13dreamz Posted July 31, 2011 Share Posted July 31, 2011 I have a 2010 Fusion and every now and again while driving the warning comes on of a Fault in my tire pressure system .... I tried retraining it but it keeps telling me failed to repeat ... I'm assuming I have a bad sensor in one of the wheels .... my question is how can I figure out which one it is?

Thanks for any help .... Hi 13dreamz. :D We have too little information and far too many variables to give reliable troubleshooting assistance (well, in my opinion anyway). Assuming your car is still covered under the 3 year/36,000 mile Bumper-to-Bumper Warranty, my best recommendation would be to let your Dealerships Service Department properly diagnose and repair the issue under warranty. Keep us updated and good luck. :beerchug: Edited July 31, 2011 by bbf2530 0 Quote Link to comment Share on other sites More sharing options...
13dreamz Posted July 31, 2011 Author Share Posted July 31, 2011 Thanks I will do that ... 0 Quote Link to comment Share on other sites More sharing options...
2011se25 Posted August 2, 2011 Share Posted August 2, 2011 When training the sensors, which one does it stop on when it gives you the failure message? Try starting with a different wheel to confirm that one is bad. 0 Quote Link to comment Share on other sites More sharing options...
13dreamz Posted August 2, 2011 Author Share Posted August 2, 2011 All it says is training LF Tire then says Failed while I'm trying to train it ... I then rotated the tires and it does the same thing.... unfortunately my fusion is the SE and all it has is warning light that will flash and on the odometer is where it reads the fault ... it doesn't give me the specific tire besides LF ... 0 Quote Link to comment Share on other sites More sharing options...
2011se25 Posted August 2, 2011 Share Posted August 2, 2011 What tool are you using to train it? This one? Are you pointing it by the sidewall by the valve stem? Even though it says LF you can start with RF, RR, LR 0 Quote Link to comment Share on other sites More sharing options...
13dreamz Posted August 4, 2011 Author Share Posted August 4, 2011 (edited) What tool are you using to train it? This one? Are you pointing it by the sidewall by the valve stem? Even though it says LF you can start with RF, RR, LR No I'm not using that tool I had called the Ford Dealership and this is how they told me to do the training ....... Check the tires before you reset the tire pressure sensor to ensure you inflated the tires with the suggested tire pressure according to the owner's manual. Turn the ignition of your Ford to the "Off" position. Press and release the brake pedal. Turn the ignition to the "Off" position. Switch the ignition from the "Off" position to "Run" position three times as you did before, ending in the "Run" position. The TPMS light will flash and the horn will beep if you performed this procedure correctly. If your vehicle has a message center, you will see "Train LF Tire" as the TPMS learns the new pressure settings. Then the message "Tire Training Complete" will appear on the display. Turn the ignition to the "Off" position to verify the training's success if your vehicle does not have a message center. Repeat the entire procedure if the horn beeps twice after you turn the switch to the "Off" positIon....... The display then says training LF Tire and it continues for roughly 2minutes and then horn beeps twice and Then it will display a message saying .... could not train please retry ....

VonoreTn Posted August 29, 2014 Share Posted August 29, 2014 Note that your tire warning light will be flashing on and off if it is a system failure, which does include one or more tire pressure sensors giving no signal. But if there is a real low pressure signal coming in and all 4 sensors are good, you will get a solid tire warning light. You can determine which tire sensor is the one not giving any signal by lowering the pressure in each tire below 20 psi with the others all up to pressure, and noting if the resulting warning light is flashing or not. It will be flashing only with the tire that is not sending a signal, the others where the sensor is working will result in a solid, non-flashing tire warning light when they are below 20 psi. Whenever you have the spare tire on, the light will be flashing, because the spare gives no signal. Unless you also have very low pressure in another tire. 0 Quote Link to comment Share on other sites More sharing options...
VonoreTn Posted September 29, 2014 Share Posted September 29, 2014 I am getting smarter about controlling the cost when a tire pressure sensor goes out, this having happened twice now, 2 different tires in 100,000 miles. The sensors are advertised as lasting 150,000 miles, but how would they know the actual battery life? For my car, the tire sensor part I need is this one: Schrader Automotive part # 20315, $37.79 at Rockauto.com. And I found a local tire place Pauls Tires, Loudon, Tn, where he has the tool to determine which tire it is, and his display told him to reset it exactly as 13dreamz described above. Thank you 13dreamz. Paul charged me $15 for his service, including diagnostics and replacing the sensor that I provided him. Using his diagnostic tool which had a display, he confirmed the bad sensor was in the left rear tire, as I predicted, using the above method that I described. 13Dreamz, if you are still around this forum, how much does that tool you show above cost? That tool would save me the steps of relieving and refilling the air in each tire. 0 Quote Link to comment Share on other sites More sharing options...
FusionDiffusion Posted September 29, 2014 Share Posted September 29, 2014 I think the TPMS tool is about $40 on eBay/Amazon. I have one. If you also get an ELM327 and use FORScan you can diagnose the TPMS faults yourself and read the pressures from the sensors. 0 Quote Link to comment Share on other sites More sharing options...

If you also get an ELM327 and use FORScan you can diagnose the TPMS faults yourself and read the pressures from the sensors. Thanks for the info. I found this at Amazon, at http://tiny.cc/wwfhpx Which looks like the same tool you show above, for $34 +. http://i911.photobucket.com/albums/ac317/vonoretn/FFH/TPMS19remote_zps31feee40.jpg On the above photo, do you know which of the two tire TPMS's are the correct one for a 2010 FFH? They have different Ford part numbers. I'm guessing the 9L3Z-1A189-A. I am already using a Schrader TPMS on one wheel successfully, part # 20315 that I got from rockauto.com for $37.79. I noticed on the comments from Amazon on the above tool that someone said it wouldn't allow him to reset the car, but then he figured out that if he let air out of all the tires to below 20 psi, then added back to the spec. psi, it would reset. Like the sensors had to be cycled once. 0 Quote Link to comment Share on other sites More sharing options...
FusionDiffusion Posted November 18, 2014 Share Posted November 18, 2014 (edited) I think all the TPMS tools are the same. All they do is emit a 125 kHz radio signal to wake up the sensors. If you can't get the sensors to trigger on the tire sidewall, try holding the tool next to the valve stem. Rapidly releasing air from the tires is another way to wake up the sensors. I'm not sure on the TPMS part numbers (call a part department), but I think they likely will all work the same as long as they look similar and are Motorcraft.
