Hi, wondering if anyone can help. 

Ive recently bought and collected a focus zetec a ecoboost. Prior to collecting the garage have kindly refurbished the alloys for me but I now have a light on my dash stating that the TPMS cannot detect a sensor. I have reset a few times and it reappears after approx 10miles. 

After having a quick browse online I have come across a few feeds on how the sensor may have be damaged whilst the tyres have been removed and fitted.

also on how to retrain the sensors. I have managed to get so far with the training of the sensors but then it says tyre could not be trained. 

Any help would be appreciated 

thanks

Sensor broke then 

Funnily enough I'm actually doing this with a colleague at work for almost the exact same reasons...

 

First thing to be aware of, did the refurb place use TPMS compatible valves? Chances are if it's a wheel specialist and not a general garage they just popped in a new valve for you of their stock, without thinking about it. If it's been a couple of days one person may have taken them off and another put them on, no questions or thoughts about TPMS.

 

Secondly, again if not in the know, theres actually a tool you/ a garage would need to use to get the TPMS unit in the valve to communicate with the car when in sync mode, if you have a look on Amazon for example, the cheaper one (~£9?) Is all you need, a wand with a button. A dealer can charge quite a heft for that so don't go blindly into it being told it's a big thing, heck replacement valves are usually £95 for OEM but you again can get equivalent online for ~£15.

The process itself involves the car 'relearning' which TPMS is for which wheel, and the  pressures they run so it could even be a case that the wheel distances have changed and confused the car (OSF to NSR for example).

A garage with a tool could do it pretty quickly and cheaply and would normally (in my experience) charge about £5-10 per wheel to sync, but FWIW if the garage took them off the car working, I'd ask them to check if they took them out and replaced with normal, and if they still have them. Otherwise a new TPMS and tool isn't too much, but at the same point it's not a big cost to them to rectify either 😉
