MONITOR DESCRIPTION
The ECM monitors the engine oil temperature sensor and uses the sensor voltage to calculate the engine oil temperature. If the engine oil temperature sensor output voltage deviates from the normal operating range, the ECM determines that the engine oil temperature sensor circuit is malfunctioning and stores this DTC.
Example:
If the engine oil temperature sensor output voltage is higher than 4.865 V for 5 seconds or more, the ECM will store this DTC.

CAUTION / NOTICE / HINT
HINT:
Read Freeze Frame Data using the Techstream. The ECM records vehicle and driving condition information as Freeze Frame Data the moment a DTC is stored. When troubleshooting, Freeze Frame Data can help determine if the vehicle was moving or stationary, if the engine was warmed up or not, if the air fuel ratio was lean or rich, and other data from the time the malfunction occurred.
