Need help with TPMS!

[ebrarceliktas]

Hey guys,

I have a '15 V6 Mustang and had the stock 18" wheels on it. After searching for used wheels and tires on craigslist, I found a good deal for me. They were the 19" wheels from EcoBoost I believe. Anyways, after putting them on and driving the car for a day or so, the TPMS gave an error on dashboard "Tire Pressure Sensor Fault". After doing some research, I found out that tires are needed to be reprogrammed. So, I bought the TPSM Transmitter on Amazon https://www.amazon.com/gp/product/B001FKSNUI/ref=oh_aui_detailpage_o00_s00?ie=UTF8&psc=1 and followed the steps on this video . However, after holding the button on the transmitter to the sensor while in the correct mode, nothing happened.

So, could it be that I bought the tires/wheels without having sensors on them or they're not working? If so, would I be able to remove the working sensors from my original wheels and put them to the new ones I have?

The previous wheels I had, 235/50/18

The new ones I got, 255/40/19

How are you putting the car in training mode? My eperience was one way seemed to work but the TPMS wouldnt train, the other way actually worked.

Your post is timely. Up until 2 days ago I had never reset/retrained TPMS in any car. I bought that exact Motorcraft TPMS tool on Amazon and followed the exact same video on CJPP that you posted and I had no problems.

IMO: If you followed the CJPP instructions accurately, and tried more than once and things just didn't work, you have one of two things going on:

1. The battery in one or more TPMS sensors is dead. TPMS sensors do have a battery in them and they do go dead. I'm sure you could figure out how to open them and replace the battery but unless you have a tire mounting machine in your garage, you're better off just having the tire shop replace the whole TPMS sensor.

2. One or more of the wheels you bought is missing the TPMS sensor entirely. The seller screwed you, but as long as the wheels are solid (straight, not bent, etc) then consider it "still a good deal" and you get some new TPMS sensor.

Also IMO: If you really got a smoking deal on the wheels, spend another $100 or so and get all-new TPMS sensors put on/tires rebalanced at Discount Tire or the tire shop of your choice. That way you know everything is new, good to go, etc.

ps
The tire shop may agree to remove the TPMS sensors from your original wheels and put them on the new ones or not. If it were me, I'd just get new sensors for the new wheels, assuming that they are malfunctioning/missing.

The CJ video shows the correct way to enter training mode, there’s another method floating around which uses the toggle switches on cars equipped with them but that method didn’t work,so as long as you’re using the brake pedal and start button and you’re getting the dash message you should be correctly in training mode.

Sometimes you have to hold the button down on the training tool for up to 7 seconds (make sure the red LED on the tool comes on) next to the valve stem before it will recognize the wheel.

Did you see the TPMS sensors on your new wheels? How certain are you that the new wheels have them?

I agree: I did have to hold down the button on the training tool anywhere from 2-3 seconds to probably better than 5-6 seconds per wheel before getting the confirming horn beep. The procedure was very easy once I watched the CJPP video a couple of times.

I have a 2019. I put on new winter tyres. Didn't train the car for the new sensors, seems to automatically adapted and accurately too, to the actual PSI of the new tires. No caution messages so far (longest drive was 45 mins).

I just put my snow tires on 4 new PP1 wheels. The first 2 wheels are original factory 19" x 9.5" wheels I bought from Ford dealer #1 to put in the front of my 2018 GT PP1. I also purchased 2 TPMS sensors from that dealer at the same time. The second wheels are American Muscle 19" x 10" replica's. I then purchased 2 more TPMS sensors from Ford dealer #2.

What I learned is that the front TPMS sensors from dealer #1 utilized a different frequency than the rear TPMS sensors purchased from dealer #2. Basically, this set up didn't work. It wasn't until the difference in frequencies was discovered and 2 more TPMS sensor were purchased that matched the sensors from dealer #1 that the system worked properly.

The moral of the story is make sure the TPMS sensors you purchase are the right frequency for your car. Be careful because the original mistake was made by a Ford dealer who didn't understand that different Mustangs may require different frequencies for the TPMS sensors.

^^^ This is a good point. I don't know how the different frequency sensors work out, but the LMR website lists four types of sensors - TPMS35 (Ford sensor), TMPS39 (GT350), TPMS45 (GT350R), and M1180B (Ford Performance kit). When I bought wheels for my '18 EBPP from LMR last month, they really just needed to know whether I was buying for a GT350 or not. I ordered the TPMS35 kit, and the new sensors were trained before I left the Discount Tire parking lot.
