Hi,

How many sensors were replaced? Does the spare tire have a sensor on it as well? If so, is the tire pressure low on the spare?

Next, when the sensors are installed, the transmitter ID needs to be registered with the TPMS module. Was that done? How were the new sensors programmed?

Let me know.

Four tires were programmed.
The extra tire didn't have TPMS sensor.
The sensors were programmed with scanner where the Sensor I D were registered on the module.

Have you tried resetting the light? There is a reset button above the DLC. See pic below.

Let me know. If there are no codes, the light won't go off, the tire pressure is where it should be, and the reset doesn't fix the issue, recheck to see if there is a signal from each wheel. One of the sensors may not be working or when programming the new sensors, it may not have worked.

Let me know.

The tire pressure light is off now, and the tire pressure was low. The tire pressure on the scanner was different from the real pressure on the gauge. that was the problem.
