Table 3-16. Deutz Engine Fault Codes
Description
EGR actuator is mechanically blocked.
EGR actuator spring broken.
Internal electrical fault of EGR actuator.
EGR actuator can not learn stop positions.
Possibly only second failure if other EGRTV
failures occure.
EGR actuator can not learn stop positions
because procedure was interrupted.
Stop positions of EGR valve not o.k.
Internal actuator temperature above
threshold.
Injector diagnosis: Timeout of Injector
detection cylinder bank 0
Injector test: Short cut to ground on
cylinder bank 0
Injector diagnosis: Timeout of injector
detection cylinder bank 1
Injector test: Short cut to ground on
cylinder bank 1
Possible Cause
EGR actuator faulty or blocked.
mechanical damage of spring due to
overstress.
Internal damage of EGR actuator due to high
temperature or electrical wiring issue.
Error detection during the learning process.
Interruption of learning process due to
mechanical damage.
Mechanical damage of EGR actuator.
EGR valve is blocked or moving very hard.
overheating of EGR actuator

Action
Threshold for error detection is an internal ECU
threshold.
Check the EGR actuator and EGR valve to
mechanical blockage / clean.
Check for free movement of the valve. If it'S
blocked, then exchange the EGR valve.
Threshold for error detection is an internal ECU
threshold.
Exchange EGR actuator.
Threshold for error detection is an internal ECU
threshold.
Exchange EGR actuator.
Threshold for error detection is an internal ECU

Start Serdia Usecase to reset EGR actuator.
Check EGR valve and mounting situation. If
o.k. change EGR actuator.
