Tire Pressure Sensor

[blaze1808]

I am having an issue. I rencently plugged my tire and filled it to 32 like I had it before. The tire light is still on. I have driven it for days and turned on/off many times. Please help or any advice would be very helpful.

Are your tires really inflated properly? Don't put too much faith in your tire-pressure monitoring system (TPMS)
1. The definitive correct tire pressure is on this sticker on the door frame. This info is also in the owner's manual. Ignore what's printed on the tire sidewall. Your car manufacturer has determined what pressures will make your car handle properly. The pressure on the sidewall is the maximum pressure for any vehicle.

2. Tire pressure should be checked in the morning on cold tires, not after you've driven to Starbucks. Tire pressure changes 1 psi for every 10 degrees of outside temperature. A change from 70 F to 40 F will lower the pressure 3 psi, enough to affect wet braking and fuel economy; check your pressures monthly.

The TPMS Warning Light Remains On or Comes Back On
You have a problem. Assuming you found the low tire(s) on your vehicle and re-inflated them to the recommended pressure (using an accurate tire pressure gauge), and reset the TPMS system (unless it is supposed to reset automatically), a TPMS Warning Light that remains on means trouble.

You either have a bad pressure sensor in one of the wheels, or the TPMS system has self-diagnosed an internal fault that is prevent it from functioning normally.

TIP: The TPMS Warning Light have come back on because the tire you refilled is still leaking air. A small puncture will leak air and eventually allow the tire to get low or go flat again. Listen for any hissing sounds after re-inflating a low tire. If possible, spray some soapy water on the tire tread and look for bubbles that would indicate a leak. A tire can also leak air where the inner bead seals against the flange on the wheel rim. If the tire is leaking, it needs to be fixed.

Thank you for this but I have checked for leaks and on cooler temperatures. The only thing I have found that works is a process that involves taking apart the dash and applying a paper clip to reset the sensor.

If your tires aren't low, then you probably have a bad sensor. They are about $100 to get replaced. The light is just going to turn back on if you reset it.

I've had one before and it acted just like it said it would. It would flash for about a minute then go steady. Mine just stays on like if I had a tire with low air pressure.

I had this issue at high altitude. At 1000-6000 feet they were fine, then went up to 9000-10k feet. In the morning, cold, it lit up. Drove it back down to lower alt and it went off. Checked and filled on the first instance, but the second time I just drove it. Must be something in the device that freaks on higher elevation. Something to think about.

My tpms sensor will not go off.. since my car is a 2010, and i am going to have the rims redone, should i replace all of the tpms sensors? Tire rack has them for $42.00 each. When i replace the tpms sensors do i need to do anything else to the car or will the car find the new ones and hopefully turn the light off?

[andremike]

Can I anyone enlighten me on which TPMS sensors I should buy? The dealer wants $70.00 a sensor and $80 to reprogram the car. I see some on Rockauto that claim re-learning is not necessary.. so which is it? I also was looking on tire rack..

I still don't even know if its a bad TPMS.. but my light will not turn off.

I deal with tpms sensors at work all the time. Nissans need the tire pressure monitor IDs written to the ecu by a scan tool. Even if they use the same modules as Auto relearn Toyotas and Hondas, Nissans need the scan tool even at routine tire rotations. And all these cars need the universal replacement sensor activated by the scan tool when a sensor is replaced. Ericthecarguy has a great tpms video on YouTube. The procedure is almost the same on Nissans as Hondas.
The Schrader brand sensors on rock Auto are what came on your car. Ez sensors are almost guaranteed to work. Many tire shops have the tool and will program the sensors for only the $15 installation.

Each tire has its own battery powered sensor in its valve stem. These batteries ne d replacing periodically. Good luck

Each tire has its own battery-powered sensor in its valve stem. One or more
battery may need replacing. A good tire shop should be able to scan each tire to check its battery.
