okay so i turned on my key and this light came on above the headlight light. i think its the tpms or whatever, so i took out my pressure measuring tool and then i thought to my self how the eff do i tell if my tires are losing pressure with this? so i opened up all the air caps and used the tool and this pressure stick stuck out when air went into the tool, and the readings were like 25, 25 25, 25. each tire seem to have the same pressure but my light was still on. so im not sure if i know exactly what im doing but can anyone give me on tips on how to fix the tire pressure signal. heres a pic of the signal

 

I run 40 psi. you may have reached the low range of the sensor. raise the PSI and retest
The TREAD Act mandates that new vehicles less than 10,000 pounds gross vehicle weight, sold in the United States, be equipped with tire pressure monitoring systems, or TPMS, beginning with the 2006 model year. TPMS systems alert drivers when the pressure in a tire falls more than 25 percent below the manufacturer’s recommended tire pressure. The TREAD Act affects passenger cars, light trucks and buses. Light-duty vehicles with dual-rear axles are excluded.

 

Recommended psi, I think, is 32psi. You need some more air in all of them.

Also, the stick tire pressure gauges aren't all too accurate. Get one of the dial ones.

 

The recommened psi is 32, 25% less is 26.25. so 25 PSI is too low.

 

i did a retest, i got 30 on the left rear tire, 25 , 25 ,25, i think cojaro is right, the stick is not accurate at all. imma go fill it up on air, i hope nothing goes wrong on my way to the gas station ><

 

Nothing will go wrong lol. Usually people who drag race on street tires will go into the high 10's low 20's for more traction.

 

will the light go away once it fills up?

 

It usually takes several miles of driving before the light goes out.

 

thanks for the help bro.

 

Wow i'm so glad i got an 07 that doesn't have this monitor. I've heard nothing but bad things about it.

 

U just need more air. But u could take it to the dealer if u are worried its covered under the warranty. Mine did that the first day i had it i took it in they took care of it

 

If this is ture than the 07 Fit should have TPMS. But they don't. Just woundering i have not heard about this yet

 

yeah thats the first thing i did but guess what.. labor day!! lol. how long did they take to fix it?

 

Man u don't want to know. It took them a day they gave me a free rent a car for the day it was there. Because it is under warranty. But they did not know if it was the psi or if it was just a faulty sensor so they told me it will take a while to find out. I think they just wanted to drive my fit around for a day

 

I'm pretty sure it's from 08 and up. Not 2006.

 

Man just add air and make sure you're above 30psi and that should go away

 

According to the service manual, 25 psi or lower will put the light on. Once you fill the tires to at least 29 psi, and drive over 28mph, the ECM will turn off the light.

 

it is suggested to be at 32 psi i have an 08 also and mine was doing the same just air it up and drive down the street it should go out

 

Gonna update for you guys on what happen. I took the fit to Honda World ,they fixed it by just pumping it up again and said they never experienced anything like this. 1st all tires were at 25psi which is rare + weird and 2nd there was no sign of leakage in any tires what so ever. They told me they are stumped and that i should watch out if the tpms signal comes on again. Lol kinda freaky how all my tires hit 25psi without any leaks, maybe the dealership sold it to me that way?

 

Yea they more than likely did and did not check it before they gave it to u. Good to hear she is back to normal for u
