• The EOT sensor is a two (2) wire thermistor type sensor.
• The EOT sensor’s internal thermistor forms a voltage divider with a pullup resistor inside the ECM.
• The ECM monitors engine oil temperature via the EOT sensor signal to aid in controlling fuel rail pressure (FRP) and fan control.
• The EOT signal allows the ECM to compensate for oil viscosity variations due to temperature changes in the operating environment, ensuring adequate power and torque are available for all operating conditions.
