TPMS System Fault

2012 Acuta TSX Wagon. ~60,000 miles. I have been intermittently, over the last 2 years, getting the TPMS System Fault message on my dashboard. The system works fine either for a week or a few days or even a few months.

Recently it has been popping up almost every time I drive the car and usually within the first 20-30 minutes. It will stay up for the rest of the drive
The sensors are original build sensors.

When the message pops up I do not see any pressures for any of the 4 tires.
When it does not pop I get all 4 pressures and they are correct.

Just now I started the car and the message popped up, but before I could get to the "tire pressure readout".. the message went away and when I did get to the tire pressure readout all was normal.

I am thinking is may be the receiver. They are available. New OEM is Over $300!!! eBay used is under $100.

Thoughts / Insights?
Where is the receiver located?
Where are the initiators located?

Thanks

/Greg

I now know where the receiver and initiators are located.

Just wondering if I should go for the receiver 1st.

If
A) One TPMS sensor, and/or
B) One initiator, and/or
C) The wiring between one initiator and the receiver goes bad

Does the entire system shut down or do you just get no reading from the bad senor / Initiator wheel?

Since the entire system goes down... is it safe to assume that their is something wrong with the main receiver under the dash?

Thanks

Greg

Yes, I believe the receiver is in each wheel well.

Did you try reading your OBD2 port for any error codes? AutoZone can loan you one if you don't have one yourself. I've also read elsewhere you can try to "reset" the system by disconnecting the battery for x minutes (don't know how long). The down-side is that everything will be erased including your radio stations, radio lock code, maybe your auto window up/down, and maybe your driving habits stored in the ECU.

ACTUALLY.. This AM it faulted out again... I remembered that there was a "menu" item called "Messages" I went there on the NAV screen and saw another menu choice called "Diagnostic Messages".. Selected that and got this on the screen
I guess I had NO ides. This is the only car I have ever owned that would present the driver with the actual DTC codes without using a reader....

" 1 ! Tire Pressure Monitor: 36"
"2 ! Tire Pressure Monitor: 38"

I looked them up on Alldata pro and found that the system was not receiving data from the left and right rear TPMS sensors....

DTC 32, 34, 36, 38:

Tire Pressure Sensor Signal Failure

NOTE:

- Inspect for an aftermarket electrical device(s) (such as an inverter, battery charger, CB radio, etc) interfering with the RF signal from the tire pressure sensors when the ignition switch is ON (II).
- Vehicle must be driven for 3 minutes at 15 mph (24 km/h) or more for DTC 32, 34, 36, or 38 to set.

1. Turn the ignition switch to ON (II).

2. Check the DTC indicated to the tire location to make sure the wheel is a TPMS type with the tire pressure sensor.

Sometimes, a USB cigarette adapter can put out enough RF noise to interfere with the tire pressure sensors.

Very true.

The OP should disconnect ANYTHING plugged into the cigarette lighters and see if the fault goes away.

Radar detectors and cameras are also known offenders.

Often, a different brand of charger will resolve the problem. IIRC, one poster had issues with a Verizon branded charger, but any brand can cause issues.
