I switched wheels and noticed that after driving for some time all of the tpms sensors were reading except for one. I am not getting a tpms light and scanned the car with my Ktuner and didn’t see anything. Is there a way to reset the system or am I just unlucky and got a faulty one. I’ve driven maybe 10 miles so far.

Release the air in the tire under 27psi see if the low tire light comes on for that wheel.

if it comes on sensor is working and transmitting psi to the BCM and BCM isn’t telling the cluster the tire pressure or if the low tire light doesn’t comes on than either the BCM hasn’t memorized the tire sensor ID or the sensor itself is the issue.

Yeah I’m thinking it’s the sensor itself. I dropped the psi to like 25 and nothing came up so I drove a bit and the tpms light came on so I cleared it and it’s still the same.

Light came on, but still not showing psi on the cluster ?
after I dropped it the light didn’t come on so I filled it back up to 35 psi and then after driving for like 25-30 min it looked like this

then I cleared the code and it went back to how it was in the first picture in the thread.

Interesting that it flagged all tires, it should have only flagged the one (unless you lowered all tires under 27psi). What is it that is popping up that you are clearing ? You should not have to clear anything for the warnings to clear. All you need is the tire pressure to be above 27psi (have a working sensor obviously lol) and drive the car for at minimum 40 sec above 15mph and it should go away. If not a key cycle and a quick drive should correct it. Where are the sensors from? Are they OEM?

42753-T3R-A04 From ebay. They look the same as the ones PRL sells on their site.

When the light came on and all the tires looked like that it was already after a good amount of driving and was totally random. I didn't have my laptop with me but tunerview allows you to check and read codes from the phone so I checked and it didn't pop with any codes at all so I just hit clear. And after hitting clear it just went back to how it was before with just the one tire at the front left not reading.

I haven’t tried using ktuner to read codes but I’m pretty sure it only reads check engine light codes, you would need a scanner that could read all the modules in the car to access TPMS stuff

Ah that would make sense why I couldn't see it. Ill get my hands on a better scanner but in the meantime I contacted the seller to see if I can get an extra one sent. Will update once I fix it.
