TPMS sensor error

[edgemaster]

About a year ago I had new tires/rims installed. A month ago this "TPM sensor error" message showed up in the dash. The tire guys told me all sensors are OK, reset them via OBD II. Now the message is back again. It appears that one of the sensors is not OK, right? Do I have to live with that resetting every couple of weeks? It's an 80mi roundtrip each time.

What's the age of the sensors?

 

No need to travel to a tire shop to do the Re-Learn procedure.

 

$15 device is what I use.

What is the Model and Year of your Edge? - please add it to your profile signature - https://www.fordedgeforum.com/settings/signature/

Thanks, my Edge is a 2009 LTD. I'm assuming the sensors are new, installed a year ago with the tires/rims.

Unless asked, a tire fitment shop isn't going to install new sensors with new tires.

 

The pro level tool that good tire shops have can also assess the sensors battery level.

 

These sensors are very reliable, and when they go bad its usually the battery that's reached it end of life, which is around 5 to 10 years.

It was Discount Tire and they told me they had installed the sensors.

Do they show on the invoice?

 

If they're on your invoice, check what kind of warranty they have.

As I said in my original post, I was there about a month ago with that same message in the dash and they did reset or relearn or whatever and the message was gone. So, I'm pretty sure they're installed.

No doubt that they're installed, but who knows how old they are?

I spent $1600 so I m assuming they are new. I'm sure, if I'd ask them they would swear up and down they were new.  I've ordered one of those gadgets that you recommended. Thanks for all the input.

I have a 2010 SE which doesn't have a message center, so when a tire loses pressure a light comes on and I have to figure out which one is bad. If you have a full size spare or one of your old wheels you could try putting it on one wheel at a time and see if your message changes. An easier thing to try would be to let some air out of the tires one at a time and seeing if you get a low pressure warning for the tire you're working on. If you get a warning, then the sensor is working. Don't forget to air up before you go to the next tire.

I'm getting ready to rotate my tires and my new spare. I was reading up on what Haz posted for me in another thread and came across this:

 

TPMS indicator FLASHES for 70 seconds and then remains ON solid when the ignition key is turned to the ON position, the message center (if equipped) displays TIRE PRESSURE SENSOR FAULT and DTC B2872 is present Intermittent TPMS operation due to Radio Frequency Interference (RFI) TPMS sensors not trained Not all TPMS sensors are installed TPMS sensor(s) SJB NOTE: If the vehicle has been stationary for more than 30 minutes, the sensors will go into a "sleep mode" to conserve battery power. It will be necessary to wake them up so they will transmit the latest tire pressure information to the SJB . ACTIVATE the TPMS sensors. REFER to Tire Pressure Monitoring System (TPMS) Sensor Activation in this section. GO to Pinpoint Test F. TPMS indicator FLASHES for 70 seconds and then remains ON solid when the ignition key is turned to the ON position, the message center (if equipped) displays TIRE PRESSURE MONITOR FAULT and DTC B287A is present TPMS sensors not trained Not all TPMS sensors are installed NOTE: If the vehicle has been stationary for more than 30 minutes, the sensors will go into a "sleep mode" to conserve battery power.

I got me one of those gadgets and ran the relearn procedure. All is OK now. If the message pops up again in a few weeks, which I totally expect, one of the sensors is bad, right?

[enigma-2]

Yup. I had a sensor in my 0mkx that did the same thing (the battery is designed to last 10 years). Finally got tired of this pesky annoyance popping up took the car in and got all new sensors. Talked to the service manager (guy is really knowledgeable) and discussed Motorcraft vs. chineese aftermarket. He said the get around one or more failure in every batch. The all work fine when first installed but the bad one(s) start to go bad after a few months. 

If I remember correctly, Motorcraft ran around $50 and aftermarket around half that. Plus new straps.

I bought two sensors for my BMW motorcycle and a set of four for my 2017 Sport from Aliexpress.

 

The ones for the BMW are Schrader and been in service for more than a year, and the four in my Sport have been in service for 3.5 months - no issues.

 

BMW sells the TPMS sensors for $250 each and I paid $10 each.

 

The ones you bought from a local retailer most likely came from the same factory in China as the ones I bought.

 

My "Made in China" iPhone is still going strong.

Excellent! Now to update that sig image to show the K bike

Hello.

This topic has also become more active for me. After replacing the wheels with winter tires two weeks ago, the sensor learning procedure did not end successfully, it stops on the RR tire.

Tomorrow I want to try to put a tire with summer tires during the training and finish the training.

So I want to make sure that the RL sensor is working and I only need to replace the RR sensor.

I want to ask a question why during training you can't just put a sensor not mounted in the tire.

Is it related to the pressure that must be present in the tire to pass the test?

I also do not understand why Ford makes do each training time when changing wheels and don't store sensors in memory.

 

Thanks for any comments on this topic.

You don't need to mount the tires to perform the learn process - when my new sensors were installed the tech did the learn procedure while one wheel was a fair distance away from the car on the balancer - he just walked up to it with the activation tool.

 

You don't have to perform the learn procedure when fitting new wheels and sensors - just drive about 15 miles and it will automatically link to the new sensors and their location on the vehicle - its just quicker to do the learn procedure.
