What is the time duration before the OIL PX (red) light activates while at idle if the pressure readout is between 15-40 psi?

When the pressure readout is between 15-40 psi while the system is idling, the OIL PX (red) light is designed to activate after a specified interval to allow for brief fluctuations in oil pressure that can occur naturally due to system dynamics. The correct duration for the OIL PX light to activate is 5 seconds. This delay helps to prevent unnecessary warnings due to transient conditions that may be temporary and not indicative of a genuine problem. This mechanism is important for ensuring that operators do not react hastily to momentary drops in oil pressure, which could lead to confusion or unnecessary maintenance actions.

A shorter duration, like immediate activation or just a few seconds, might lead to false alarms, while a longer duration could delay necessary responses in the event of an actual oil pressure failure. Thus, a 5-second delay strikes a balance between sensitivity and reliability, ensuring that the warning system functions effectively under varying conditions.
