0x01F0E5, Coolant Temperature Sensor Open Load
- check coolant temperature sensor - replace coolant temperature sensor - check wiring harness - for further information see workshop manual - clear error memory
What you'll see
No driver-visible symptom recorded.
System reaction
- this DTC is stored in the error memory - heating operation is disabled Heater Actions: * This DTC is an error * Temporary Interlock is activated * counter "SZ / general error counter" is incremented
Diagnostic depth
Enable Condition: This error is monitored while heater is active. (LS.Internal.HeaterStateSimplified = HeaterBurnerStarting or LS.Internal.HeaterStateSimplified = HeaterBurnerActive or LS.Internal.HeaterStateSimplified = HeaterBurnerStopping or LS.Internal.HeaterStateSimplified = HeaterBurnerNotActive) Mature Threshold: Open load in coolant temperature sensor circuit detected. This DTC is reported by the heater core software. De-mature Criteria: Stable combustion reached after restart of heater: Heating request is switched off (HeaterModeRequest = DeactivateHeater) and on (HeaterModeRequest = NormalMode) and state HEATER RUNNING is reached
- defect coolant temperature sensor - coolant temperature sensor not connected to ECU - defect in wiring harness - ECU hardware failure
