I just had new tires put on by NTB and one of the TPMS sensors have a bad valve so they ended up replacing it. Now my TPMS light is on and they can't reprogram the sensor into my obd, where can I take it to to get reprogram aside from the dealership?

Tire Discounters has a tool that can "sniff" the sensors after they have been installed and dump the new info via the OBDII port.

I hope it can read the codes. Our reader cant read codes from the aftermarket sensors. Im hoping they wrote the codes down for you prior to installing the new one.

They were able to read the code with a Tech400 scanner and was able to load it to the obd2 port, the scanner indicated that the transfer was successful but the light is still on, this time it's blinking for about 2 minutes than it just stays on. The guy wrote all the codes down for me but the spare didn't indicate a code, it just read oem part #. The air pressure on the spare is good and before I changed tires I never had an issue.

I have an appointment with the stealership on Wednesday, hopefully I can solve this issue before then so I don't end up spending $125.

If there is an issue with one of the sensors on the tires that got replaced, go back to the place that did the tires and ask for them to refund you. Quite a few people have to do that at my dealer when a tire shop brakes a sensor.

I went back to the place and talked to the manager, he said that when I am done with Toyota bring the invoice to him and he will file a claim to reimburse me (NTB will reimburse me for paying Toyota to service me sensor).

The manager also recommend that they order a sensor from Toyota and put it on then they'll program it and see if it work. I'm currently having them swap out the universal sensor with a oem sensor, will update in about.

Okay so they put in the new oem sensor in and rescan, load up the codes and the TPMS light is off. Damn universal sensor! The megahertz on the universal sensor wasn't the same as the other OEM sensor so even when the codes are loaded onto the OBD2, it was still indicating that the universal sensor was bad.

I've seen a procedure that they use for new RAV4s to initialize all the sensors. They inflate all of the tires to 44psi. Then, you go around to each tire and within 30 seconds (per tire), you remove at least 6psi. This activates the sensor.

 

[dj06482]

Here goes (from AllData):

1. Turn the ignition switch to the "ON" position and check that the Low Tire Pressure Warning Light blinks.

2. Press the valve core to reduce the tire inflation pressure rapidly by 6 psi (0.4 kgf/sq.cm 40 kPa) or more within 30 seconds. If the tire inflation pressure is NOT reduced by 6 psi (0.4 kgf/sq.cm, 40 kPa) or more within 30 seconds, the tire pressure sensing transmitters will NOT be activated.

This operation is required for the system to be activated and must be performed for each tire (including the spare tire), one at a time.

Check that the Low Tire Pressure Warning Light goes OFF after all the tire pressure sensing transmitters are activated.

NOTE : After all tire pressure sensing transmitters are activated, the Low Tire Pressure Warning Light will come ON whenever the tire pressure in any of the tires falls below 24 - 27 psi (1.65- 1.9 kgm/sq.cm, 165 - 185 kPa).

3. Check that the sleep mode Diagnostic Trouble Codes are NOT stored in the system. If the sleep mode Diagnostic Trouble Codes are stored, increase the tire inflation pressure of all 5 tires to 44 psi (3.0 kgm/sq.cm, 300 kpa) and repeat steps 1 - 3.

4. If the Low Tire Pressure Warning Light comes ON, increase the tire inflation pressure to 32 psi (2.2 kgm/sq.cm, 220 kpa) and check that the warning light goes OFF.

5. Adjust the tire pressure to the specified level as indicated on the tire and loading information label on the vehicle. Check that the Low Tire Pressure Warning Light is OFF.

HINT:
^ If there is a great difference between the current temperature of the tire and wheel (for example: shop temperature) and expected temperature (outdoor temperature), this needs to be considered when adjusting the tire pressure.
^ Adjust the tire pressure when the tires are cold.
