My tpms info say pass side tires are both ok but both driver side have no info. How do I know if both driver side sensors are really the issue since I don’t know if tires were rotated and positions are right/wrong?
I could add air to pass tire and see if display changes?
I just got car.
Any tire shop will have a scan tool and can tell you if the sensors are working .

Do you have an orange tpms warning illuminated?

Yes, tpms dash light. DIC says both driver side tires have no info
On my cars, when one sensor goes out, I still get a reading on the others. When I had problems with the Acura, there was no info on any of the tires. It was a problem of the unit in the trunk. So my guess would be the tire sensors not the system.
No offense, but are you sure the sensors are present?
If some TPMS sensors are not working it is a good bet that the others won’t be far behind. I find that they need to be replaced about every 10 years, maybe earlier.
My dads car. He has 4 newer (2 yrs) tires. I’d think shop would have mentioned missing sensors.
I doubt anyone would have gone to the effort of taking them out and putting in a $2 valve stem but wh knows, there are Penney pinchers around. My experience though is that some seem to last a long time and others not, with no rhyme or reason. It costs me $80 to have them replaced so I only do it when they go out. Some never have failed. I have no problem if someone wants to pay an extra $300 for new sensors when they get tires but no guarantee that will take care of it.
Yup!
One of my old college friends is the cheapest person I have ever met. When his dishwasher died, he opted to not have a new one installed. I mentioned to him that he would actually use a LOT more hot water if he washes his dishes by hand, and his response was, “Not for me. I wash them in cold water”. Trust me… nobody will eat in his home because of his “cost saving” measures.
He drives less than 1,000 miles per year in solely low-speed short hops, and despite my warnings about the need to change his oil at least once a year, he insisted that “I don’t need to change it because it looks clean”. After 6 years of that type of “cost-saving” he had a major repair bill because his engine was so clogged with sludge.

Put it on a lift and move the tires to the other side. Does the same side show nothing or the same tires?
Well, unless I missed it, you haven’t told us WTH vehicle it is… 
Different vehicles do TPMS differently…
If you don’t use the synch tool to relearn the position of the tires your display will not change. You can’t just swap wheels and assume the car knows where they are.
Yes, what Dave says. If anybody here doesn’t have a synch tool for their car, they aren’t that expensive. $30 on Amazon? Just make sure you get one that works with your car.
I drive a 2017 Chevy Volt and the procedure is laid out in the owners manual. Works good, lasts a long time!
Depends on the car. Not all use a sync tool.
I got a 2009 equinox last fall. Wheel sensors did not match DIC info. You can do a manual reset using DIC interface.
New car is 2011 chrys T&C.
I’ve replaced sensors YEARS apart. I just replace when needed.
I get free tire rotation so I just have a cup of coffee while the shop does it. Those tires are getting heavy.
Check your pressures in all 4. The sensors are not cheap and you need the correct ones for your car model and year, some after market wont do the job. 2018 is my vehicle had to replace them last year, batteries are not replace able. Need a tire shop to do the work unless you are handy.
