Tpms not reading?

This just happened to me yesterday, added a few pounds to each tire including the spare due to the light going off due to cold weather and now after two 20 miles trips I'm still not getting any indication from any of the four tires although in my case I never get a low tire pressure warning indication, I get no indication of how much air is in the tires.

Sensors are the original OEM and although getting older I can't believe all four have failed at the same time. I can press the TPMS reset button and get the indicator to flash three times but still no readings after a few long drives.

Truck is due for a new battery so perhaps that might be related to my problem.

I'll update my post if anything changes.

 

Tpms battery life is a concern but usually you'll get a flashing light when they go dead and stop communicating.

Sometimes I've had luck reading and clearing tpms related trouble codes to get the system to wake up

Even without dead batteries the sensors can be finicky and code for no reason

 

How are you reading and clearing TPMS related codes, scan tool?

I'm not seeing anything on the dash indicating a possible code thrown but I haven't plugged in a scan tool yet.

 

Yes. I have a few scan tools at work with varying levels of capability. A basic obd2 reader won't get you into the tpms system

 

I don't have anything beyond a basic OBD2 reader.

I guess I can try pulling the battery cable and see if that will reset anything. It can't hurt.

EDIT: No change in status after pulling the battery cable and taking it for a 15 mile drive.

 

Just a follow up...

Dealership was able to manually program sensor position and the air pressure information was restored. There were no TPMS faults listed in techstream. I've also replaced the truck battery, it's the original that's almost seven years old and well past due for changeout.

My guess is I had aired up the tires with the truck off and there may have been a low battery voltage that maintains system memory. When the truck was started and new tire pressures were present the computer may have been "confused" and was unable to determine which sensor what was in which wheel. Truck never gave a low pressure indication so I figured it was getting information from the sensors but couldn't determine which was which to provide an accurate display of each.
