Tire pressure warnings

I have a Honda fit - the warning light about tire pressure goes off every 2 weeks at least - sometimes it is off a little in one tire sometimes not. It has been suggested to put a piece of duct tape over the useless light. the owners manual says its “dangerous” levels

any one with suggestions? similar problem?


make sure your tire pressure/tire is at least what is posted on the drivers door post…many use 32 psi routinely…did you check spare? check out this web site
Honda Fit tire pressure monitoring system

Is it always the same tire? If so, you may have a leak through the valve core. You can try replacing one. You can buy the extraction tool at the same store that sells the valve cores.

I was curios what Kia considered a “significantly under inflated tire” to be.

I lowered the pressure in the left front on my 09 Rondo one pound at a time & 28 PSI is the magic number.

Reinflating & driving 10 miles turns the idiot light off.

Sounds like your Honda is more touchy then the Rondo.

On the Rondo the spare tire is not monitored

it’s been different tires - I have been taking it to the oil change place. Once they checked and there were 50 psi in the one (obviously it is not consistent)
did get a new tire gauge from Santa so will check it out with that. Just seems too frequent to be real Haven’t checked the spare though will do that

50 PSI?! I bet that is almost twice what it should be. How did you get that much pressure in one tire?

Black tape looks better than duct tape…

I think I would buy a good tire gauge and put a piece of tape over the light. I can tell in the steering of my cars if I have a low tire. My vehicles are too old to have this feature, but I made a 1200 mile rounc trip to a convention in a Ford Windstar owned by my institution that had this feature. I was driving over a section of interstate that had been milled and had only one lane in my direction. This tire warning light went on and there was no place to pull off, so I just kept going. When I finally was able to get to a rest stop, the tires seemed o.k. Fortunately, the owner’s manual was in the glove compartment and I found the switch to reset the light. It didn’t come on again, so I assume the rough pavement set the light off. A friend of mine has a 2007 Ford Escape. In cold weather, this light has come on. This is a modern feature I think I can do without.

Does this vehicle have a tire pressure reset switch ??? I have a Toyota which has a tire pressure warning light but also has a reset switch. When you inflate the tire to the proper prssure, you “reset” (the warning light).

It’s hard to figure out exactly what you’re saying. We need more concrete information. Does your system tell you exactly which tire is low? If so, what is the actual pressure in that tire when the light is on and what should the pressure be according to the placard or manual? If your system doesn’t tell you exactly which tire, then what is the actual pressure in all tires (including the spare)?

I know 50 psi - at least thats what the oil place guy told me - not sure where they get their employees and its always someone different ----so who knows. They are tiny tires on a tiny car
did get a good gauge from Santa! too cold to check it today.

I agree - seems the general consensus - it has come on almost every 2 weeks just doesn’t make any sense wanted to check with the “experts” here. the Honda site says about the same thing. Did get a good tire gauge so will check it.

Really…what Toyota is that??? My 4runner and wifes Lexus doesn’t have a switch. Just inflate tire to proper psi…and light goes off.

The Prius has a reset switch under the driver’s side dash. When the tire pressure warning light comes on, you “find” the tire(s) which are in need of air, fill it/them to the appropriate psi and then RESET this switch. I had this problem recently where filling the tire didn’t make the light go out. You have to reset the system to let the system “know” that the tire pressures set are now correct.

My wife’s 06 Sienna has a tire pressure reset switch. I’ve only had to use it after the tires were rotated as I check the pressure on a regular basis. To the OP, invest in a good quality dial gauge.

what model year? warranty? imo-either defective monitor,spare or one of them low air
i normally inflate about 2-4 psi in winters,what manual,door jam say how much air each tire(factory recommended) dont forget spare if applicable.

My Scion has a “reset” switch, the reset the light once a leak is repaired, and a “reinitialization procedure” to establish completely new references for the wheel speed sensors when the overall rolling diameter is changed from new tires. The system is so sensitive that I need to reinitialize the system every time I rotate the tires…just like it says in the owners’ manual.

Have you thoroughly read the owner’s manual?

That 50psi…was that in the compact spare? Does your vehicle use tire pressure sensors instead of wheel speed?

I would never cover a warning light with tape. The light is telling you that something is wrong and needs to be corrected. If that something is a sensor and you cover the light with tape instead of fixing the sensor, how will you know in the future when something really is wrong?

no reset switch the light does go off after air is put in - but not trusting that it’s accurate

Hi, I own 08 and 09 Honda Fit. First, there is no pressure sending unit in the Honda spare, so don’t bother looking there for the problem. There are only 4 sending units, one in each normal tire. Also, you say that the tire pressure goes off every 2 weeks. There are two tire warning lights on the Honda Fit. One is the (!) signal that says that the computer is receiving all tire sensor signals but tire pressure is low in one of them, and the other tire warning light is TPMS (Tire Pressure Monitoring System). If the computer fails to read a sensor on the Honda Fit, the TPMS light will light. This can only be corrected with fixing the sensor problem. For instance, if you take off a main tire and remove it from the vicinity of the car, your TPMS will light. When you return with the tire, the TPMS light will go out. So, if you have all main tires on, and you get the TPMS signal, one of your sensors is probably bad or you have a tire from another car with a different sensor… sensors are computer calibrated to the car at the dealers and costs $100 for the task. If all 4 of your sensors are operating properly and for the proper calibrated car, the TPMS light will stay off. The (!) light indicates a low pressure. When the tire pressure gets to about 28psi, this light will light. It will not go out until the pressure rises above approximately 28 psi. If your (!)light is on and then goes out, the pressure probably was low initially but when the tire heated up from the driving, it increased the tire pressure and turned the light out. The light does not go out instantly, however, and may take up to a half hour for the computer to reset the (!) signal. I use 35psi for all tires of both my cars, and maintain great handling and fuel economy.

My 2002 Sienna has a warning light, but my understanding is mine uses the ABS system, and warns when the tires are not rotating at pretty much the same rate. Mine also has a reset button, on the dash, left of the steering wheel. One turns the key to on without starting the motor, and holds that button down until the tire icon stops blinking.

Several years ago, we were ready to leave our house in Mexico to return to the States, and a tire was flat. We asked a cousin to take it to be repaired. When they brought it back, it had hammer marks all over it. They took it to some moron who beat it off with a hammer.

A few weeks later, I was driving across Georgia, I think it was, when the warning light came on. I pulled off at an exit and checked the tire pressures. They were all okay.

I started off, and the light came back on. At a rest stop, I pulled in and checked the tires with my hand.

That tire they had beat to crud was, ahem, other than round. My guess is it was ready to explode, but that is just my guess. I put on the spare and finished my trip. At my destination, I went to a tire shop and ordered four new ones.

One can only imagine what that warning light saved me from.

When I got back to Mexico, I told the cousin what had happened, and told him never to let anyone take a tire off with a hammer. There is a place in town which has the air driven device which simply pushes the tire off with no damage.
