Hi, My 2006 dts, service tire monitor system shows on my dash. I went to a tire shop, the mechanic put a meter on each tire and said the sensor battery on one tire reads low , then lowered al tire pressures to 20 psi then put 30psi in each tire and the warning message on the dash went away. after 30mins of driving the warning is back on my dash, any info, Thanks Tony.

If you've never replaced the tire sensors and had the car since new then they are long overdue and I'm surprised they have lasted this long. If you weren't the original owner then perhaps over time prior owners have replaced them as they went dead. They are little sealed radio transmitter units mounted inside and are part of the valve stem. They have internal batteries that simply go dead over time and the batteries aren't replaceable as the units are totally sealed. Any good tire shop can replace them for you at about $70-$100 each including the labor - maybe cheaper if you shop around but they have to take each tire off the car and unmount it from the rim to replace each sensor. If the others are still good then just get them to replace the one that is dying. You can actually buy them on eBay and then have a shop replace them. The lowering and then increasing tire pressure while the car's display is in "Relearn Tire Sensor" mode - accessed through the dash buttons - is how you get the system to recognize the sensors. Most tire shops also have a tool they can use to bypass the air pressure changing procedure when they replace them.

thanks Thlellmer, As I went driving the next day the tire warning went away,and has not returned in over a week. I have another question, the tire pressure is at 30 psi I would like to raise the pressure to 33psi, do I have to add pressure in the sequance of right front, right rear, left rear then left front. Thanks Tony.

No, you can add air in any sequence you want to...
You only need to do the Left front, right front, right rear, left rear when you are RELEARNING the tire pressure sensors...
The correct sequence is Left Front... Right front... Right Rear... Left Rear.
Thanks Superjim, for the additinal info , Tony.
