How do you reset a 97 Nissan tps sensor?

To reset the throttle position sensor (TPS) on a 1997 Nissan, start by disconnecting the battery for about 15 minutes to clear the ECU's memory. After reconnecting the battery, turn the ignition to the "ON" position without starting the engine, and then fully open and close the throttle several times to allow the ECU to recalibrate the TPS. Finally, start the engine and let it idle for a few minutes to ensure the system adjusts properly. If the issue persists, consider checking the TPS for proper voltage and functionality.
