I don't know where the sensor is but you may want to check your fuses.

You lost the programming. Here are the instructions to re-program.

1. Locate the Data Link Port. It is located under dash drivers side. Be sure you know which pins are 8 and 4. (Notice port is wider on top row) 2. Make sure there are metal contact pins in terminals 8 and 4. Connect 8 to 4 with a suitable jumper wire (leave the jumper wire connected throughout the programming procedure). Make sure you know which terminals are 8 and 4. The vehicle will respond by locking and unlocking the doors to signify entering of programming mode. 3. Press and hold both the LOCK and UNLOCK buttons together on the first transmitter to be programmed. After about 15 seconds, the vehicle will respond by locking and unlocking the doors. Release the buttons on the transmitter. 4. Within one minute, repeat the previous step on the remaining transmitters to be programmed. 5. Remove jumper wire applied to the OBDII Port. Disclaimer

Release the buttons on the transmitter.

huh, my 99 Tahoe owners manual only mentions step three, nothing about any of the rest.
Anyways, mine stopped working too.
I replaced battery.
Still no workie.
Used key for months until I got around to it.
Decided maybe new battery was not really a new battery.
Opened transmitter and decided maybe the battery was in upside down.
That was the problem.
