Mucar TP90 TPMS tool | Owner’s Review

Mucar TP90 is one of the most affordable tools I could find to help me deal with TPMS light issues. While it costs the same as a better engine code reader, it can capture frequencies from car keys and TPMS sensors which helped me solve my problem. By the way, it even works as an engine code reader!

I solved the TPMS light

I got it to fix the TPMS light for my friend’s Corolla. Each Tire Pressure Monitoring System sensor has a unique ID number so your TPMS module now, which wheel is transmitting data and if it is even a sensor from your car.

When you change wheels or sensors, there is a difference between the ID numbers on your sensors and the ID numbers in your TPMS module causing your TPMS system not to work and the TPMS light ON.

First I read TPMS sensor IDs

I put TP90 close to the TPMS sensor and hit the signal button.

Continue to get ID from all 4 wheels, or even all 5 if you have a spare as well.

I had trouble writing IDs to my control module

I tried all options but I had a hard time writing sensor IDs to the control module. The tool should be able to do it, it even can do a comparison of IDs by OBD & signal.

It means, that after finding TPMS IDs from the signal, you can plug it into the OBD2 port.

And compare sensor IDs from signal & OBD to see if they match. Here is a photo after fixing the problem:

Sensor’s match but I had to use another tool for writing IDs in my TPMS control module. However, I think that is the problem with this particular car, as it should work just with TP90 without using other tools.

For writing IDs, I used Mucar V07.

Conclusion: Testing Mucar TP90

Considering the price I still recommend it even though I had some problems writing sensor numbers but this is how it goes in OBD-II scanners.

Some scanners will simply not work correctly for certain models or option combinations.

But for the money I spend, I got a great tool to at least find out sensor ID numbers without me having to remove tires to read these IDs on sensors directly.
