quick question about tps

[BENZ_TO_GENZ]

installing a set of 2o" wheels on my 4.6 gen tech broke the sensor, so we ordered a new one to replace it, my question does the sensor automatically reset it self or does it need to be reprogrammed by the dealer, dealer has no clue

 

[BENZ_TO_GENZ]

any answers?

Re: tps question

Doing a search on hmaservice.com, assuming you're talking about the TPMS receiver when you say "sensor," the replacement notes (under >GENESIS(BH) > 2009 > EAS > NON-ECS > Suspension System > Tire Pressure Monitoring System > TPMS Receiver > Repair procedures > Replacement):

NOTE:
When the receiver first arrives for replacement:
1) It will be in Virgin State.
2) It will not be configured for any specific platform.
3) It will not have any sensor ID's memorized.

CAUTION
It is important to make sure that the correct receiver is used to replace the faulty part i.e. it must be High Line (95800-3M100) in order to have the correct inflation warning thresholds set.

1. Disconnect vehicle battery.
2. Remove faulty part and fit bracket assembly to new part.

(diagram)

3. Secure new part to vehicle and fit connector.
4. Re-connect battery and turn Ignition on.

This information is provide as-is with no warranty--suggest to the dealer that they should look this up or contact Hyundai.

The manual states this: (on 6-9) If there is a failed tire sensor, it is possible for TPMS to temporarily learn a replacement sensor when you drive closely to another vehicle equipped with TPMS too. In rare cases, this may temporarily delay the TPMS malfunction turning on.

So I would assume it could learn the new sensor on it's own.

will it learn it permenantly, or will the sensor go back off

i was driving around for about 15 minutes and it went off ,will it come back on

From service manual:

Wheel Location
1. Turn on condition
A. At the same time as TREAD Lamp.
B. Indicates wheel location where under inflation / leak has occurred.

2. Turn off condition
A. At the same time as TREAD Lamp.


If wheel locations change in between Ignition cycles, then the system assumes the previous Auto-Located position. Once Auto-Location completes on the current Ignition cycle, the correct lamp will be lit.

and

1. General Function
A. Auto-locate/learn takes place only once per Ignition cycle.
B. On successful completion, 4 road wheel sensor ID's, together with their respective road wheel positions are latched into memory for monitoring.
C. Until Auto-learn completes, previously learned sensors (together with their respective locations) are monitored for under inflation / leak warnings.
D. Spare tire inflation / DTC state is not displayed.

2. General Conditions to Learn New Sensors:
A. Receiver must Auto-Locate 4 road sensors.
B. Auto-location / learning only functions when speed is more than 20 kph (approx. 15 mph).
C. Receiver must determine that it is confident that sensor is not temporary:
1) Uses vehicle speed.
2) Uses confidence reduction of previously learned sensors.

D. Typical time at driving over 20 kph to learn a new sensor is up to 10 minutes.

3. General Conditions to Un-Learn a sensor that is removed:
A. It takes less than 10 minutes at 20~30kph.
B. Confidence reduction is dependant on vehicle speed and the number of sensors known to the receiver.

I think this answers your questions

All because some people are to lazy to check their tire pressures. (See end of story).

In my case, although I did not replace any sensors, I did a tire store rotate my tires for me. I was worried that something would light up, but the TPMS lamp never did come on.

Later asked my Genesis Technician "how does the car know what corner the tire is on, once the tires get rotated"? He said that each corner of the car has its own receiver to read the tire that is under it, and that is how the car knows that a sensor was moved from (example) the LR to the LF. Also learns very quickly.

Because my dealer (Orlando Hyundai) fills the tires with Nitrogen, and gives free refills if you get a flat, or have to add air between visits, and also because of the TSB that shows damage to the air valve if air pressure is checked wrong, I myself have never checked the pressure in my tires, since I purchased it. If the pressure gets 3 or 4 lbs low, the TPMS lamp will come on. I did watch the Genesis Tech check the tire pressure once, plus he checked and filled the spare tire (with 78% Nitrogen and 21% Oxygen and 1% everything else <grin>) regular air.
