TPMS acting up

[RonsterGT]

I have Project 6GR wheels on my '22. Getting intermittent "TPMS failure" type message.
Mostly front left, sometimes both fronts. Once was right front, right rear.

Did the re-learn using the hazard toggle and letting air out of each tire method. Reset sensors and worked for about 50 miles, then right front acted up again.

Started car today, all read pressures fine.

When I had the wheels on my '20, no problems from new to 4500 miles.

I am considering replacing sensors with OEM Ford or Ford Performance type, since I think N4S Motorsports probably uses some cheap Chinese garbage sensors.

Does this issue seem like a TPMS issue or a BCM issue?

I did do "shark fin" delete, so not sure if "satellite antenna fault" could be screwing up the TPMS system...

Thanks for any insight.

The sensors are faulty. Aftermarket TPMS sensors can be hit and miss. I would replace them with OEM.

Do you have a pic?

Is it a kit?

Thanks.

I would just replace them, its not like its super expensive anyways.

goto a tire shop. their scanner can display battery voltage

could also be rf interference from something. add any new electronics?

Had summers on last mustang in shed and read them fine in the car. Yet on the car they were intermittent. Never got to the bottom of it, but batteries were fine. did a relearn with tool and they cleared up when I put 'em on next spring

FWIW, I bought a set from Ford Performance with the training key for a second set of rims I'll be using. I do understand there should not be any difference; they should be universal. Software/electronic-like items, I prefer OEM.
