TPMS system intermittently working

[ryan2100]

I have a 2018 JL That I bought in June 2018, I put aftermarket 35s and 18in rims on, day 1 of purchase. The Tpms sensors worked great with no issues for 3yrs. However, 2yrs ago during a rainy Colorado winter day the sensors randomly stopped working on all tires. However, over the past 2yrs they will intermittently work again when I start the Jeep, and work for day or two, reading all pressures just fine. Then it stops working again. It’s never a single tire, it’s all of them or none of them. Any thoughts or solutions? .

Most likely water intrusion into your TPM module or the TPM module itself is failing. Replace it and inspect the connector for corrosion while you're there.

awesome thanks. Yes it definitely started after I drove through a big puddle. I’ll google it but, any idea where the Tpm module is located?

it's on top of the rear frame rail
