New Throttle Body, New Module, Same Problem...Now What?

A truck came in with a “lost communication with throttle actuator” code and a long list of replaced parts—but the problem was never the parts. This video shows why communication codes get misdiagnosed and how the parts cannon took over. Using scope data and simple logic, the real cause is uncovered: an intermittent bad ground that only failed under load. A quick, practical reminder of why verifying powers and grounds matters before replacing anything. 📘 Want to Learn More About Diagnostics?
