Hi
I have a TPMS problem that started a few weeks ago, car is Gen 1 997
I got a ns rear low pressure warning, so I checked all 4 tyre pressures and found them to be fine.
Then I got ns front and rear warnings. Then three pressure warnings. Sometimes over inflation, sometimes under inflation.
The TPM units themselves were all new in January, and are OPC units.
So a visit to the OPC was booked for checking the sensors. All 4 show 92 months life left in them, so there isn't a failing one and a dominant one to report back the wrong reading.
The OPC reset everything, and it was back in learning mode. In about an hour it was back to square one, the OPC says to bring the car back for further investigation.
Some days there isn't a problem at all, some days it seems to go into random warning mode.
If the sensors aren't faulty, what is the module receiving the reports - is it a stand alone module or part of a main ECU?
Has anyone had any prior problems with hot weather and intermittent faults on TPMS?
