Long story short, my TPMS light has returned, this time blinking (meaning possible faulty sensor?) regardless why, I'm just as fed up with the system as everyone else. I've done research about it, i know there is no direct way of disabling the system, i have no interest in putting a "pressurized tube" in my trunk with the sensors, putting a piece of tape over the light (ghetto) or sourcing a DDM/cluster and reprogramming from a pre-2008 seems costly/too much hassle. Has anyone successfully de-soldered the surface mount LED from the cluster with no side effects? I'm handy with a soldering iron, but i want to know if removing the LED would cause the computer to detect it was missing and throw some kind of code and cause the engine light to come on, etc...?

I took the cluster out, removed the face, and painted the back of the cluster face black where the TPMS light was. Can’t tell it’s there

Wait what. I disabled my TMPS light in my P7B with ForScan.. not really disable, but like changed the settings where what psi it would trip the light on. It’s been off for months now after I did this.

that would only alter the pressure at which the light is triggered wouldn't it? i don't think it would make a difference if it was a faulty sensor. I'd be willing to go that route since i saw in another post someone was able to disable the tpms light completely via Forscan, this might be the best solution long as the light just stays out, i might order one of those usb to odb2 cables, if i could see exactly how the light was disabled would be great, would save me from having to tear things apart...

I’m not exactly sure to be honest. I always had the dumb tmps light and I was told it’s because my wheels ain’t got the sensors in them? I never cared. But the light was always on. While enabling keyless entry, I searched around and found some stuff on here and Reddit on changing when the light would come on at what psi. It was set to like 20 or something and I changed the value to a different number. I think I put a zero for the value and my light hasn’t come on since. I’ll try to dig around and find where exactly I went, so it saved me some money, and took a whopping 5 minutes. Of course, finding the exact info where to go took a bit; but that’s a whole lot better than taking the cluster out.

Yes i agree, i might go ahead and order an obd/usb cable from Amazon, i saw a couple youtube vids where you change some values to all zeros to disable the light, but something more specific to a GMQ/Crown Vic would be helpful as well if it differs

Ah that’s helpful, I’m going to get the cable and report back, any other values I should check for in ForScan?

I mean, watching the stats of your vehicle is pretty nice. Trans temp, coolant temp stuff like that. That’s the only thing I can think of but maybe others will chime in.

I bought a cheap OBDII Ian adapter from Amazon for like 18 bucks and it worked fine.

OK cool. on the side, does anyone know if the batteries in the sensors are replaceable? The sensors look to be permanently sealed so probably not I’m guessing, shame because they aren’t cheap either, mine are the blue banded ones

No, they are not replaceable. They are encased in a resin.

You can in fact disable TPMS using FORSCAN. This is not done by editing the DDM programming (as that only allows you to change the pressure setting), but by disabling TPMS in the instrument cluster programming.
There's a spreadsheet in the FORSCAN forums that'll tell you what data point to edit.

Or, simply remove the LED like you asked.
If you're interested, you can swap all the LEDs for another color. They're 3528 SMD LEDs.
I converted my cluster to blue and white (using the clear needles from a Grand Marquis/Towncar). Also swapped in a civilian message center cluster.

Searching through another thread, this user seems to have accomplished this through the IC settings and simply changing one value to "0" could it really be this easy? see photo...

Well last evening the light decided to go out, i still suspect a sensor is on the fritz so i wouldn't be surprised if it returns soon. The usb/obd2 cable arrived and Forscan was able to detect my vehicle make/model/vin and save the profile however i have to wait to get a free extended license from Forscan to alter any settings. BTW... how many miles does it take for a sensor to reset? does the spare have a sensor? (spare was very low on air) the light didn't go out until about 20 miles after it first came on. maybe i can use my basic code scanner to at least clear all the saved error codes in the meantime?
