TPMS reading opposite corners?

[lee gsi]

Retro fitted the TPMS to my car.

For about 3 weeks I was running around with it activated and showing readings from all 4 wheels even though I had only fitted the front receiver.

I had noticed that it was showing a rear nearside tyre with low pressure. I checked them all and it was the front offside that had the low pressure.

I put it down to it only using that 1 receiver.

Yesterday I fitted the other rear receiver and the loom but its still the same.

Has anyone else had the problem of TPMS reading opposite corners?

Can you not just swap the wheels around?

[lee gsi]

Tyres are directional and I am not sure it works like that.

I might take the rear trim off (Again lol) and leave it unplugged for a while and see if it resets itself.

[Big Sig]

Actually i think your right, its not as simple as that

Just been out and disconnected the control box so will leave it like that for a few hours (Or till tomorrow).

Took the wheel off to check for the leak and it was the TPMS valve. It was already tight and didn't want to over tighten it and break it.

Ended up loosening the nut off quite away but not fully (Didn't want it to fall inside the tyre) and carefully pushed it back and wiggled it (Loads of air was escaping) for a bit so it would reseat. Did the nut back up and inflated tyre back up to correct pressure and it looks like its ok now (Poured water on the valve and no more bubbles)

Just need to work out why its reading opposite now.

Lee have you had it Tech 2'd yet as you need to set the system to learn mode now you have the full setup. It also needs Tech 2 to set the warning limits that you want.

Not been Tech2'ed yet but the warning comes on at 29psi

Need to pin my mate down to get it Tech2'ed.

I think thats the answer Lee as the system has not been activated properly due to the receiver being missing the control unit has identified the wheel sensors but doesn't know where they actually are yet

I had same problem Lee... I also had the problem of the 'Low Pressure' warning on all 4 tyres every time I started the car... I "opcom'd" my TPMS system in but Tech2 has more options to reset and setup the TPMS ECU. Once I'd had mine Tech2'd it was perfect.

hi lee

yes the system must be tech2`d properly so the sensors learn with the
recievers correctly,although your getting readings but their not true readings
till its been programmed properly,1 of the procedures douring programming is
that you have to take the car on a drive so the sensors learn with the
recievers etc etc so dont be put off the info your getting atm cuz its not
programmed properly.


p.s i did tell you this while back it need programming properly
