I will happily continue clearing the message if it guarantees I'll be in your situation with 200k+ miles. Right now I'm at ~160k and trying to keep everything maintained.

I'm praying someone has had a module issue they've fixed and can share something about their experience.

I bought this with 205k, turned 213k today, I lucked out with a great previous owner who was diligent with necessary maintenance and didn't sweat the things like this that didn't impact reliability. Keeping maintenance going as he did and fully expect to get a few years out of it yet with little concern. Eventually things will wear out but saving $800 a month on a payment makes it easy to fix things.

An interesting tip I saw on these forums for computer faults is to disconnect the PCM plugs on the firewall under the hood and to spray them with WD40, then reconnect (make sure your battery is disconnected first, though!). Sometimes it's something as simple as a communications error due to a buildup on the pins...

Funny that this topic came up, as my Expy started popping a "tire pressure low" error message every time I start it since last week (no indication as to which tire, though). I attribute it to a probably dead battery in one of the senors, myself... as the temperatures have dropped below freezing quite suddenly out here and an already weak battery most likely crapped out. We shall see in the spring, lol... and THANK YOU FORD FOR MAKING THE TPMS BATTERIES NON-REPLACEABLE ! :mad:

Oh, how I miss my 99 Explorer with no ******** TPMS, no electronic throttle body and no VVT solenoids / cam phasers... all these mandatory nanny state "safety / fuel economy rules" are a royal and expen$ive pain in the ass each and every friggin time!

:banghead:
I've never heard of wd40 on electrical components but the circuits are just metal so I guess it makes sense.

I'm going to google this a little first then give it a try myself. I don't think it will work but I'll try anything at least twice.

Thanks for sharing 762mm

I found there is something like 'CRC QD Electronic Cleaner' a friend has used it on one of his automotive connections with success. I may attempt this before going WD40 on it

Edit: I see now that wd40 makes a specialist electrical contact cleaner spray. It's $7 a can, the other cleaner is $5 a can. Both are available with Amazon prime.

I'm going to order CRC electronic cleaner since it's a bigger can, cheaper, and my friend at work has used it before.

I'll keep you guys posted. Might take a few days

Meh, I just blast all electrical plugs with regular WD40 on all family cars / trucks whenever I disconnect something. It hasn't hurt anything yet. I believe it says it's good for electrical connections on the can itself, actually... Just make sure to shake the plug a bit before reconnecting, to get the excess out.

I also like to insert and pull out the plug at the socket a few times to work the WD40 in and clean any buildup on connections. So far on the Expy I've done the MAF, spark plug coil plugs and injector plugs this way. I've done the rear and front light bulb sockets too. I like to finish the job with a bit of dielectric grease in each connector plug at the end too. I'm gonna do my PCM plugs as well when time allows, as preventive maintenance.

:)

The other thing you may want to check is whether the ground is good on the TPMS module itself. A few have reported weird possession-like stuff happening to their Expy's instrument cluster, etc due to bad grounds.

You can pick up the crc contact cleaner at lowes and Walmart. I use it somewhat frequently. Just went through a half can doing diagnostics on a heat pump. Board and contactor covered in a decade of dirt and cobwebs...

It goes pretty quick, fair amount of pressure and just blasts dirt away

I literally just fixed this issue (had the exact same message pop up every time) on my 2011 EL XLT. Used FORSCAN to change the code on the instrument cluster (IC) side of things and it was a snap. You can create a free temporary FORSCAN account and get a cheap cable from Amazon.

Do you remember what you changed the code to and from? I'm going to download forscan right now and see what I can do.

I've downloaded Forscan lite and I used the Bluetooth OBD2 adapter I already had. I ran a test on the instrument cluster and 3 resets. I was unable to clear the message. I ran the reset twice and cancelled it once (for a total of 3 attempts). Forscan reports no errors.

I believe he’s talking about using the full software on a laptop and just turning off the alert, not 100% though.
