My March 2015 reg Fiesta is showing the " Tyre Sensor not recognised" warning, so I guess it's time for new sensors.

The display unit is the type that shows only a low tyre pressure warning but not the actual pressures.

Has anybody got useful tips for sourcing compatible items, and/or knows the Ford part number?

Is there any way to identify which one is the failing one and after replacing it, is there any reprogramming to undertake?

But--has anyone had any success with DIY battery replacement modification as a cheaper option?

Any advice would be appreciated, please.

Have you tried resetting tpms I get this warning on mine sometimes but a reset fixes it.

These should be what you want.  Kwik fit done mine for free when i changed them over, just gave the guys "a drink"

Hello

Have you had new tyres or alloy wheel refurbishment on your car and if so did they put the sensors back in?

I had the same problem and it turned out i had the wheels refurbished and the sensor hadn't been put back in. Luckly i wasn't paying for it because my main dealer (Pye Motors Morecambe) charged £115 to replace them.

At least they are made with good quality parts. Spoke to a tyre fitter and they said Chrysler/Jeep/Dodge sensors are the worst but Ford/Vauxhall sensors last ages.

hope this helps

Thanks.

No recent tyres or wheel changes so something new going on.

A reset did remove the warning, but it returned. (I did check tyre pressures, but this is not the same warning as when a tyre has deflated) As the sensor is "not recognised," I guess it is not transmitting. Is there any quick way of identifying which one is the faulty one?

Just for my information, where is the receiver situated that gets the sensor transmission?

Could just be a dead battery in a sensor.

Yes, that's very likely!

So How can I identify the faulty one and has anyone had success with a DIY battery replacement instead of a new sensor?

Does a new sensor need training/pairing to the car?

Thanks, but those are used ones; I would not expect them to last long.

When i change my wheels, 16 to 17, i brought new sensors in Ford dealership, 30€ a set of 2.

Is not that much for some people, but you will know that works.

Just showing what type you need. Ford ones last longer go and pay their prices

Thanks for the responses.However for the benefit of any others who come across this problem, here is the result of my research and experience.

There is a lot of misinformation on the web and from tyre fitters. The costs involved are varied. (Main dealer looking for over £100! and Kwik Fit for £80}

There are two slightly different sensor types.If you have the system that identifies which tyre is at fault it is easy to do so, but if only a general warning is available, then it will require a 5 minute check with a specialist tool. (Not just an OBD reader). Some fitters and my Ford dealer will do this (reluctantly!) for free. (A drink would be nice!)

The sensor can be purchased from £8 (china) up to £50ish on line. Around £18 looks competitive, but see later for coding costs. There are two interchangeable fitting styles to put it onto the rim; one uses a metal valve stem with a retaining nut  and the other a push in rubber (non-corroding) valve stem. There are various shapes of sensor housing  design, but all are OK. Removing the tyre, fitting the new valve & sensor are straightforward, (£6 at my local tyre shop)  .

Coding and pairing.----the sensor needs to be coded with its own individual identity/transmission code.This can be done with a specialist tool (again not an OBD reader)  "TPMS Warehouse UK" do this on request free with a purchase. Their sensor was £25 incl delivery.

Once fitted, I did the following, Inflate to correct tyre pressure then ( as in the car specific guidance supplied on line by TPMS Warehouse.)----  Close doors, press brake pedal & release. Use ignition key to switch on (NOT START) dash lights, switch off, switch on & switch off again, then switch on. Press and release brake pedal and then switch off. Repeat the triple switch on/off cycle, ending with brake press and switch off. Horn bleeps. Process completed. (This process does vary slightly with different models)

All seems good so far at a total cost of £31.

I am not on commission,  but I was impressed with the help given by phone by TPMS warehouse.

Further comments---Some on-line information suggests that the individual sensorcoding is not needed and that either the process stated or even just resetting the infotainment display and then driving for 15 mins will suffice. I don't know, but as the coding is available, why not do it and be sure.

Regarding battery replacement----I dismantled the old sensor. It is not designed for this, but the glued housing  can be seperated and the electrics eased out. The battery is one with "legs" to solder onto a small PCB but is NOT a standard button battery as it is a High temp long life version with the legs. Availability seems to be zero in the UK, which is a shame as replacement would be relatively easy and inexpensive for a DIY job. Indeed the design seems to be meant to thwart routine battery replacement, although this looks as though it will be an increasingly needed task as the first generation of these sensors starts to run out in the UK.

Hope others benefit from my experience.

The sensors i brought in Ford as like this (pic) with rubber seal, 60€ 4 sensores

Just did a reset in center console and work perfect.

This sensor monitor the 4 tires, if any drop 0.3 psi, you will get a warning.

With that sensor you will get a warning about which tyre is faulty?

What is the shape on the flip side?

ADDENDUM-----I have been told by those helpful folk at TPMS Warehouse that this sequence does not always work on some models, but if so, any garage with diagnostics can edit the coding to insert the identity of the new sensor. Their invoice gives this identity  number
