techstream tpms

Does the following show tpms 2-5 no good?

 

Somethings is obviously wrong, but I'm not sure it si your TPMS sensors. I get an N/A when my sensors go bad.

 

I think it means when tire pressure gets to 23 - 22 or lower the light on the dash will come on.
The 45 on the first one may be maximum pressure before the dash light comes on.

 

I'd say they're bad. Those 4 sensors that read negative psi also read negative temps in the tire, while the one tire has 42psi and 45 degrees. I've seen them read 0 psi when the tire was at 35psi. Usually our tire sensor tool won't even read them when they're bad.

Unless you're planning on replacing them yourself, I'd just go to a good tire shop and let them check it with their tpms tool to confirm. Our shop doesn't charge anything to check them if the light is flashing.

 

I would say they have a malfunction. It should be showing pressure... Do you have the TPMS Light on or blinking?
