OK, first of all, if this is a repost, blame my poor search technique.

After about 15 minutes of driving, the TPMS light in my '04 RX8 begins flashing at about a 2 second cycle - 1 on the 1 off.

I know the sensors work due to recent cold mornings. Any ideas what is going on with my Rex?

Thanks in advance,

I would start by checking the air pressure on all tires, then follow this DIY https://www.rx8club.com/series-i-do-yourself-forum-73/diy-tire-valve-cap-replacement-28064/, problem solved

 

Khronus79,

Thank you for the reply. However,since I have had this issue, I have maintained the pressure at 32psi, and since the pressure is staying at 32psi, I don't think replacing the valve caps will fix the problem.

I am concerned about the batteries in the sensors or a short in the system, and I am looking for somediagnostic help on these issues. I did read a post about some interference from an audio link system, but I don'tknow if my ReX has one since I bought it pre owned.

Any thoughts?

Thanks,

If you are REALLY at 32 PSI, then most likely you may have a battery getting low in one of the TPMS's. Think you're gonna have to get a new one!

or

find someone selling some in the for sale section

or

get a piece of black electrical tape and cover up the light.
