does any one know if these tps battreies have a shelf life. just had one replaced with a 09 date on the box and worked for about an hour
Thats the only one they had at the time. they are going to replace it again under warranty.
See if they'll let you keep the bad one. Replace the battery and keep it for a spare.
Answer to what? Bear with me as I just woke up and not at my best....well, I'm never at my best but what the heck, eh? I am the best at being me, though.
This is a spare that would require the ECU to be reprogrammed in order to use. Much easier to replace the batteries in the TPMs that the system already recognises.
