TPMS external interference

ChuckBimmer · 06-30-2008, 10:24 PM

I just installed the laser interceptor to my car over the weekend. This morning driving to work I got a TPMS error message "TPMS external interference." Is the laser interceptor causing this problem or is it something else? The tires are ok from a visual inspection. I reset the TPMS but it the error message came back on the way home from work. Thanks in advance.

PS I am reposting this in the wheels section because I hope to get an answer.

I don't know how a laser interceptor works, but if you can shut if off, I think a reasonable test would be to...

1. Turn off laser interceptor
2. Reset TPMS
3. Drive

If the error doesn't come back...

4. Turn on laser interceptor
5. Drive

...rinse & repeat.

I read that the TPMS broadcast at 44mhz...some sort of hertz anyway so you'll have to see what the two are doing.

Tried this today on the way to work and the error did not return. Then on the way home I turned on the laser interceptor and the error did not return?! I still have no answer...damn.

Sorry it's NOT 44MHz, it's actually 433MHz.

To original poster, sorry can't help you with your problem.

Sorry to bring back an old thread, but I just started receiving this error. Warning comes up, "TPM ext. interference".

Yea I'm having this same problem now it seems to come and go the only things I've installed recently was my p3 vent gauge any thoughts..?

I'm getting the same error it comes and goes anyone have a solution or we need to change some module?

I get it occassionally as well. It seems to be something the TPMS is picking up in the atmosphere, but still makes me think the internal sensor is bad. It started happening for me after a new set of tires were install. The installer was very careful with the TPMS.

I had the same problem.. it turned out my HID ballast (EuroTek) for the fogs were causing the problem.

bigdaddycane · 10-11-2011, 09:47 PM

Interesting, I have HID fogs as well and this pretty much started (intermittantly) after I installed them.

Did you find a fix or just live with it?
