EOT (Engine Oil Temperature)
• 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.
