    2001 sts "service tire monitor"

    Hey all,

    New to this forum. I just picked up a 2001 STS. Yesterday the "service tire monitor" error showed up on the DIC. Does anyone know of a way to turn this system off? I religiously check my tire pressure weekly, so I am not really in need of the system, plus I hate having to cancel an error message every time I start my week old car!

    Thanks in advance.

    Looks like you'll have to take it to a dealer to check it out. It could be a sensor gone bad. It's a safety item, so it'll probably have to be checked with a scanner to be shut off.

    I had a similar problem with mt 2001 STS. Dealership reset the Tire Pressure Monitoring System using a magnet, took only a few seconds to complete. TPM can be turned off using the FEATURED PROGRAMMING section, however if the tire pressure goes below 24 PSI or above 38 PSI it will trigger a response on the DIC.

    Thanks for the input. Does anyone know if the magnet used to reset the system is anything special?? I have done some research and found that you simply hold the lock and unlock on the keyfob until you hear the horn beep. Then you have 1 minute per wheel to hold the magnet at the base of the valvestem, then the horn should beep again, signaling that that sensor has been reset. I used a normal magnet, but did not work.

    Any ideas??

    What we are talking about over here is the so called:
    Kent Moore Tire Pressure Tool - J41760.

    You can purchase it directly from Kent Moore Tools
    or e.g. via etoolcart.com

    Runs around $80.

    If you consider that the dealership charges you up to $40 for a reset and assuming that you will have to reset the monitors a couple of times over the years (in case that your tire dealer messes it up), maybe worth an investment.

    An article on ABN.com gives you a step by step guide how to reset the monitor.

    Good luck.

    If you're looking for a magnet that'll work, go to your local Saturn dealer and ask a tech for the round magnet that's used on the S series automatic trans. Usually they'll have a few floating around. Even if you have to buy one, they go for around $2-3.

    Re: 2001 sts "service tire monitor"

    I tried the "magnet" method by buying a Radio Shack set (5) of round 1 1/8" Ceramic magnets with about a 3/8" dia hole in them. Part #64-1888 for $2.99.

    I used the following procedure:

    1) Turned on ingnition (left key in ignition)
    2) Held down the Lock and Unlock buttons (at same time). A chirp from horn sounded
    3) Shut car door and put reciever (FOB) in my pocket
    4) Starting at the LF tire I placed the magnet over the valve stem (as close the wheel as I could get them). No luck... did not get a chirp...

    SO doing some more reading I found that the magnet had to be "Strong" I read where someone had purchased them from Home Depot. I had larger magnet at home. It was 1 3/4" dia with a 3/4" hole and 3/16" thick.. and tried again... still no luck... after days of frustration I broke one of the small magnets trying to drill it out larger to get closer to the sending unit of the valve stem.. still no luck getting the magnet closer.
    .. Then final sucess... I put the larger magnet at the base, the broken one (from Radio Shack) next, and the remaining 4 togther in a stack. That increase in magnetic power worked like it should. I did steps 1 thru 4 above and finally got the chirp... IT WORKED... then continued to RF, RR and finally LR and got a confirming two beeps at the end... Problem solved....

    SO GET STRONG MAGNETS... learn from my mistake..
