TPMS> ITM Uni-Sensors ’97, ’98, ’99 Owners Chime In
Getting ready to put on some new tires >“meats”< on the ride and going to swap out the TPMS’s while the meats are off the wheels. As I have a 1999, finding fresh (batteries) OEM TPMS’s is very difficult. Additionally, I do not want to swap out the receiver, TPMS’s and fobs as I do enjoy the features the ’99 Fobs.
I’m looking at a set of ITM Uni-Sensors and as I understand, you can NOT use the standard DIC tire training method (with large magnet) to train these ITM Uni-Sensors to each wheel.
Are there any 1997, 1998 or 1999 owners on the CF that installed these ITM Uni-Sensors in their wheels?
Did the tire shop “clone” your replacement sensors from your original sensors?
Did the tire shop use a magnet to activate your original sensors to capture the RF ID number to use and program into the ITM Uni-Sensors?
If you could post up your experience with ITM Uni-Sensors, it would be very helpful.
FYI> I have 18inch wheels on all four corners (Ace Alloy Slick wheels) and will be putting on the Continental Tires ExtremeContact DW’s, 265/35/18 up front and 295/35/18 and the back.

Hello, As I have received a PM on these ITM Sensors, posting up my experience;

I do have the ITM sensors on my ride and they work perfectly!!!. Although I have these ITM's installed on all 4 wheels the training of these sensors is different than the OEM sensors.

The sensor difference is as follows;
The OEM sensor needs a magnet placed next to the valve stem to activate or train to the car/wheel position.
The ITM sensor uses "rapid" air pressure change to train to the car/wheel position, (NOTE the magnet will not work with the ITM sensor).

During my ITM training, I aired up the tires to 35 psi and activated the training in the DIC then rapidly deflated each tire after the horn beep. when all was said and done, my tires had about 15psi left in each tire which then was inflated to correct pressure.

One more comment, the car's learning mode does not allow for a "slow wheel learning" process, basically you need to move quickly to the next tire after the horn beep.

As I weigh 2 bills plus...I could not move around the car quick enough to deflate all 4 tires to complete the learning process and what I did was put the car up on tri-pods, removed all 4 wheels and tires, laid them in a row next to the car, activated learning process, LF tire, beep> RF tire beep>RR tire beep>
then reinstalled the wheels and tires, all is good now.

hope this helps.

Here is the questions that I PM'd to Kevin,

tabbruzz

I have the ITM sensors. Releasing air pressure allows the sensors to sync. I was able to do all 4 tires on the first shot but I moved quickly...

Droberts

Thanks tabbruzz,

Would you know if the system could learn a combination of OEM and ITM sensors?

I would look into the upgrade to newer parts. I have a 97 and have been looking around. You can find a newer receiver for $50 on eBay. Then 2 key fobs are $25 on amazon . Then tpms are like $30 a piece . You can do the whole change over $200 if you shop smart.

tabbruzz

I am not sure about that. I think so. I know I my car did sync to my itm and OEM but I currently use 4 itm right now.

Droberts

OK, thanks. I'll give it a try and post the outcome.

Droberts

Thanks, are the key fobs necessary to do the TPMS upgrade?

Bought these off ebay and have no issues with them

I successfully learned three OEM and one ITM-Uni sensors to the TPMS system. I used a magnet to learn the OEM and rapid tire deflation to learn the ITM and they all beeped confirmation.

That's great news that a mixed configuration of wheel sensors will work as this now provides options for someone faced with replacing the sensors!
