the system keeps registering an alarm on left front wheel then starts working again only on rough roads

 

year make model
tpms not the abs correct?
when the tpm light comes on; is the tpm light flashing or on solid

 

it flashs

 

it flashes

 

2007 Silverado 2500 z71

 

flashing means there is a system failure as opposed to a low pressure reading. Its a wireless system. have all the tpm sensors registered...any that will not register need to be replaced.

 

thanks

 

I bought quite cheap sensonrs on aliexpress and they works on my chevy suburban 2009. I used these, ordered 7 pieces, one was wrong (could not be learned) and one shows different number that it should. but now I am satisfied. https://www.aliexpress.com/item/Car-...27424c4dhCoBvc
It cost $13.64 when I bought them.
