Multiple Choice

Which issue may cause the engine to start in any gear on an auto-shift transmission vehicle?

Explanation:
The issue that can cause the engine to start in any gear on an auto-shift transmission vehicle relates to the start enable relay. In vehicles equipped with an auto-shift transmission, the start enable relay is a safety feature designed to prevent the engine from starting unless the transmission is in a specific gear, usually neutral or park. If this relay is defective, it may fail to correctly detect the transmission's gear status. As a result, the system may not restrict the engine from starting while the vehicle is in gear, posing a significant safety risk. In contrast, the brake light switch primarily monitors the status of the brake lights and doesn't directly influence the vehicle's ability to start in gear. Low engine oil pressure is more related to engine lubrication issues than to transmission functions, and worn fuel injectors affect engine performance but not starting behavior with respect to transmission gear. Thus, the defective start enable relay is the issue that directly connects to the problem of engine starting in any gear.

    Interesting resource, but some sections feel light on detail and I still need a different source for heavy hydraulic configurations. The randomization is nice and flash cards help, but it isn’t enough on its own. It's decent as a supplementary tool.

    After finally taking the real exam, I felt a lot more confident thanks to this set. The explanations are clear, the multiple-choice questions cover typical truck and transport scenarios, and the flash cards helped lock in key terms. The randomized order kept me sharp. Examzify works great on mobile.

    Excellent for confidence growth. The mix of questions, crisp explanations, and the ability to review wrong answers quickly helped me target weak areas. Examzify on my phone makes late-night study painless. I felt prepared after finishing a full set before the test.
