Description

Unknown fault.

Effects on the driving operation

Unable to detect temperature, possible consequences:

Hard shifts with transmission oil cold.

The temperature-related deactivation of the retarder is restricted.

Possible causes

The cause might be a cable break or short-circuit to supply voltage.

If the error 'Reference voltage too high' is also present, this indicates a short-circuit to supply voltage.

If only one temperature sensor reports this error, there might be a cable break at this sensor.

Location

Engine speed sensor

(negative terminal of sensor or sensor circuit)
