Hello,

I want to thank everyone that contributed some ideas to the TPS problem of my 2015 XJL. Turns out it was not the TPS sensors in the tires or the modules that they connect to. It was the front intermediate connector had been compromised and was corroded. C11 is the connector that connects the front TPS receiver antennas to the front interface/ engine fuse box. It appears the connector was not fully seated and water had been seeping into it for some period of time. Once the contacts were scrubbed, sanded, scrapped clean, and sprayed with some contact cleaner and Deoxit, the warning has not appeared after a few days of driving! Not sure if there is a way to view any information relative to the state of the tire pressure in the instrument cluster but at least I don't have that same warning on the dash whenever I start the car.

See photo below. Thanks again! Dave

 

Good job!
BUT don't leave out "The Rest Of The Story" as they say?
How did you find it?

That's great news - at long last!
It might be helpful if you can merge this stand-alone post with the one that was going, so that it is continuous from beginning to end; including the cause, solution and closure.

 

Thank you for reporting the fix!

My wife once owned an Subaru Outback that probably went back to the dealership 15 times to fix a TPMS snag...It never got fixed! In the end I put a mall piece of black electrical tape over the caption on the dash!

Thanks again and happy motoring!

Hi Guys, I'll write it up with some diagrams and more info in a bit. Thanks for the idea Clubairth!

 

Hey you deserved a break on this repair! You can do all the right things and STILL not find it.

Great catch, those little green fuzzies in there cause all sorts of issues. Nice to catch something like that so you know it's fixed.

 

I was an electronics technician in my previous life. Reading schematics and wiring diagrams was daily activity and I just never give up until I fix the problem!

 

Then you picked the right car!
Congratulations on the fix, that is great diagnostic work.
