    I am trying to fix this myself. Is there a test or process, other than having to take it to a third party, to allow me to detect which tire sensor is at fault? How can I, myself repair this sensor? Is this a repair that can only be done by a dealer?

    You can start by jacking up the car and removing the front tires. Try to look for loose wirings for this can trigger the fault.

Tire Pressure Monitor Systems (TPMS). If you see this TPMS icon illuminated, it means your vehicle has a low tire. STOP, and check the inflation pressure in your tires. This warning light will come on if tire pressure in any of your tires falls more than 25% below the recommended inflation pressure (refer to your owners manual, or the tire inflation decal in the glovebox, driver door pillar or gas tank filler cap lid for tire inflation pressure recommendations).
The TPMS warning light should come on for about one second when the ignition key is first turned on for a bulb check. It should then go out if all of the tires are properly inflated. If it does not go out, or it comes on while driving, you have a low tire.
NOTE: If the TPMS warning light is flashing, it indicates a fault has been detected in the TPMS system that will require further diagnosis. Common faults include a bad tire pressure sensor, a defective keyless entry receiver module, a fault in the TPMS or body control module (BCM), or wiring problems in the keyless entry/TPMS/BCM circuit.
Tire Inflation Pressure Monitor Systems (TPMS) are being used on more and more new vehicles. Low tires are potentially dangerous, especially if a vehicle is heavily loaded and traveling at highway speeds during hot weather. A low tire under these conditions is a blowout waiting to happen. The inflation pressure of the tires should be checked regularly, but many motorist do not check their tires. That is why Tire Pressure Monitor Systems are coming into use.
Tires are designed to operate within a certain pressure range. The recommended inflation pressure can usually be found in the vehicle owner's manual and on a decal that may be located in the glove box or door jam. The recommended inflation pressure is designed to give the best combination of ride comfort, load carrying capacity and rolling resistance.
Increasing the tire inflation pressure reduces rolling resistance (which helps fuel economy). It also increases the load carrying capacity of the tire. But it also increases ride harshness. The maximum inflation pressure (which can be found on the sidewall of the tire) should never be exceeded because too much pressure may overstress the tire and increase the risk of tire failure.
Decreasing the inflation pressure improves ride quality by making the tire softer. Under certain circumstances this may help improve traction a bit. But lowering the pressure also reduces the tire's ability to carry weight and increases rolling resistance (which hurts fuel economy).
A low tire also wears faster. Why? Because increased rolling resistance and flexing in the tread scrubs away the tread. As the miles add up, so does the wear and eventually the tread is down to the wear bars. Once the wear bars are flush with the surface of the tread, the tire needs to be replaced.
The increased friction in the tread and the sidewall that results from underinflation also generates heat. All tires are engineered to operate within a certain temperature range, which you'll find on the side of the tire (A, B or C, with A being the best). When a tire is underinflated, it runs much hotter than normal. This may or may not create a potentially dangerous situation depending on how low the tire is, how fast the vehicle is driving, how heavily it is loaded and the ambient temperature. The lower tire, the more heavily loaded the vehicle, the faster is is traveling and the hotter the weather, the greater the risk of a blowout.
A blowout can have deadly consequences because it often causes the vehicle to lose control. If the blowout occurs on a vehicle like a truck or SUV with a high center of gravity, it greatly increases the risk of a rollover.

There are essentially two basic ways to monitor tire pressure electronically. One is the direct method. A small pressure sensor is located inside each wheel. The sensor has a built-in transponder that broadcasts a radio signal to an external module. The module identifies the signal from each wheel and keeps an eye on pressure. If pressure drops below a predetermined threshold, the module turns on a light or displays a message to warn the driver. IN short get your tires checked. Thanks.

2009 f150 TPMS fault

When the sensors were replaced and they did a reset. They should have told you the problem. They should have told you up front, instead of charging you for sensors. The BCM isn't reading the signal from the sensors. Find another place to go. I hate point and fix mechanics. Sensor fault? replace all the sensors... It didn't say one tire, it says sensor fault. Have the codes read. They should have done this. To get rid of the message on the DIC, you have to unplug it. But this gets rid of all messages you would get. Pull the IP and take it apart to unplug.

Brake fault and tyre pressure fault comes on dashboard and beeps intermittently very annoying as no problems with either

The car management system is reading it as a fault. Could be faulty sensors giving incorrect readings. Have it scanned and see what fault codes come up. Sometimes resetting the faults fixes it, but usually if nothing mechanically wrong then the sensor wiring may be faulty (water ingress, bad soldered joint or connection etc.)

Tpm reset 2008 isuzu i290

it resets every time you key on.
the Tire pressure monitoring system. TPMS.
on good cars, the system tells you exactly what is wrong.(dash)
EG, my jeep shows, R/F tire bad. so replace that sensor
or if tad older car,? i must use my scan tool to see which sensor is failing, on mine even the spare must work.....

so if no scan tool and a "intellectually challenged")ECU.(PCM) per above....
then what to do, tool-less? (no scanner tool for pcm no scan for TPMS)
you go to any tire shop in town, and say, scan my tires.
we have this scanner and wave it over the stems.
omg one is dead.
or one reads wrong fibs.
or other errors.... (over temp, serial wrong, etc)
it's just a battery powered sensor. on each rim stem.

that be about it....

What does tire fault mean on my dash

This should mean you have a low tire or several low tires. The pressure information for front and back tires is on a label on the doorjam. If filling the tires does not help, a sensor may have broken. Each wheel has one and a tire store would need to find the defective one.
You may get help at Autozone, Advance, or Oreilys autoparts for some free scans. Can not say if their scanners cover this rare feature.

The code description is Front Steering Position Circuit. Your traction system has detected a fault in the steering controls system. Try driving on a straight line. Did you notice a pulling on one side? You will need to check tire pressures, proper tires, and brake system conditions. Is your steering wheel off center? Your vehicle may need wheel alignment. These are the least you can fix by yourself without a scan tool. With a scan tool, the recommendation could say a faulty sensor or module, or a wiring concern. My tip for you, the most common culprit is the steering angle sensor.

Okay, sir? goodluck and drive safely. : )

My service tire monitor came on.what does that mean

That means a sensor has detected either a low pressure situation in one or more of your tires or it is time to replace your tires. In any case, you need to bring your vehicle to a shop, preferrably a tire specialist shop, and have them look at it.

ESC not working

Your question is kind of jumbled, but I believe I had a similar problem. The ESC would not function properly and the button on the dash would not work sometimes. I took it to the dealership and they had to replace a speed sensor on one of my tires. That fixed the issue and maybe it would also fix yours. Hope this helps.
