Which of the following is not considered a good troubleshooting method in pneumatic systems?

• A. Systematic testing
• B. Isolating sections
• C. Replacing parts randomly
• D. Shotgun technique part replacement

Answer: (D)

Effective pneumatic troubleshooting relies on a systematic, step-by-step diagnostic approach. By testing components and signals in a controlled way and isolating sections of the system, you can pinpoint where the fault lies without guessing. Replacing parts randomly ignores measurements and observations, wastes time and money, and can introduce new issues. A shotgun approach—replacing multiple parts without a logical rationale—has the same drawback. So, random part replacement is not considered a good troubleshooting method.
