    Hello everyone,


    On the way home from work tonight, my 2009 Dodge Challenger SE started to display a flashing TPMS ( ! ) light. After about 70 flashes the light remains solid. See video below.





    I pulled into a gas station shut the car off and checked the PSI in all 4 tires. They were all good. When I started the car back up the TPMS ( ! ) light started blinking again then remained solid.


    It's November here in Seattle, WA and the temp drops as low as 40°. I also read the TPMS sensors usually don't last over 10 years and my car's age is 11 years. I'm bringing it to dealer to check for codes tomorrow. Anyone know if it's usually the individual TPMS sensors or TPMS module? Also, where can I find OEM TPMS sensors online?


    Thanks in advance!

    As I recall, a flashing light means system trouble, whereas a solid light means a low tire.

    The TPMS warning light will illuminate when a tire is low and should eventually go out after a tire has been inflated to its recommended pressure according to the vehicle’s door placard, according to ATEQ TPMS. After starting a vehicle, a TPMS icon will turn on for a few seconds. However, if the light stays on, it indicates that one or more of the tires on the vehicle are at least 25% below the recommended pressure.

    If the light flashes for one to two minutes, it indicates there is a malfunction in the TPMS system. There are many situations that can cause a TPMS warning light to come on or flash. In your case, it is probably dying batteries in the sensors.

    well to say that your car is now 11 years old, I would say that the sensor or one of them is probably dying. I have a 2009 also, so I would expect anything to happen. not sure what the life expectancy is on these things, but hell replace replace replace....lol
