Diagnostic Trouble Code (DTC) Information

Diagnostic trouble code (DTC) information ECM-200F

Condition




The diagnostic trouble code (DTC) is stored if the engine control module (ECM) registers that the engine coolant temperature (ECT), interpreted by the engine coolant temperature (ECT) sensor, does not pass -30 °C a set time after starting from cold (lower than -30 °C).
The diagnostic trouble code (DTC) is diagnosed within 5 minutes with the engine running. Decisions about a faulty sensor can only be made if the engine coolant temperature (ECT) at start up is lower than -30 °C.

Substitute value
- The engine cooling fan (FC) is activated at the predefined speed.

Possible source
- Contact resistance in the connector
- Damaged engine coolant temperature (ECT) sensor.

Fault symptom[s]
- Engine difficult to start when warm
- Engine cooling fan (FC) running continuously even when the ignition is switched off
- Malfunction indicator lamp (MIL) lit
- The engine stops, but only when it is at operating temperature
- Uneven idle.
