What is the best aftermarket TPM sensor? I replaced all 5 about 2 years ago on my 2006 XJ8L. The only one that didn't work right was the spare. I thought it was because It had not been on the car and now that it is on the ground the light is on and won't go out. I think it may be because it is a different (different manufacturer) sensor from the other four! I can't remember the name of the ones that are working. I bought one that were recommended in this forum. I hope you can help me once more.. Thank you. Jackie

 

I posted my TPMS issue on the forum, that was similar to yours with trunk not reading. All sensors were genuine. Search the forum for my post, It should help.
