The tire pressure warning light stays on continously. Tire pressure checked for P285/35 R22 tires @ 36 front and 42 rear. The tire pressure sensor alarm won't go out. Took the vehicle to a tire shop and they replaced the TPMS on all 4 tires and calibrated them. 5 minutes down the road, and the alarm came on and remained steady. Now what? Does anyone have this problem? I have 3 different vehicles and none have ever had this issue. Usually you replace the sensors and that's it. All is well. Not so with this Range Rover. I'm stumped.

sensor pick up loop behind the wheel arch liner?
I didn't know there are sensor pickups behind the wheel arch. Is there a way to discover which it may be? Front, rear, left, right?

they look like this
if it doesn't tell you which one is throwing the fault you may find it with diagnostics like GAP IID..
or you have to peel the wheel arch liners open and have a look

Doubtful.

I don't know for your car but it might be worth looking at the new stuff from Blackbox Solutions.
And of course the module that controls if is in the rear cubby holes (prone to damp) so worth looking in there too.
From my manual.
“Fault Detection
If a sensor fails, the amber warning indicator in the instrument cluster will be illuminated. A message 'XX Tyre Not Monitored' will be displayed in the message center in addition to the amber warning indicator.
• NOTE: 'XX' is the tire position on the vehicle, e.g. FL (front left), FR (front right), RL (rear left) or RR (rear right).
If more than one sensor fails or the TPMS module develops a fault, the amber warning indicator will be illuminated. A message 'Tyre Monitoring System Fault' will be displayed in the message center in addition to the amber warning indicator. This fault could also be caused if RF interference near the vehicle affects the system signal reception. When the interference has ceased, the fault will be automatically cancelled and the TPMS will operate normally.
If a tire pressure sensor battery voltage becomes low, the sensor transmits a message to the TPMS module. The module stores the low battery condition as a fault flag in its memory with no other visual warnings displayed. If the battery fails, the sensor will stop transmitting and the TPMS module will transmit a message to display 'FL Tyre Not Monitored' for example in the message center. The dealer should interrogate the TPMS module for the fault flag using a Land Rover approved diagnostic system to determine the cause of the message. If the battery has failed, the sensor must be replaced and the stored fault flags removed using a”
So you may have 2 or more duff sensors
When we switch to our winter tires which don’t have TPMS in the wheels, all we get is a fault show after 15mins that says no TPMS monitoring available, just goes away.
Not looked at our Gap in the TPMS. But will say it’s been a good tool for us so far.

Awesome response J.
So, I have replaced all 4 sensors. The tire tech reset the system with his TPMS handheld device. All errors were reset. No errors were noted. However, as soon as I hit the freeway, the alarm light came on and I received the message: "TPMS fault." I haven't received a specific tyre fault though. The Gap tool is quite expensive. I may have to spring for it.

nope. I double the pick up loops would go bad, I think you'd be worth checking the two pin connectors into them though

interesting that you got a fault only the freeway.. nothing before hand,, what kind of distance to the freeway ?
the GAP IID is expensive but you will save more than that trouble shooting and also they have a high resale value.. I've seen used ones going for 3/4 of the price I paid for mine
It also seems to mention in the manual 15mins before messages after being stationary for more than 15 mins.
Which makes some sense cos we don’t get our message until we have been moving for about that.
Was the freeway about 15 min drive.
Although the piece I posted mention sensors (assuming wheel sensors) the same fault may still be true if the loop pickups are duff too maybe.
So as Adamwest said I would look at the loops too.
Oh and water in the boot

Thanks to one & all for your assistance with my TPMS Issue. The freeway is approximately 5 minutes away from the tyre shop. I did see somewhere that I need to drive the RR @ 18MPH for 15 -20 minutes to set the TPMS sensors. This weekend, I can remove the wheel well covers and inspect the pickups including wiring and any water/debris damage.
Incidentally, My windshield got a nice crack,due to stone chips. Turns out the windshield is unique, so my insurance has to install a "dealer only" one. Sheesh!
