4x New Wheels & TPMS. All are correct, but still error on dash.
 

I picked up a new set of wheels and bought the correct TPMS sensors for my vin and year car. Using a TPMS tool, I can read and write down every serial number of every sensor. Then using my scan tool, I can see the ECU in my jag has the proper serial number for each TPMS sensor. I have driven over 400 miles and 3 weeks, and am still getting a TPMS error on the dash. What gives? The computer sees the correct serial numbers. Why does the dash keep giving a TPMS error?

Did you activate them from ship mode?

I dont know what that is, but they are all reading accurate pressure on my TPMS tool and the jaguar ECU has learned all the serials automatically.

Often the TPMS are in ship mode so the batteries don't die and you have to activate them (with a 125 hz signal if I remember correctly), however since they are reporting pressure, this does not seem to be your issue.


Did you get the right HZ sensor for your vin? I believe roughly ~16MY and beyond used 433 hz sensors, but prior to that a different value was used.

Ha. they are indeed aftermarket. Son of a bitch

Sadly that has been an issue on many Jag vehicles. I had the same on my XF - they registered (and actually worked intermittently) but I got the error much of the time. Swapped them out for OEM ones in the end and they were perfect

Unfortunately the oem ones aren't cheap. Although note that at least on mine they are FoMoCo (Ford) so you might find a lower cost oem source depending on whether that's the same for yours. Jag has used two different frequencies so you need to make sure to get the right ones for your car

Weird. Whatever shit they slap on at tire discounters works fine.

That's because they know what they're doing. There's probably some programming trick to make them work on JLRs.

I used the TPMS from tire rack on my 2016 R - work fine and much cheaper than OEM. Details are in another thread on here somewhere.

When Discount put on Michelins they didn't change actual sender just the sensor as a free " rebuild." Has always worked just fine.

I left tire discounters with the error light on, drove around for 3 days and then it started reading them.

Well i didn't have the light at all for the first 24 hours, and then it popped up the 2nd day with all 4 showing "X". Discount tire couldn't figure it out, not that i'm surprised and said all 4 tires were reporting to their tool, albeit one took much longer than the other 3 to report.

Either way I absolutely don't believe they need to physically read a code off the sensor to program my car. I would trust the sensors should digitally broadcast their ID like every other OEM on the planet.

There is a specific re-learn process, especially when using the VDO sensors from Tire Rack. It was something like, rest 30 minutes, drive 30 minutes above 30mph, let it sit for 30 minutes. I need to go find the details (they are actually made by a US company, Branded VDO owned by Continental)

Sensor Relearn Procedure
1. Ensure all tires are inflated to the pressure listed on the tire placard.
2. Scan each sensor to verify that they are in Park mode and not Ship mode. If in Ship mode: a. Bartec: Relearn Æ Vehicle Æ Wrench (Relearn Toolkit) Æ Set Sensor to Park Mode. b. Ateq VT56: When scanned, the sensors will be placed into Park mode automatically.
3. Vehicle must be parked for at least 15 minutes.
4. Then driven for at least 15 minutes above 30mph.
5. Then parked for at least 15 minutes to complete the relearn.

I had no issue whatsoever with this procedure. Make sure that you have the correct frequency 315 vs. 433. The dealer had them wrong in the online parts catalog (correct in Topix). Pre K16000 VIN is 315Mhz.

I will try this week.
