- P2635 – Abnormal pressure in fuel pump (history code)
- P0088 – Rail pressure abnormalities (output reduction)
3. Fuel Injection System Fault Codes
These codes indicate issues with the injector solenoids and fuel injection system, which may cause engine misfires, loss of power, or improper fuel delivery.
- P1211 – Injector rail A solenoid valve drive system fault (GND short circuit) – affects cylinders 1 & 4
- P1214 – Injector solenoid valve drive system common rail 2 fault (GND short circuit) – affects cylinders 2 & 3
- P1212 – Injector rail A solenoid valve drive system failure (+B short-circuit/open circuit) – affects cylinders 1 & 4
- P1215 – Injector solenoid valve drive system common rail 2 failure (+B short-circuit/open circuit) – affects cylinders 2 & 3
- P1601 – Multi-point fuel injector correction exception (output reduction)
- P0201-P0204 – Solenoid injector circuit breakers for cylinders 1 to 4
- P0263-P0272 – Cylinder correction faults for cylinders 1 to 4
4. EGR System Fault Codes
Errors in the EGR (Exhaust Gas Recirculation) system can lead to emissions problems and engine performance loss.
- P0489 – EGR valve solenoid malfunction (open circuit/GND short circuit)
- P0490 – EGR valve solenoid malfunction (VB short circuit)
- P0404 – EGR valve stuck (output reduction)
- P0405 – EGR valve safety sensor fault (LO)
- P0406 – EGR valve safety sensor fault (HI)
- P0234 – Turbo boost too high (output reduction)
- P0217 – Overheating detected (output reduction)
- P0219 – Engine coaster issue
- U1001 – CAN communication interruption (vehicle communication failure)
5. ECU System Fault Codes
These codes relate to electronic control unit (ECU) issues, affecting the overall performance of the excavator.
- P0611 – ECU poor charging circuit (LO) (output reduction)
- P0200 – ECU poor charging circuit (HI)
- P0605 – ROM exception
- P0606 – CPU failure (engine will not start)
- P0607 – CPU monitoring IC exception (output reduction)
