A scan tool is needed when diagnosing an electronic throttle system. It allows the technician to access and read the system's codes and data for troubleshooting purposes. A vacuum gauge is used to diagnose problems in the engine's vacuum system, a pocket code reader is a less advanced version of a scan tool and can only read basic codes, and a spark tester is used to diagnose issues with the engine's ignition system.
