Info On Tire Pressure Monitoring Systems (TPMS)

[spikedog]

Look at my post #89 above for resetting the clamp and band style (2006 to present). Buy the tool from Ford.

The tire pressure monitoring system (TPMS) monitors the air pressure of all four regular road tires. The wheel-mounted tire pressure sensors transmit via radio frequency (RF) signals, to the TPMS module (integral to the vehicle security module (VSM)), using the valve stem as an antenna. These transmissions are sent approximately every 60 seconds when the vehicle speed exceeds 32 km/h (20 mph). The TPMS module (integral to VSM), compares each tire pressure sensor transmission against a low-pressure limit. If the module determines that the tire pressure has fallen below this limit, the module communicates this on the controller area network (CAN) to the instrument cluster, illuminates the TPMS indicator and displays the appropriate message center message.

The system is not affected by wheel and tire rotation.

Sensor Training (Reset Procedure)

NOTE: The tire pressure monitoring system is not affected by wheel and tire rotation.

NOTE: The tire pressure sensor training procedure must be done on a single vehicle, in an area without radio frequency (RF) noise.

RF noise is generated by electrical motor and appliance operation, cellular telephones and remote transmitters, power inverters and portable entertainment equipment.


1.Turn the ignition switch to the OFF position.
2.Turn the ignition switch from the OFF position to the RUN position three times, ending in the RUN position. Do not wait more than one minute between each key cycle.
3.Press and release the brake pedal.
4.Turn the ignition switch to the OFF position.
5.Turn the ignition switch from the OFF position to the RUN position three times, ending in the RUN position. Do not wait more than one minute between each key cycle.

6.The horn will sound once and the TPMS indicator will flash if train mode has been entered successfully. If equipped, the message center displays "TRAIN LF TIRE", place the magnet on the valve stem of the LF tire pressure sensor. The horn will sound briefly to indicate that the tire pressure sensor has been recognized by the TPMS module.
7.Within two minutes after the horn sounds, place the magnet on the valve stem of the RF tire pressure sensor.
NOTE: If the VSM (TPMS module integral to VSM) does not recognize any one of the four tire pressure sensors during the tire training procedure, the horn will sound twice and the message center (if equipped) will display "TIRE NOT TRAINED REPEAT" and the procedure must be repeated.

8.Repeat Step 7 for the RR and LR tires.
When the tire training procedure is complete, the horn will sound once and the message center (if equipped) will display "TIRE TRAINING MODE COMPLETE".

PS. Your spare tire does NOT have a TPMS sensor in it, so if you put on the spare, you'll get a dashboard light soon.

Hi,

two of the 4L2T-1A150-BA sensors on my Ford Explorer 2005 are broken (the aluminium valve was corroded and broke during tire change). The local dealer is selling them for about $120 a piece. As I suspect the other two are on the verge of their life span I need 4, and Im not thrilled at spending $480 on them !

So my question is, where can I buy them the cheapest ?

Has anyone experience with "Orange Electronic Original Equipment (OE) compatible TPMS sensors" part "SC50BA" ?

I'm surprised no one has come up with the obvious fix to these systems. Just drill 4 holes in a metal plate, & mount all 4 sensors to it. Then weld up a box around them & pressurize the box. Then place the box under a seat (or get all fancy & mount it up under the dashboard) & install whatever rims you feel like.

2005 Ford Truck Explorer
Sensor Training

1. Turn the ignition switch to the OFF position
2. Turn the igntion switch to the RUN position three times, ending in the RUN position. Do not wait more than two minutes between each key cycle.
3. Press and release the brake pedal
4. Turn the ignition switch to the OFF position.

Does anyone know how to retrain (relearn) the TPMS sensors on a 2011 Explorer? There's no ignition switch! I'm looking at a Tire Rack winter tire & wheel package, and would like TPMS functioning.

2003 Aviator here...same basic system. I think. I did the three run, brake(and e-brake), three run, and got it into "training mode". Took a fairly strong tweeter magnet(peerless soft dome), and followed the dashboard instructions, train LF, train RF, train RR, train LR, and train spare(all in one sequence, not front axle rear axle like others I have read about here). The magnet sounded the horn after rotating it around each valve like it should, even the hard to get to spare honked the horn almost right away. System message was "training complete". YAY!

Wait, no, turned back to run, and before I even started it, I got "very low tire message"......GGRRRRRRR!!!

Any ideas? The spare might have been a little low, but before I would get a spare tire low message, not the very low tire message(which dings about every 30 seconds....impossibly annoying). FWIW I just had a new TPMS installed on left front...the tire had a slow leak and im pretty sure the grommet on the sensor was it. It was, along with the flaking chrome on the stock rims. Shop cleaned it up and got me setup with tire reinstalled and bead cleaned. They did warn that if one went bad the rest might be close to going bad soon. But all hold air just fine....for now.

Any ideas? I would have to drop the spare to air it up. We dont drive it enough and have free towing, so we dont even use the spare...should I just bite the bullet and air it up? Getting chilly around here these days, less time outside on the cold ground the better....(I'll get a heated garage one of these days....lol)

Try lowering the air pressure and raising it,then retrain.

ill let you know tomorrow.

Sorry for not getting back to this post earlier.......

I didnt have to do a thing. Got PO'd....went inside and called it a day. Two days later I got in and PRESTO!!!!! no tire extremely low....but still got the spare tire low(again dont care....no constant dinging). Will eventually get the spare right....maybe. Would rather get a set of murdered out 20's and do the rest the faded "grey" in the same color.

I did my dodge v10 with a "pole kit" that I had to put on....personally love the look. Sorry for the sacrilege....my toy (or broke down lincoln...lol....hauler)....

yeah....its not finished.....ignore the rusty lugs/hubs...and think lower...

I did it today it worked perfect! I got this one http://www.amazon.com/gp/aw/d/B001UCCNI4

TPMS will not enter programming mode

Howdy,

I just installed an alarm...let the gremlins fly! The battery was disconnected for about a month. upon re-initialazion, the alarm works fine. The TPMS low tire pressure indicator comes on during the initial check, and will not got out. It is solid. I have tried to enter reprogramming mode to no avail. Things i have tried:

Before attempting to enter reprogramming mode (O/R X3, brake, O/R X3)

pulled fuse on alarm
wake SJB with factory remote
ping Sensors w/magnet
drive for 5 mins

Just will not enter reprogramming mode.

Any suggestions?

Thanks

This sounds like a job for black tape on the display and electricians putty shoved into the dinger.
(I could remove the light behind the display symbol and unsolder the dinger, but that requires some real work.) This method worked on my '96 Aerostar and it will work on my '05 Exploder.

I have been checking my own tires for 50 years and I don't need some computer telling me to spend hundreds of dollars to repair a system that was intentionally designed to fail when the battery in each sensor gets low. I am completely fed up with people who think making up lots of new laws will cure stupidity. The idiots that can't or won't check their own tires will just ignore the flashing lights and annoying noises...or press the reset button every time they start the car.

If you're too stupid or lazy to check your own tires, Darwin will weed you out. Problem fixed.

The TPMS sensors require movement to wake them up and do their job. They go dormant when you park. That's how the batteries last 10 years. I've heard of folks putting the sensors in a length of PVC pipe with a Schrader valve, pumping in air and throw it under the seat. Not only does it not work, it looks (and acts) like a pipe bomb....under your seat.
