In this video i ll show you how to replace toyota lexus tire pressure monitoring sensor tpms battery.
Tpms sensor battery dead.
There was worry and paranoia from all sides.
If tmps battery is low then at the startup of vehicl.
Tpms sensors are no different.
If a battery is dead you have to replace the sensor.
Dead sensors cause other problems too the initial expectation was that the sensor s batteries should last 5 to 6 years and some did fail within that window some failed even sooner.
On most applications the battery is sealed inside the tpms sensor and cannot be replaced separately.
Well after getting the battery replaced and after about 10 more miles of driving the tpms light came on again.
Some tpms sensors use a 1 250 volt nickel metal hydride battery.
All sorts of problems can arise from a dying tpms sensor battery.
Dead sensors cause other problems too during the initial tpms phase in many warned about what sounded like an impending crisis.
It appears that the left rear sensor is not working most likely due to an improper repair on the tire.
The battery is encased in the sensor s molded plastic housing.
But for the most part the batteries have exceeded expectations.
What can we do about it.
All the obvious stuff will turn on the indicator light but i ve seen all sorts of crazy stuff that ended up being caused by a dying sensor battery.
Some sensors even transmit the state of the battery.
It is within reason that if one sensor fails due to the battery the others should be replaced.
A battery that is running low on or is depleted requires the replacement of the entire tpms sensor assembly.
