reprogram TPMS from 5 to 4 wheels?

I purchased a used 09 Wrangler for my wife about a month ago off of a good friend of mine who is a salesman at the local Toyota Dealer. He gave us a great deal on it, we payed what they had into the Jeep. As we were going over thier used car service report 2 items on the bill scared me. The items were 1 aluminium wheel and 1 new Goodyear tire. Now my first thought was that the previous owner hit something hard enough to damage the wheel and tire. Well thats wasn't the case, the used car department told me someone stole the full size spare when it was on their lot so they replaced it with a used wheel and new tire. My first mod was a set of Jeep wheel locks. This past weekend the wife went on a trip and called me to tell me that the TPMS light is on. She pulled over and no tires were low on air. When she got home I checked all 5 tires and all had 35psi. When I turn on the ignition the TPMS light flashes for 75 sec then stays on. I am wondering if this is indicating the missing sensor in the full size spare? Do any Jeep Techs know if I can use my Snapon TPMS 3 unit to only program 4 wheels instead of 5? I dont want to go back and beat up my buddy for a sensor if I can just reprogram the system. Sorry post is so long, Thanks in advance,

The system does not read the spare.

A low spare tire will not cause the “Tire Pressure Monitoring Telltale Light” to illuminate or the chime to sound.

The chime and the flashing indicates a faulty sensor or interference. another thing to keep in mind is that the sensors have batteries that are not user replaceable. When the battery dies, it will set off the system. Deflating and inflating your tires for off road use will cause the battery to die early.

The “Tire Pressure Monitoring Telltale Light” will flash
on and off for 75 seconds, and will remain on solid when
a system fault is detected. The system fault will also
sound a chime. If the ignition key is cycled, this sequence
will repeat, providing the system fault still exists. A
system fault can occur by any of the following scenarios:
1. Jamming due to electronic devices or driving next to
facilities emitting the same Radio Frequencies as the TPM
sensors.
2. Installing some form of aftermarket window tinting
that affects radio wave signals.
3. Lots of snow or ice around the wheels or wheel
housings.
4. Using tire chains on the vehicle.
5. Using wheels/tires not equipped with TPM sensors.

The computer does not read the sensor in the spare.

Bah Daggo beat me to it and with a better answer.

Thanks guys, I did read that when I did a search of the forum but was unclear if a missing sensor would cause the light to flash and stay on. I guess I got a problem with one of the 4 sensors.

Should be no problem I would imagine to have replaced or fixed by the dealer since the jeep is only about a month old.

If the missing sensor was on the road it would cause the warning light to come on. These can things can be fragile. Even window tint can affect them as stated by the above.

The dealer broke one adding air to a tire in my wife's Liberty. They tried to charge me for it. When I asked why he was adding air, I was told it was part of the oil change service. I asked what PSI he set it to. They told me that all the tires were low and he inflated them to 35.

That's when I blasted them. I had just rotated the tires and set them all to 33 PSI, which is what is on the door sticker. Needless to say, I didn't have to pay for the new module.

How early??

Will using a Procal, or the like, to set tire pressure to 0 while aired down prevent this??

I think about one and a half TPMS sensors will pay for a Procal!

Does the spare have a TPMS sensor? Just curious as I am replacing my wheels and tires and plan on removing the sensors from the wheels on my current set. Thanks.

Using the Procal will only affect the alarm aspects of the system. The batteries in the sensors will eventually die either way.

You can turn off the light/chime altogether by setting the TPMS to zero. Or, if you're the type who wants to use the sensors "because you paid for em", you can set the threshold to 20, or 15, or whatever PSI so that they'll still work, but not at the factory-set level.
