Koup with 1000 miles, I searched but never found my exact issue so perhaps someone can give me a clue.

5-6 times in the last two weeks after about 1 hour of driving I have had the ((!)) low pressure symbol flash for about 1 min, then go solid and go out or go out upon restarting the car. I have checked the pressure cold and it was 32 psi on the dot. Thinking it was getting too high (don't know the upper limit) I dropped the pressure to 30 cold but still had the issue recur.

Last night the light flashed and went solid a mile from home so when I pulled in, I checked the pressure hot and all were 32-33 psi so it's not an overinflation issue AFAIK.

I have read it can be caused by RF interferance but really it's wierd that it's happening after about 45-50 mins of my commute, not in a specific spot.

I reinflated to 32 psi cold today since I don't think it's pressure related.

Anyone have a good clue? The TPMS light has never come on.

I don't have the manual with me at the moment since I'm at work, but I think I recall reading in the manual there are certain circumstances as to when you could disregard the warnings. Check the manual under the sensors it should give you at least an idea of what they expected from the sensors. Can't offer any advice on why that is though.

My light has gone on a couple times, more so when I first got the car, and haven't seen it in a couple months. As long as it's not within the guidelines in the manual, it shouldn't be a problem. :]

Wasn't there some weird issue with the TPMS and the gas cap being loose causing the warning light to come on? I don't have the SX so haven't run into any TPMS issues.

My old EX sedan had TPMS also..?
