Tpms wtf

[NHWK05]

So i am driving my jeep today and the tire pressure light starts to flash and i get a bing bing noise.

My jeep does not have the advanced TPMS system that tells you what each tire has for pressure etc. Its just the basic setup i guess that tells you if its low.

So i assume a tire has low pressure.
Besides going out and checking tires with a gauge and filling each one is there any way to find out what tire is low from in the jeep? i could not find anything in the cluster information center.

Also could it be the spare or is that not included in the basic system?

Finally will the bing and light (it goes out after a min or two) will it stop coming on every time i start up and once in a while while i am driving if i just add air to all the tires to the right pressure?

if you dont have the advanced system...you have to check each one. If they are fine...check the spare. That light will stay on and you will get the warning untill you fix the problem

add the right pressure and you will be golden....

[NHWK05]

OK, But all i have to do is fill up the tires to the right pressure on the door sticker and it will go off on its own?

Saw Edit, Thanks.

[Scottina06]

yeah.....as soon as the tire reached the normal opertaing range or above 29 psi if i remember correctly

[NHWK05]

Ok, cool, i will check them all tomorrow.

[mjl2610]

I fill mine to 35 all around. Some think its a bit high but i think its alright.

[Megatron]

Yeah mine is a bit high also, around 34.

check em tomorrow kyle, you should be fine

[NHWK05]

Will do, Thanks guys, I normally run 32 psi but i might go a bit higher for getter MPGs and cause i dont give a fawk about the stupid fortera hl's.

I have 2 dead/malfunctioning TPMS sensors, YAY, and its could cost about $200+ to fix it after labor. Fawk that noise, he cleared the codes for now.

I have the basic system that does not tell what tire has what pressure, it just says "hey there is an issue" So there is no way of knowing where each bad sensor is. it said sensor 1 and 2 are bad, that could be any where on the jeep or the spare tire.

the only way to tell is to actually dismount each tire and check the sensors and the new sensors need to be "learned" or programmed before install.

It is also illegal for the dealership to deactivate the system. If i could get my hands on a scan tool and deactivate it myself and put in regular valve stems if i wanted.

it will prolly cost in excess of $200 to get it fixed, he cleared teh code and i am gonna leave it for now as i have better things to spend $200 on.

[Scottina06]

weird that 2 would fail at the same time huh?

[NHWK05]

Thats what i thought, but i know the tech and i looked at the scanner myself.

[Scottina06]

I know you can get the sensors cheaper...but its gonna be a pain to find which one it is.

[NHWK05]

Thats what i figure, try justforjeeps.com, ebay, jeepsareus.com and then see if i can bring them to the dealership and have them install them when i get the $.

[Scottina06]

I would try LKQ on ebay...they are very good about listing what tpms goes with what year etc. Any tire shop can swap them for ya as so many vehicles have this now. I would call ahead to make sure though. They also wont cost as much as the dealer

[NHWK05]

Oh, good, i did not know anyone could swap them. Even if it needs programming?

The problem is still that i know its the 1 and 2 sensors but i dont know which wheel has what sensor as its not able to tell me that.

[Scottina06]

yes...any tire dealer that handles TPMS can do what you need

[NHWK05]

Quickly looking i found these, but i need to verify if they will work in an 05 and if they are the right kind of sensor for my system but it gives me a good idea of pricing.

Thanks scott, i will see what tire shops charge to fix it.

[Scottina06]

Kyle-I just had a new wheel put on the rear and the runflat goodyear dealer didnt charge me a thing. But that was just the install kit and swiching it over.

[NHWK05]

Oh Cool, I am not going to fix this until i get Ducks Unlimited's stock 18s in the fall and my new tires but i will prolly buy the sensors soon.

BTW, thanks for the LKQ idea, $75 for 4 or $50 each, i think i will buy from LKQ.

[Scottina06]

lkq warranties theer items too is what i like. they are sending me a new 08 hid headlight becasue of condensation in the one I bought from them in 8/08

[NHWK05]

Sweet, thats really rare for an ebay store, usually its a short term warranty.

[mjl2610]

Discount tire had replaced my new sensor i brought, balanced and filled the tire on my moms wj for 17. You still have the issue of not knowing which one(s) are bad.

[NHWK05]

If i buy the ones from LKQ on Ebay its a set of 4 and i will replace all for and then if its the spare thats bad process of elimination for finding a good one.
