Engine Temperature - Signal Implausible
Diagnosis conditions
- A temperature model is formed. If the measured temperature deviates too much from the calculated temperature, a fault is detected.
NOTE:
- A thermostat which is constantly open can cause the fault P0115.
Possible fault cause
- Thermostat (permanently open)
- Open coolant shutoff valve (only Tiptronic vehicles)
- Wiring
- Temperature sensor faulty
- DME control module faulty
