What provides an oil temperature reading on the Vehicle Engine Monitoring Display (VEMD)?

• A. Oil pressure gauge
• B. The probe
• C. Temperature sensor
• D. Cooling system indicator

Answer: (B)

The probe plays a critical role in providing an oil temperature reading on the Vehicle Engine Monitoring Display (VEMD). It is designed to directly measure the temperature of the engine oil by making contact with the oil or being immersed in it. This allows it to accurately gauge the oil's thermal state, which is crucial for monitoring engine performance and ensuring proper lubrication.

The information obtained by the probe is then relayed to the VEMD, where it is displayed for the operator. This highlights the importance of the probe in the overall engine monitoring system, as it ensures that the operator has real-time data on oil temperature, which can be vital for making informed decisions regarding engine management and maintenance.

While other options may relate to engine monitoring, they do not directly provide the oil temperature reading in the same manner as the probe. The oil pressure gauge indicates pressure levels rather than temperature, the temperature sensor typically refers to a more general device that could have various applications, and the cooling system indicator focuses on the temperature of the coolant rather than the oil specifically. Thus, the probe is essential for delivering the specific oil temperature data that is displayed on the VEMD.
