...it's not throwing a fault code. None at all. The dealer did mention that the computer module for the TPMS costs $2,100.

 

was this a fca/dodge dealership...that price for a wireless control module seems incredibly high.

 

Have you checked the owners manual? IF it has a reset button, the manual should tell you where to find it.

Also, don’t go back to that dealer. The fact that they “mentioned” the cost of the module suggests to me that if you take it back, they’re just going to tell you that’s what it needs.

 

Yes...it was my local, authorized dealer. They weren't pushing a replacement module ...just noting that it didn't make sense to spend that much on a 10 year old van with 255k kms. In fact, they liked my black tape 'fix' ..lol.
I have time this weekend, so I'm going to try a couple of things: (1) disconnect the battery for a a couple of hours, and connect the positive and negative cables together. 'Foke lore" says this will completely discharge all capacitors, etc and remove any residual power in the system. (2) ..if that doesn't work, then I'll fiddle with the tire pressures (put them up to 42 pounds and drive around for a while ...then lower them to 38, etc. I'll report back progress ...if any.

 

UPDATE UPDATE UPDATE

Okay back in action here after being sidelined with the flu for a couple of weeks.
1. with a very accurate tire pressure gauge, I set the tire pressures to the the recommended 36 psi (they were at 36 already, except for one that was at 38 psi
2. disconnected the battery for a a couple of hours, and connected the positive and negative cables together to remove any residual power in the system.
3. reconnected the battery (TPMS light came on right away). Drove about 40 miles, light stayed on.
4. I increased the tire pressures to 40 psi all around, and as soon as I turned the ignition on, the TPMS light went off. WHAT THE HELL??
I'm going to leave the pressures at 40 psi for a few days and see how it behaves, then lower them back down to 36 and see what happens.
Stay tuned ...

 

did you even read post 2?

 

Sure did. Did you not read the other posts?
-dealer re-set with scan tool ....didn't help
-and I did adjust the tire pressures .up and down ....didn't help.

 

you are adjusting the tire pressures higher now and the light went off....sheesh !

 

I followed an advice listed in the forum and over-inflated all four tires to 40 psi. I drove the car a few miles. The yellow "under-inflated tires" sign turned off.

 

The TPMS button is the reset
