I noted a pretty good price $47.46...it that an actual OEM Ford price? Also I noted one part for both 03-04 and 05-06 though ford lists with seperate with different P/N. Are they interchangable? Thanks.

 

02-04 is listed as black PN 4L2Z1A150BA list $79.94 ea

08/02/04 to 08/02/06 listed as blue PN 5L1Z1A150AA List $79.82 ea

my sell price is about the same. and no they are not interchangable that I know of, if they were Ford would only give me one part number. well they should anyway. lol

My expy didn't come with TPMS. I've already bought the sensors but does anyone know what the other part # is for the part that I need that goes in the rear left hand side of the vehicle to make the vehicle acknowledge the sensors?

 

Hey all,
Not sure if it is the same with the older TPMS sensors but with the newer ones, when they send their signal to the vehicle they report the psi of each tire. I've been told that this info can be read using an IDS scanner.
What I would like to do is find out what frequency the sensors transmit on so I can build a small handheld receiver that would alow me to view the presure of each tire. We have an 09 Escape Hybrid Limited, any information would be extremely appreciated.

 

TPMS valve sensors operate at either 315 MHz or 433.92 MHz. I don't know which of the two is the one Ford uses. But in order to read the sensors on demand, the sensors have to be activated by sending a 125 kHz LF signal (either continuous wave or modulated.)

I found this information on this site that sells the diagnostic tool for TPMS.
TPMS Dealer Tool & TPMS Dealer Tools from Bartec USA
It's under the section header, "How do TPMS service tools work?"

 

I'm pretty sure they work at 433 MHz. Also, just so everyone knows, I dont think you can add fix a flat or any other tire sealant while using the TPMS sensors. I've done this and now have a bad sensor because of it.

 

Used your instructions to rest our 08 GT/CS


Thanks again !

 

Can I use any old car speaker magnet to do the Re-Learn procedure?

 

Which vehicle?

You may want to watch this video, magnets were used at some point but depending on model year and make, it may be through a couple of different methods.

 

2004 Lincoln Navigator

 

Ok, that uses the old TPMS1 black sensor. Check the video and try on yours, two of the three methods are free to try, letting air out or the magnet. Any old magnet will work, as long as it's strong enough. I use a strong magnet out of a hard drive when doing mine. If none of those methods work, then perhaps you need that little remote. Did you just replace your sensors? They do have a life expectancy of about 10 years before the battery runs out, so if yours are still the original ones it may the the reason why you're having issues.

 

I used to 22 inches wheels and that messed up my front end. I removed those wheels and I installed the OEM wheels. When I changed the tires one of the sensors is broken. I bought a new one. I haven't mounted yet, but I'm sure when I mount it I would need to do the Re-learn procedure right?

 

Yeah, when installing a new sensor you need to do the relearning procedure. Hopefully the new sensor still responds to the magnet or if it's an aftermarket one, it might respond to letting air pressure out. If it's a new OEM then as he says in the video, many of those has been updated and no longer responds to the magnet, but require that little remote tool he had, it's about 38 bucks on Amazon if it turns out that you need it.

 

How Frequently this procedure needs to be done? Here is the sensor I bought

Basically you only need to do it when replacing a TPMS sensor. On trucks that has different air pressure front and back, or some sort of display that actually shows the PSI on each tire and gives warnings to a specific tire, you need to relearn them at every tire rotation. On Expy, and I suppose Navigators of the 2nd gen, it only says "Low tire pressure", and doesn't specify which tire. These trucks also has the same pressure in front and back, so it's not really necessary to retrain them when rotating the tires.
