Tpms light on, dic indicated low tp fr, inflated to proper pressure,tpms stays on, dic wont update


TPMS - TIRE PRESSURE MONITOR WARNING LIGHT
NOTE: Tire pressure rises and falls depending on heat caused by vehicle's operation and the outside temperature. If outside temperature is low, the air inside the tire may cool, causing a lower tire inflation pressure. This may cause the low tire pressure warning light to illuminate.

When the tire pressure warning light comes on, immediately check the air pressure of all tires and adjust to the specified pressure. Make sure the warning light goes off. If the warning light stays on or flashes, there is a malfunction in the TPM system. See appropriate manufacturer service information.

Hope this helps; also keep in mind that your feedback is important and I`ll appreciate your time and consideration if you leave some testimonial comment about this answer.

Thank you for using FixYa, have a nice day.

Tire pressure warning light stays after I have checked the pressure in all tires and they are within specs. The manual tells me to push the reset button to turn it off. Where is the reset button locate...


I had the same issue. The spare tire also has a sensor, so make sure you check the tire pressure of that tire as well.
The reset button is below the traction in line with your right knee. I used my cellphone camera and and that is how i found it.

The words tire reset keep on popping up on my dashboard. What does that mean, and how do I get rid of it? 2004 Ford Freestar.


With and without "Mesage Center" respectively (pretty sure)

With the engine on...

Push "Setup" button, until your driver display says something like "Press Reset for system check".

Then push Reset. The system check will start, rotating through a series of checks.

About the fifth or sixth check will be the tire pressure. The system will sound the tone (same one that starts w/the light) and It'll say something like "Check Tires Pressure" on that moment press and hold for 3 or 4 seconds Reset. When you release the Reset button It'll show "Hold Reset if tires are OK". While that's up, hold the Reset button. After 3 or 4 seconds, the tire warning light will blink 2 or 3 times and then will stop .You need to be ready for it, because you don't get very long to release.

How to reset the low tire pressure warning if the vehicle does not have the "Message Center"

Turn the ignition to the ON position,
depress and Trip/odometer button (located in the instrument cluster) until "TIRE RESET" or "CHECK TIRE AND RESET" is displayed in the odometer display window.
Once "TIRE RESET" or "CHECK TIRE AND RESET" is displayed, press and hold the button for three seconds.
The low tire warning indicator light will flash three times as the low tire warning system begins to initialize.

This information is in the Owners Manual

Hope it helps

Upside horse shoe with exclamation point shows on dash


That would be your TPMS (Tire Pressure Monitoring System) light. If you set your tire pressures to the tire pressure listed on the sticker on the drivers door you should be ok. Note, you will have to drive the car more than 20mph for at least 15 seconds for the light to go out.

If the light stays on, and you just had tire(s) repaired or replaced you should return to the place that installed them and have them diagnose and repair the problem.

If you switched the rims (because you have a separate set of snow tires mounted on rims already, or have aftermarket rims now) then you might not have sensors in those rims and may have to deal with the light. The place that changed them should have told you this though.

If none of the above applies, and you put air in your tires and it didn't help, then you should turn to your local Hyundai dealer for a diagnosis. They have a special scan tool specific to Hyundai for reading that control module, it's codes, and it's live data from the tire pressure sensors. They should be able to make a fast diagnosis and get you on your way.

Good luck!

The check tire pressure light and ABS auto traction sensor light keep coming on. Tire pressure is good


The tire pressure monitor detects any changes in the tire inflation pressure. Therefore, it must initialize and store it in its memory if the tires or wheels have been replaced, re-inflated or the tires have been rotated. You should be able to re-initialize the system by following these steps:

1. check and make sure that your tires are inflated to the correct pressure

2. turn the ignition switch to the ON position. If the low tire pressure warning light comes on, push and hold the tire pressure warning reset switch (think the switch is in the glovebox, but not sure) until the warning light turns off and then release the switch.

3. now press and hold the tire pressure warning reset switch until the low tire pressure warning light blinks three times.

4. initialization is *not* completed until driving at the vehicle speed of 19 mph or over for more than one hour. the tire pressure monitoring starts when initialization is completed.

Tire pressure light is on


You cannot reset them,Make sure that you check the pressures in the tires. The Infiniti Tire Pressure Monitoring System is designed to trip the warning light anytime the pressure in any of the tires drops below 29 psi. At 29 psi it really won't look like the tires are low. You could have one tire at 29 or 28 causing the light to stay on all the time. Check your pressures, set at 34 or 35 to be safe, or whatever pressure the tire is recommended to be. Not all infiniti vehicles with TPMS have the display that shows the pressure in each tire. If the pressures are above 29 psi, Then there could be an issue with one or more of the sensors. If you have the tires replaced you will have to have the sensors relearned at the dealer. Tire rotations do not require the same.

I have a panel indicater light on


That horseshoe-looking warning icon on your instrument panel is a cross-section of a tire. It indicates that tire pressure is low in one or more wheels. It may also inndicate that one or more tire-pressure sensors in the wheels is faulty (small battery is worn out). The air valves on yoiur rims are equipped with pressure sensors, mounted on the inside of the rim. These sensors send a wireless signal to an on-board sensor that reports low tire pressure or faulty sensor. So, check your tire pressure. It may take a few days for that icon on the dash to extinguish.

Tire pressure warning light stays on all the time for no reason


The tire pressure monitor must be re-calibrated, this is a dealer only repair, no one else will touch it, these systems are very trouble prone.
