They're molded in. There was a member at one time who was replacing batteries, but I think it's more trouble then it's worth.Stupid question but are the batteries replaceable or are they molded ni
First of all, make sure someone didn't replace the valve stem cap with a part that will interfere with the transmission of the data from the sensor. The valve stem cap is made of aluminum and the valve core is nickel-plated to resist corrosion. The end of the stem serves as the sensor’s antenna.I am new to this. I have an 01 conv. I am now getting a lf tire sensor low on the dash. What is my next move. Tire pressure is 30psi on all tires.
