tire pressure sensor problem.

[synthetic-ms3]

Tonight i was meeting up with some friends of mine in a sketchy part of town and was forced to traverse through some quite uneven roads.... At one point before arriving at my destination i quickly turned down a street which had a drop-off and hit my lower end pretty hard... less than 60 seconds later i arrived and turned off my car... A few hours later while pulling away my tire pressure sensor went off randomly. All my tire pressure appears to be just fine.... did i mess up my tire pressure sensor by hitting my front end too violently???

tomorrow i plan on going to autozone and seeing if resetting the ecu will cure this problem... my car is still stock and under warranty.

did you check the spare?

why would there be a tire sensor going to my spare in the trunk?

What is the pressure readings?.. I wouldn't go to autozone for that, just add a pound or two to see if it goes off.

the lowest was 32 psi... i filled them all between 34-35 and the pressure light went off.... that's so stupid!.. i could have sworn i've have pressure below 32 and the sensor didn't go off.

Those sensors are a little goofy, they'll go off if the pressure changes, which happens a lot to me in the colder weather as I warm up the tires.

TPMS is worthless. The only reason it's on the car is because it's a requirement on all newer vehicles (past 2007 I think? I honestly don't remember the cutoff). It's more of "idiot-proofing" than a real warning system. Don't trust it, keep up with regular maintenance on your own. I check my tire pressure at LEAST once a week to make sure everything is ok.

Exactly, I was relying on it and then when I checked tire pressure, my drivers side front wheel had a nail in it and was @ 21 PSI; all with no TPMS warning. Now i check my pressure like I used to before TPMS; twice a month.

yea i work with them all day and ive had 2 days off training devoted to just those stupid things they will go off usally 3-4 pounds below and in some cars 3-4 pounds over to and dont ever use fix a flat or any tire repair sealant in them cuz then you will be buying a sensor i just put motegi mr 116 18x8 on my car and i left them off 215/45r18 potenza re-11 xl tires left them in my stock wheels for winter with blizzak lm-60 on them

This scenario happened to me, but my front passenger side. I dont know if i was poor install from the mounting place I took it, but for a week I heard clunking from that same side when driving slowly, and the TPMS light was also on. I found out it was the TPMS and it was freakin totally loose inside the tire/wheel, so took it into mazda and they were nice enough to replace it under warranty. TPMS is love/hate. Hate that light.
