Change Tire sensor & service require warning

Is the car still under warranty. If so take it to the dealer. You could also try to unhook the battery and see if it resets the computer. Sounds like that might be the problem. Not sure but thats what I would do.

 

If I am not mistaken, you might have to check the dealer to "program" it or something.... since you have new TPMS. But I'm not 100% on that.

 

Yeah you might have to program them for our cars. When I got my rims I was trying to get an extra set of sensors so I could just swap out my wheels when wanted without getting that message. I was told that the new sensors would have to be programmed and that I couldnt have 2 sets programmed at the same time. I was told this by the discount tire guy, but Im not too sure that he actually knew what he was talking about or if he was just telling me what he thought.

 

yeah pretty sure they gotta be set by the dealer----when you take your car and change the tires, they take a TPMS rebuild kit, (basically taking out the sensor in yours, and putting it into a larger or smaller casing, to fit the size rims/tires you changed-----completely new ones they'll have to set for you.

 

Yeah I'm getting new tires and rims monday and decided on not getting the rebuild kits. Im starting to think if I should.

 

Has anybody had their TPMS light come on when it's very cold and then go off after driving a while?

this problem happens to me every once in a while, just figured I'd ask everyone else.

 

Your tire pressure is affected by the change in air temperature. After all the air inside your tire is just compressed air that you breathe shoved through a valve stem into the tire at high pressure. Other than that when the tire pressure changes as little as 3psi the TPMS light will go on and prompt you to check your tire pressure.

As for the requirement to reprogram your TPMS? Yes, at each tire rotation, flat repair, tire replacement, or summer/winter wheel swap, you will need to retrain the TPM sensors. The cars computer cannot remember the tire pressure sensor IDs of the previous set. The system just isn't designed that way, and for good reason, it was never necessary to have two sets programmed. I'll check the actual programming procedures in my manuals on Monday for everyone.

 

No, the Tire pressure service light comes up only when the system either doesn't recognize pressure sensor IDs or the system itself has failed (the latter which is VERY rare). As far as knowing when to rotate and align the vehicle? I would suggest just checking the alignment EVERY 6 months, and just get the tires rotated with each oil change or alignment.

 

Damn looks like I do have to get them after all. Oh well it was like 40 bucks extra at discount. No big deal.

 

Simplified this is called Charles Law. If you want to look it up you can but it may look greek the way some places describe it. Simply put though as temperature increases volume increases. So your tires are cold with a low volume, TPMS kicks in, drive for a little bit the tires heat up and again so does the volume, TPMS goes out. Just some food for thought.

 

I'll have to check the Mitsubishi programming specs.
