TPMS light stays on
We had a very cold spell a week ago today where the overnight temp got to -4 degrees. The next day I had a TPMS light on so I checked the tire pressure. 3 tires had 35 psi and the rear passenger tire had 32psi. I got my air hose out and filled to match the other 3...35psi. I've driven the car a whole week now and the light remains on. Do you think the extreme cold has done something to one of the sensors. I guess I could remove a battery cable for a few minutes to get it to go out but I think it should go out on its own as before. Last time I drove the car for just a few minutes and the light went out. Not this time.

If it is on steady then it should be a pressure issue. If the light is blinking it would indicate a problem with a sensor. Try using a different pressure gauge if the light is steady.

TPMS
Yes the light is steady after blinking a few times at start up. I'm using a digital gauge. I'll get another gauge and check it. Thanks

I get false TPMS indications from time to time. Sometimes it goes out on its own, sometimes after I add a couple of pounds to an already almost fully inflated tire. IMO, the system (at least in my '07 and '08 Nissans) is unreliable.

I have had to overinflate to about 40 psi and then deflate to normal pressure to turn off the light.

Sometimes the battery in one or more sensors get weak and they will fail during cold weather, causing a code to set and the light to stay on steady. These batteries seem to last about 6 or 7 years, so if your vehicle is a 2007 model, it sounds like a likely candidate for the problem. The batteries are not replaceable; you have to replace the entire TPMS sensor. If all of the sensors are original, you may be best off replace all four and save you some headache in the future. If one or more of the sensors are replaced, the sensor will have to be "woke up" and initialized to the TPMS control module. This would require an activation tool and a scantool, meaning you will have to take the vehicle to a dealer, tire shop or auto repair facility that has the equipment to do this. This said, you should first have the TPMS codes read to see what problem they are indicating. This would require a scantool more advanced than the code readers most auto part places use to access powertrain OBD II codes.

The rebuild on the sensors only replaces the rubber seals, so you did the right thing refusing that service if there was nothing wrong.
I replaced the sensors on my FX last year because one of them was dead. I got OEM sensors at Revolution Supply for about $25 each. They are the same sensors as OEM. Home Page It was the least expensive place I found. |

Keep us updated. I haven't had any problems with the replacements on my FX.

Sensors
Gilley I have tried to find my sensors on that home page link but from the home page when I click on the TPMS links nothing works. Its like the site is down. You can click the link but nothing happens. I was on my ipad so I went to my computer and tried it. Still didn't work. Now I'm trying it from my work computer and again it doesn't work. Wonder what's up with that?

Try this link Untitled Page. Or google revolution supply. They are in Westminster, CA.

the blinking before steady indicates a problem with a tire sensor

Keep check of your tire pressure the old fashioned way, before TPMS, and put a piece of black tape over the light and forget it. More Gov interference in our lives that cost us $$.

TPMS Fuse
Does any one of you guys know if there's a specific fuse for TPMS Light?
