Yes, a bad Throttle Position Sensor (TPS) can show up on an OBD-II tester if it triggers a diagnostic trouble code (DTC). If the TPS is malfunctioning and affects the engine's performance or emissions, the vehicle's onboard computer will detect the issue and store a code. However, not all TPS issues will generate a DTC, so it’s possible for a faulty TPS to go undetected by an OBD-II tester in some cases. Regular diagnostic checks are recommended for comprehensive vehicle health monitoring.
