Hi All,

Last month took my 07 Tribeca to replace winter tires. One of the metal caps stained so badly, and I ended up with a rim with broken valve and also useless tire air pressure sensor. I needed to buy a new sensor from Subaru dealership, so I drove with 3 sensors for 2 days until the arrival of my order for one (Tire Pressure Sensor)TPS.

Surprisingly the TPS lights did not turn on. I called my mechanic, he said that it should be flashing, or the system is totally a BS.

After 2 days he installed the new TPS and put the wheel back. Since then, the TPS light start flashing only when the speed goes over 120 Km/h.

Please if anyone can tell me how I can stop it or what i need to do to fix this.

Thanks

I'm assuming the dealership recoded all the sensors. I believe even if one is bad and replaced, you still have to recode all the sensors. We had a TPMS issue and they had to replace one. They reprogrammed all the sensors and all was well.
