Cahvah Posted December 16, 2016 Share Posted December 16, 2016 Hi, I got my 2009 Forester in April. Since I got it I have had problems with low tire pressure on 2 tires. My local mechanic replaced the valves and sensors, and within 40 miles the indicator light started flashing for 30 seconds then going off, On the way back to the mechanic it flashed for 30 seconds and stayed on. He recalibrated everything, rode it for 10 minutes, and said the computer was recognizing the sensors. On my way home it started flashing and stayed on again. Every time I start it up now it flashes and stays on or just stays on. I live in north/central Mass, and the temperature has turned very cold. Is the temperature the problem? Any advice will be appreciated. Thanks! Quote Link to comment Share on other sites More sharing options...
golucky66 Posted December 16, 2016 Share Posted December 16, 2016 When you being it to the shop with the light on, he can pull DTCs from the TPMS module. In which case that would inform him as to why the light keeps coming on. Rarely the module is actually bad, but it is a possibility. Quote Link to comment Share on other sites More sharing options...

It sounds like I might have to bring it to a dealership. Quote Link to comment Share on other sites More sharing options...
golucky66 Posted December 17, 2016 Share Posted December 17, 2016 It's not a "dealership" thing. Any shop that actually spends the money to keep up to date TPMS tools can investigate the light. Though I'd imagine the dealership should be able to. Before you spend the money bringing the car to the shop, get a tire pressure gauge and set your tire pressures according to the sticker in your drivers door. This way YOU can verify the light isnt coming on due to low pressure (which is very possible in these 10 degrees or less nights. Quote Link to comment Share on other sites More sharing options...

II've been checking tire pressure regularly with the problem I've had, and will check again. Quote Link to comment Share on other sites More sharing options...
