Diagnostic Trouble Code (DTC) Information

Diagnostic trouble code (DTC) information ECM-P011600

Condition




The engine control module (ECM) monitors the engine temperature using a sensor.
The diagnostic trouble code (DTC) is stored if the control module detects that the value from the engine coolant temperature (ECT) sensor deviates too much from the value for intake temperature after the engine has been switched off for an extended period.
The diagnostic trouble code is diagnosed at ignition on once per driving cycle, but only when the fuel temperature has dropped by at least 20 °C and has ended up near the outdoor temperature from the previous driving cycle.

Hint: The diagnostic trouble code may be set incorrectly if, for example, a retrofitted engine heated is used.

Substitute value
- During start-up: The intake air temperature (IAT) is used if no fault has been detected on the intake temperature sensor
- After start-up: The engine coolant temperature (ECT) is calculated based on a model.
- Engine cooling fan (FC) is activated at the predefined speed.

Possible source
- Contact resistance in connector.
- Damaged engine coolant temperature sensor.

Fault symptom[s]
- Malfunction indicator lamp (MIL) lit.
- Engine reluctant to start.
- Uneven idle.
- Engine stops.
- The engine cooling fan (FC) runs continuously even when the ignition is switched off.
