Thread: Faulty Tyre Pressure Sensor, 2015 Ford Ranger

A question for those knowledgeable of such things. I haven't asked my local Ford dealer yet but I'm pretty sure they would want to charge me a hefty cost which I would like to avoid if possible.
This Faulty Tyre Pressure Sensor light has been showing for a couple of weeks but the tyres are properly inflated so I suspect the sensor battery has died and a new sensor is needed.
Do I have any reasonably priced options for scanning to find the faulty unit, obtaining a replacement and having it synced to my vehicles computer ? I'm not too bothered if a replacement is an aftermarket rather than Ford branded item, unless there's some huge disadvantage.
Any thoughts, suggestion, recommendations much appreciated, thankyou.

Have you checked the pressure in the spare tyre?

Good question. No, not recently but it was checked probably early 2025, after no checks for several years, and it needed only a little air.
Will check again though just to eliminate that possibility.
Thanks.

The reply from @Savage1 brings to mind another question.
If the spare tyre Sensor is fine and working and the faulty unit located in one of the driving tyres could I replace the faulty sensor with the one from the spare tyre ? If so, I presume it would alsready be synced to the computer ...

Tyre place replaced a tyre sensor for me. Fault light on when I went to leave. Tyre guy jumped in and reset something on the dash board and I was away.

Thankyou. If you don't mind my question do you remember the cost ?

Have you tried doing a pressure reset in the vehicles menu

No, but it wasn't expensive.

Google says the part is $69 through Ford.

Yes. I did a Sensor reset. Don't think I can do a pressure reset ( ? ) although in some models I believe that can be done. The first time the reset extinguished the light for a few hours. Since then further resets haven't done so.

Thanks again. Good info.

Chalk another up to excessive gimmicky electronics.
Hope its as easy as deleting the sensors.
Good luck man.

You're not wrong. Yeah, I'm hoping it's easy too. Cheers.

My mates 2017 ranger had a similar problem. It caused the car battery to go flat . He couldn't start or anything
Diagnosis was battery flat inside the tyre pressure sensor. He mentioned they removed the tyre changed battery.then all good. I'm not sure if it requires a reset but anyone with a obd scanner can probably do. As we speak I'm about to head outside and reset my work van hiace oxygen sensor

Thanks. Yeah, pretty sure the Sensor battery is dead. Have read the battery is integral so likely a whole new Sensor needed. My vehicle battery is new ( renewed 3 months ago ) so if there's any drain maybe not too great.

Yeah the sensor i belive has a replaceable battery in it. Not sure on type so it's a matter of removing tyre and replacing sensor battery in rim
