|Didn't want to fill anymore since I have the green caps.|
The tire pressure warning light came on about a week after the tires were rotated (and I assume filled) at the dealer.
Is it the low air indicator,,,, or the actual yellow letters "TPMS" ?
My son in law checked all 4 tires and they were above 30.
Dont mean a thing, system will also be looking for hi/low spread too,, how much above 30 ?
Didn't want to fill anymore since I have the green caps.
So,, air we breath is 78% nitrogen,, inflate the tires to 35/36 and drive, see if low air light go out after a mile or so
Light is still on.
See above,, which light is illuminated ?
Is it safe to drive on highway at 75/80 mph?
How much air is in the tires above 30 ? I prefer 36 in my own tires and drive 75 all the time on the interstate. In most respects, TPMS is of no real concern for driving, unless sensor has is actually providing valid info to module with a low pressure input below threshold value, or the module or wiring is on the fritz.. you got even air in all 4 tire above 32, low air light should go out.
IF "TPMS" is illuminated, then visit to Hyundai be in order to recover fault code and determine where the actual fault is.
HOw does this light determine low pressure.
Sensor inside each tire (mounted to wheel via stem) is sending infor to the TPMS module, consisting of module ID, temperature inside tire, pressure inside tire, and a few other tid bits of info.. the module looks at the data, and if there is excessive pressure spread between high and low, then module will turn on the low air light, which will prompt you to hopefully investigate the current situation with tire pressure gauge and find the low tire and correct the situation, be it normal air loss over time/temperature swing with marginal air to start with, or a puncture of tire needing repaired to hold air again
Why is it still on?
Which light is illumated ?
No other problem so hate to go to dealer for this but would like the light to go out.
If it the yellow "TPMS".... you going to visit dealer to find which part of overall system is at fault...
Low air indiactor,,, put 35/36 in the tires and see what happen
