Description
The measured boost pressure rises above the warning limit during operation.
Failure Mode Indicator
FMI 16 – Above normal operating range – moderately severe.
Failure Mode
Fault code is stored and warning lamp is activated. Engine speed is limited to 1500 rpm (SL2) and engine power will be reduced (FL1). CAN message indicates active fault. No recovery before system reset.
Possible Cause
- Too high fuel injection quantity (mg/str) for the engine type (tuning chip)
- Incorrect nozzles for the engine type
- Incorrect turbo charger for the engine type
- Boost pressure wiring is defective
- Boost pressure sensor is defective
- Control unit is defective
Diagnosis and Solution
Find cause for the high boost pressure indication:
- Check, that the control system is configured according to the original specification and no additional devices have been attached.
- Check that the nozzles and the turbocharger meet the original specifications.
- Check the boost pressure sensor wiring, connectors and contact surfaces of the connector pins (possible oxidation).
Boost Pressure Intake Manifold Temperature Sensor
- Check the boost pressure sensor operation.
Boost Pressure Intake Manifold Temperature Sensor
- Check the ECU operation with another EEM3 controller. If the system is functional and the fault is not active with the replacement ECU, then the original ECU is defective.
