHTSA 2005-20586] RIN 2127-AJ23 Federal Motor Vehicle Safety Standards; Tire Pressure Monitoring Systems; Controls and Displays

Vehicle manufacturers need not meet the standard’s requirements for the TPMS malfunction indicator and related owner’s manual language until September 1, 2007 (i.e., at the end of the phase in), and vehicles produced by final-stage manufacturers and alterers must be equipped with a compliant TPMS (including a malfunction indicator) by September 1, 2008.

I might be wrong though, . . . .

 

Since the OP has a 2013, it should have been fitted originally.

 

Yeah the OP has a 2013 and the TREAD Act applies to his car. Irrelevant though since Jaguar was already compliant with the law's "phasing in period" on all of its X150's here in the US. Once compliant with the law, a shop can't legally disable it. You as an owner are free to disable it if you want. That's still legal under federal law but some States may have stricter regs. Now you know.

 

Yes, totally agree.

I only mention the information about the date of TPMS compliance because many years ago I was at a shop where there was a less than friendly discussion between the car owner and the Service Manager about the "failed" TPMS sensors and since all failed it must be the control unit. I was a bystander. I carefully tried to point out that the XK in question might have been built before the mandate cutoff. I was rebuffed by the Service Manager and told the discussion did not include me. I was just trying to save the other owner a possible unnecessary charge, especially for diagnostics. I went back to the waiting area and waited for the tech to finish updating my car's software. I don't know what happened to the other XK because I never returned to that dealership (now out of business) and did not know the other XK owner.

My intention was not to "correct" any information directed to the writers in the thread above and only to possibly add some information that might help another owner on the Forum. I'll go back to my garage now.

 

Have we become that lazy not to check the tire pressures..

It's my wife's favorite thing to do!!!

On her ex epace they gave the actual pressures..

On he new Audi,,Bupkiss..

just a warning light that maybe 1 tire is low,,,?

 

So my valve stems appear rubber and I have been running with one front tyre lower by about 5psi so I don’t think tpms is enabled or maybe not fitted. This is a 2013 South Africa model

Stems feel like rubber

 

Correct. That is not a TPMS stem. Doesn't mean that car isn't fitted with it though. There may be receivers behind each wheel arch.

 

Your profile says your location is Los Angeles, so we thought it was a US spec car. Since the car was built for South Africa, and has rubber valve stems, and I’m assuming no TPMS warnings? The answer to plug into your scanner would be ‘not fitted’.
Given the headaches some have had, even if the rest of the hardware was pre-installed, you probably wouldn’t want to turn on the TPMS now.

 

This does not answer your question but a point of reference; oem tpms wheel sensors have metal stems however there are aftermarket sensors which use rubber stems as well as metal. The rubber ones have a lower mph rating. Discount tire installed a rubber stemmed one in a wheel I had replaced once, I called the manufacturer and was informed of the lower rating but also told that they never actually had a failure with the rubber ones.

Interesting perspective. No, it is not used as a way of checking tire pressures. Yes, it will raise the alarm that pressures are amiss while underway.
I have 3 sets of rims all fitted, no issues whatsoever.

 

I miss that on my Genesis. Gave individual tire pressure so I could notice patterns. Always the rear drivers side when it got cold.
discovered a little bend in the rim.

 

Jaguar typically shipped higher end (loaded) cars to some countries like South Africa. To @guy point, you don't have tpms valves but it could still be fitted. Pull back the fender arch as he suggest and it you really want to know. you'll see the little antenna looks like a tennis racket indicates the parts are there. But you're still missing the TPMs valves.

I turned mine off long time ago. I just use a gauge. FWIW if you really want it, @arenaej installed BT sending units and displays on his phone - has alarms too. These are internal valve stems. They work fine and that's what I would use if I were to turn it on again and only if I needed new tires because like others, I find it not worth the expense.
