DTC 3E3-02-Fuel injection correction has exceeded a minimum limit
Control Module : ECU
Context:
The Engine Control Unit (ECU) A-9000 checks the plausibility of the Zero Fuel Quantity Calibration (ZFC) energizing
time. The ZFC is used to correct pilot injection quantity. If the ECU A-9000 determines the energizing time of the ZFC
is implausible, this fault will occur.
Cause:
The ZFC is used to compensate for aging injectors. If the compensation limit is exceeded, this fault will occur.
Possible failure modes:
1. Faulty fuel injectors, worn.
2. Faulty ECU A-9000, software.
Solution:
1. Use the appropriate service manual to perform a leakage test in the high pressure fuel system. Also, test the fuel
injectors for internal and external leakage.
A. If any faults are found, repair as necessary.
B. If no faults are found, check the ECU A-9000 for the appropriate software and re-flash, if necessary.
