Which category should you use for a defect in the electrical system affecting sensors and switches?

• A. Enter D for Defective under Computers, Sensors & Switches.
• B. Enter D for Defective under Other Emission Related Components.
• C. Enter F for Fault under Fuel System.
• D. Enter E for Electrical issue under Wiring.

Answer: (A)

Defects in sensors and switches are part of the electronic control system. When the problem lies in the electrical system’s sensors and the computer that reads them, the proper place is Computers, Sensors & Switches. This category specifically covers electronic components like sensors, switches, and the ECU that interpret sensor data. It’s more precise than the other paths: Other Emission Related Components covers non-electronic parts that affect emissions, the Fuel System addresses fuel-delivery issues, and Wiring is reserved for faults in the electrical wiring itself rather than the electronic control components. So a sensor/switch electrical defect belongs in the Computers, Sensors & Switches category.
