Hi All

My TPMS light flashes at times then goes out for a while. There are times when it stays on solid for good while then goes out. I checked the pressure: approx. 35PSI front and 40PSI Rear. I know it should be 32PSI and 42PSI front and rear respectively. But, I can't believe that those couple of pounds would make a difference.

i noticed they could be pretty fickle as well. it's actually 38/42psi for front/rear, but i agree that 35/40 shouldn't be enough to set 'em off. grasping at straws here, but how's your tire gauge? i have a cheapo one that i've found to run less accurate (reads ~3-5psi higher) at higher psis so i have to compensate.

Not that one or more can't go bad, but do you have a full size spare with TPMS that might be low on pressure? I think the light just shows on start up w that. And per above you're not using a cheapo pencil guage are you?

Btw, Hugebob I see you're from the USA. So am I!

Thanks for your responses guys. As for the gauge, I think it's a cheapo. I've got another more solid one that I think I'll try tonight. I don't think I have a full size spare. Well, it's not a tire like the Conti's. But, it's not a doughnut either. Could there be a TPMS sensor in there too? I'll check that one too. BTW, what do you think of those digital pressure gauges?

I would just invest $25 in a good USA made (if possible)mechanical dial gauge from NAPA or someplace...you can drop it, it lasts forever, they always work and never need batteries.
