Diagnostic Trouble Code (DTC) Information

Diagnostic trouble code (DTC) information ECM-6220

Condition




The engine control module (ECM) monitors the engine temperature under different running conditions. If the signal from the engine temperature sensor corresponds to a temperature that is higher than a specific limit value despite a low engine load and speed, the control module interprets this as a fault and the diagnostic trouble code is stored.
The diagnostic trouble code (DTC) can be diagnosed when the engine is running.

Possible source
- Insufficient coolant in cooling system.

- Damaged engine cooling fan (FC) control module.
- Contact resistance or oxidation in the connectors.
