Cheap OBD2 scanners are limited in which OBDII readiness systems they can check, and they cannot diagnose mechanical problems not monitored by sensors, requiring deeper diagnostic knowledge and tools.

Cheap scanners only check certain readiness systems and cannot diagnose non-sensor-monitored failures like fuel pump pressure issues, requiring manual testing and experience.
