CODE NAME
Oil temperature sensor system
CODE DESCRIPTION
If the oil temperature sensor output is 4.4 V or higher (oil temperature does not increase) even after driving for 10 minutes or more, there is an open circuit in the oil temperature sensor and diagnostic trouble code No. 15 is output.
When the oil temperature sensor output is 0.2 V or less (for 1 second or more), it is judged that there is a short-circuit in the oil temperature sensor and diagnostic trouble code No. 16 is output.
PROBABLE CAUSE
- Malfunction of the oil temperature sensor
- Malfunction of connector
- Malfunction of TCM
