When I checked all my tires the pressure was at 30 psi when it is supposed to be 35 psi cold.

How low does the pressure have to be for the TPMS to notify me?

Thanks!!!

from my understanding, and i have NOT tested this, but for the jeeps, i was told that the system will only alert you if only ONE tire is lower than the rest. (which would indicate a problem) but if they all are around the same, it wont alert you. in a way, this makes sens. a jeep is an off road vehicle and it is common to lower your tire pressure when off road. you wouldn't want your dash constantly chiming at you

The systems with the individual monitors such as ours will alert if one or all are low.
Those that drop their pressure for off road use look at the light all day.
Don't blame Jeep for this though......this is our government being our nanny through legislation.

There are two TPMS systems for the Commanders. The basic system, which is on the lower end models, notifies you that a tire (or tires) is low and you have to figure out which ones are low. The highend system, which is on the Limiteds and Overlands, tells you the psi in each tire and notifies you which tire is low.

i understand that. we are talking about something else. not the difference between the two...

I don't think that is true.

This is not exactly on topic, but might be answerable by the guru's reading this thread.
I just got my Commander back after the 120k check up... ouch. Of course they rotated the tires, and also set the pressure to 38psi on all 4. About 4 hours after picking the vehicle up, I got this warning "Service Tire Pressure system" and an indication that the left front tire had no pressure. Obviously a false indication since the tire was fine.

I bumped the pressure on both fronts to 40, and everything has been working fine for the past week, but I fear I have a bad sensor prompting 2 questions. How much is it gonna cost me to go with an OEM replacement? And, second, is there a viable alternative?

Thanks

The batteries in them can go weak and have weak signal. IDK what year yours is but I sell TPMS to members in here for $25 a piece or $70 a set. I can get OEM or aftermarket. The aftermarket ones for the 06 and nice because the stem is serviceable unlike the OEM ones. The aftermarket 07 and 08-10 are exactly the same as OEM just purple in color.

I have an 06 Commander top end and have only had this problem with the same wheel. I don't know what the best course of action should be, just replace the offending unit and toss the old one in the GB. Replace all 4 ? It all sounds like a PITA since the wheels have to be removed, tires dismounted yadda yadda yadda. Can you push me one way or another?

I wouldn't bother getting all four. We have some that go bad at 40 k and some last til like 110k. I wouldn't waste your money. If you decide to do all four ill sell u the set for $65 shipped just to give u a couple bucks off.

You're a peach... I will PM you in a couple days to get address for a Postal Money order if that will work.. at that price, I think I'll get a full set, keep them in the glove box until the next time I have tires replaced or pick up a nail. At least I'll have a matched set.

Thanks for the effort.
