Does anyone know if the TPMS on a 2007 car throws a wobbler if the spare wheel is removed from the car?

As part of my ongoing restoration of my L322 I want to reinstate the TPMS system on it. I know many will call me stupid but it's saved my bacon before when towing and alerted me to a gradual drop in pressure so I'd like it back.

My car has an LPG tank in place of the spare wheel so I don't want to buy 4 new sensors and find out they don't work.

Thanks,

Having another read through the manual, I've answered my own question

If the TPMS module expects the spare tire to be fitted with a tire pressure sensor and it does not, the module will not show a fault to the driver, however a fault code will be stored in the TPMS module.
