Tire Stem Valves

My spare was stolen a few months back and to save money, i bought a used tire with rim. However, my tire pressure warning light stays on (blinking). The dealer told me I needed a new tire stem valve containing the sensor for the spare and it needed to be programmed. Total cost quoted is $207 plus tax.

Can the tire pressure warning sensor be deactivated to stop the blinking warning light on my dash? Or do I have to spend $207?

The only way i know of to deactivate it is pull out the gauge cluster and unsolder the LED that lights of the tmps light. If u dont want to do that your going to have to buy the sensor. Try finding a used one since 200 is pretty pricey.

 

haha that does work also.

 

I'm confused, if there is no tire sensor in the spare, why woould the tire pressure light keep blinking? Can't it just be replaced with a "normal" valve stem?

 

old model 2nd gens had the tpms in the spare tire. i don't think the 09 and 10 have the tpms in the spare.

 

I would think the dealer could reprogram the TPMS for only the four wheels, but maybe they don't have a manual for that.

 

my 2010 tacoma have the TPMS in the spare
Dealer say if the light come on you need check all five tire for presser.
Yes there on on the spare for tire rotation.

 

i wouldn't exactly use my spare for anything other than a spare. it's full size, but the rim is a spare rim. no rotating the spare for me. i'm still certain mine does not have a tpms.

 

The dealer won't alter safety systems. It came with 5 sensors, so the computer looks for 5 signals. Each sensor is coded and needs to be entered by scan tool.

 

This is a good idea but they would still have to break down the remaining four tires to get the codes. From everything I have read about the system, including the online sm on ncttora, the tpms ecu only stores the numbers, up to 5. It doesn't tell you which one is which. The cost to this would probably add up to getting a new one unless something has changed.

If you have an 2006, you can ground out the system fairly easily. It is documented over at TN. http://www.toyotanation.com/forum/showthread.php?t=326748

There was also a guy w/ a 2006 who spliced an inline fuse so he could turn it off or on depending on what set of tires he used (winter or summer). The pics disappeared on that one for he sold the truck & deleted them off photobucket.

This was only a fix that worked on 2006s.
I opted not to do anything when I swapped tires out (summer/winter) & only trigger a light after being out of range for a certain period of time. I do have a sensor in the spare fwiw.

 

Actually...the tires don't need to be broken down to get the codes. America's Tire and Les Schwab were able to get the codes from each valve with their scan tool. The problem I had (2 weeks ago) was their device not being able to load the ID #'s into the ecu of the truck. After not wanting to pay the stealership $125 to program them, the third time was a charm for America's Tire to get it written to the ecu. They updated their scan tool and BAM all sensors are good to go and NO light.

I also believe the system can store more than 5 codes, as people have winter wheels with the sensors and it's able to read all. I'm not positive though as I only have one set.

 

Or you could save yourself 200$ and just let the light stay on.
That's what I do

 

Good info on not having to break them down.
The Service Manual from NCTTORA stated only 5 codes. I run a winter tire set on my stock oem steel rims/sensors. My summer alloys do not have sensors except for my spare. I know members here who have sets in both & have to get them reprogrammed. I don't throw a light unless the system stops communicating with my stored sensors. It doesn't throw a light at all unless I head out of town but resets once back home overnight. I use a tacomaworld business card to cover the light til then.

 

My '08 spare was plain black, not the silver stylized. It had a tpms sensor. I have extra stock rims for sale, if you want to put your lazy tire into the rotation.

You should read more of Simon's mom's post. She knows her sensors. The scan tool only tells you what's entered. NOT where it's mounted. You have a 1 in 5 chance of changing the right entry without having the old sensor in hand.

 

i will sell you a tpms for 40$+ the shippin they go for a about $110 normaly
