Two technicians are discussing stepper motor fuel gauges. Technician A says that a defective gauge can usually be repaired individually without replacing the entire cluster of
panel gauges. Technician B says that if the power lead to the fuel tank
sending unit is disconnected from the tank unit and grounded (ignition on), the fuel gauge should go to full.
Which technician is correct?
O A. Neither Technician A nor Technician B
O B. Both Technician A and Technician B
OC. Technician A only
O D. Technician B only<\/p>\n\n\n\n
The Correct Answer and Explanation is :<\/strong><\/mark><\/p>\n\n\n\n The correct answer is D. Technician B only<\/strong>.<\/p>\n\n\n\n Technician A’s Statement:<\/strong> Technician B’s Statement:<\/strong> In summary, while Technician A\u2019s statement may hold true in certain contexts, it does not apply universally, making it less reliable. On the other hand, Technician B’s explanation is a standard troubleshooting technique and reflects a correct understanding of how fuel gauges operate in relation to the sending unit.

Technician A claims that a defective gauge can usually be repaired individually without replacing the entire cluster of panel gauges. While it is true that in some cases, individual gauges can be repaired, this statement can be misleading. The repairability of a gauge depends on the specific fault and the design of the gauge cluster. In many modern vehicles, the gauges are integrated into a single unit or circuit board, making it difficult or impractical to repair a single gauge without replacing the entire cluster. Therefore, Technician A’s assertion is not universally correct and can lead to confusion about the repairability of fuel gauges.<\/p>\n\n\n\n
Technician B states that if the power lead to the fuel tank sending unit is disconnected from the tank unit and grounded with the ignition on, the fuel gauge should go to full. This statement is accurate. When the sending unit’s power lead is grounded, it creates a condition where the gauge interprets the signal as being at its maximum level (full tank). This is a standard diagnostic test used to check the functionality of the fuel gauge and the sending unit. If the gauge moves to full when grounded, it indicates that the gauge itself is functioning properly, isolating the problem to the sending unit or its connection.<\/p>\n\n\n\n
