How old are the TPMS sensors?

 

What are the actual pressure readings on the tires? The light will come on both for low pressure in one or more tires as well as too high a difference between individual tires even if they are within spec.

 

Turns out it was my radar detectors interfering with the TPSM wireless signaling. Shut off radar detectors, TPMS light goes out pretty quick. Turn radar on? TPMS light comes on. So, that is the culprit.

 

Turn off your cell phone chargers. It turned out to be my radar detector interfering with TPMS signal on my Sedona. However, wireless chargers, cell phones and other plug in chargers for the car can interfere with TPMS signal. It is possible you have a sensor that is at end of life with its battery too.

 

My wife reported this evening her heated seat got hot today with no indication or buttons pressed. She is wondering if her car charger might be the culprit. I know it kicks the tpms when I phone is connected. Are the two close to each other in the wiring or body control module?

Where is the bcm on these?


Thanks

 

I'd unplug the heater potentiometer. It may be shorted out and heating intermittently. If you disconnect the control pot, and it stops the issue, its the pot in the dash.

 

Is there a pot for the heated seats? They have switches.

 

My 2008 EX 2nd generation that has an adjustment pot on the center consol for each seat.I guess you have a newer Sedona, 3rd gen?

 

Is 2012 3rd gen?

 

You shoud be the same as 2nd gen. 2015 is when 3rd gen started. What do your seat heat controls look like? Is in flat screen or actual pots on the dash with 1-5 range on them?

 

Trying to post a pic.

Ok, i see. Mine is the same but has roller potentiometers to adjust heat intensity.Your's is just an ON OFF scenario. Still, I would suspect that switch assembly is flaky and replace it.

 

Had to fight the page to upload the pic.but that's what the controls look like.
