Had to replace a tpm on my 2002 Cadillac dts now that wheel shows 0lbs pressurehow do i reset it?

To reset the tire pressure monitoring system (TPMS) on your 2002 Cadillac DTS after replacing the TPM, first ensure all tires are inflated to the recommended pressure. Then, turn the ignition to the "On" position without starting the engine. Press and hold the TPMS reset button, usually located beneath the dashboard or near the steering column, until the TPMS light blinks and then turns off. Finally, drive the vehicle for a few minutes to allow the system to recalibrate.
