If the purge valve tested O.L from a terminal to the body of the terminal, what would that indicate?

When the purge valve tested open loop (O.L) from a terminal to the body of the terminal, it indicates that there is a break in continuity or an open circuit. This means that the purge valve itself is not completing the electrical circuit necessary for operation. Therefore, the correct interpretation is related to the functionality of the component being tested.

In this case, testing O.L signifies that the purge valve is not functioning as intended, which conflicts with the suggestion that it represents a "good component." A component that tests O.L in this context typically points to a fault such as being open (an interruption in the circuit), which is why this conclusion is valid.

For clarity, an open test result indicates that the part isn't operational due to a lack of continuity, whereas a functional component would register some form of resistance or continuity when tested. Thus, it reinforces that the proper understanding of O.L is essential in diagnosing electrical components effectively within engine performance diagnostics.
