Volvo All Engines (2017 Emissions) Fault Code: P260300 PID: EMS Coolant Pump “A” Control Circuit High
Volvo All Engines (2017 Emissions) Fault Code: P260300 PID: EMS Coolant Pump “A” Control Circuit High
The engine control module (ECM) will set a diagnostic trouble code (DTC) if the sensor signal is not within predetermined limits, or the signal is not rational.
Conditions for diagnostic trouble code (DTC):
1) Short circuit to battery voltage on A14.EA:4
Diagnostic operating conditions
1) Ignition key in ON position
Observable symptoms
1) High fuel consumption
2) Engine fan constantly engaged
Probable cause
1) Connector
2) Wiring harness
3) Engine Control Module (ECM)
