Volvo All Engines (2017 Emissions) Fault Code: P066611 PID: EMS Control Module Internal Temperature Sensor “A”
Volvo All Engines (2017 Emissions) Fault Code: P066611 PID: EMS Control Module Internal Temperature Sensor “A”
Circuit description
This diagnostic trouble code (DTC) is used to indicate temperatures at the engine control module (ECM). The DTC will be set if the ECM temperature is too high. A faulty ECM temperature can lead to power loss.
Conditions for diagnostic trouble code (DTC)
Internal fault in electronic control unit (ECU)
Probable cause
1) ECM – Engine Control Module
