It is possible to bypass the TPMS system (In techstream)? (1 Viewer)

Hello, wondering if this is possible.

We use our LX so much offroad, and are constantly changing tire pressures etc all the time. (IE airing down for several hundred kms at a time), then airing back up for road travel - It's annoying to have the TMPS system act up every time we air down

NOTE, I'm anal and manually check the tires constantly anyway, especially prior to highway travel etc. I do this on all my vehicles.

Anyway, really would love to simply bypass this system completely, so that the computer doesn't throw an error code all the time.

OR is it possible to lower the error light pressure threshold so that we can see the lower pressures, just not the big warnings?

Has anyone done this successfully?

There isn’t progress on an electronic bypass that I’ve seen. It comes up every couple years. There is a bypass for the tundra and Tacoma, but they use a different system.

You can ‘fool it’, by putting the tpms sensors in a pressurized can and storing the can in the vehicle. I’m sure an internet search will reward you with a variety of different ways to implement this.

Ha! I actually thought of doing that. But kind of forgot they'd actually need to be in a pressurized environment. Wondering if its really worth the trouble. Probably easier to just have the lights bark at me every time I air down lol

Probably not going to find a true easy bypass.

I just look at the light when aired down. If my wife calls me and says the low tire light is on while she is at the mall it was worth it.

The other problem is tire shops may not service tires if your car requires functioning tpms.

So you have to be able to break the bead and pull the sensors out manually.

And possibly get stuck with having five tpms installed if you need to replace a flat or a tire while on a road trip.

It can be overridden with CANBUS spoofing, but custom coding the CANBUS is expensive.

to resurrect and offer a potential solution, I was able to program my new Toyota tpms sensor with my new spare using MaxiTPMS TS508WF. It read all the sensors (new and old) without issue and I was able to eliminate the TPMs light via the obd2 port using this tool. So far (200 miles), the light is off and all pressures are reflecting accurately. HTH
