1. When the actual engine speed does not match the target idling speed, this corrects the injection volume.
   If this item displays 10 mm³/st or more or -10 mm³/st or less even with the engine completely warmed up and the air conditioning and other electrical loads off, the internal parts of the engine may be damaged, or the fuel injection system or other auxiliary components may be malfunctioning.

2. Injector deterioration
   
3. Decrease in cylinder compression
   
4. Injector compensation code is incorrectly set (forgot to input code after replacement or made mistake during setting of code after replacing ECM with one from another vehicle)
   

1. When idling after warmup, the injection amount for each cylinder is corrected to optimize the difference between the engine speed of each cylinder.
   Example: For cylinders that are slowing the engine speed compared to other cylinders, the injection volume is increased.
   
2. "Injection Feedback Val" more than 3.0 mm³/st: Injector breakdown is causing injection volume deviation, or insufficient compression is causing poor combustion.

2. This indicator can be used for diagnosing supply pump related malfunctions.
   
3. When this value (absolute value) is large, it indicates that the difference between the actual and target fuel pressure is also large.
   A positive value indicates that the pressure feed is being increased due to insufficient pressure. A negative value indicates that pressure is being reduced due to excessive rail pressure.
   When the suction control valve does not close properly, it causes rail overpressure, and this value and the "Pump SCV Learning Value" slip to the negative volume side.

   The injection amount is determined based on the injection timing and fuel pressure.
   Also, the spray pattern is selected based on the fuel pressure.
   
5. For startup, at least 25000 kPa of fuel pressure is needed (take care as there is a response lag when the pressure rises).
   
6. When the fuel pressure is below 25000 kPa, it may cause rough idling.
   
7. When the fuel pressure has decreased by 20000 kPa from the target fuel pressure, there may be a lack of power.
   
8. If actual fuel pressure is 5000 kPa higher than the target fuel pressure, P1229 will be stored. When the actual fuel pressure is lower than the target fuel pressure, "P1608 Lack of Power" may be detected depending on the degree of deviation from the target pressure.
   
9. When the fuel pressure is higher than 250000 kPa, DTC P0088 will be stored.

3. Normally, the value is between 800 and 2500 mA.
   
4. If the value is stuck at 3000 mA or higher, it indicates that the operation is poor (poor movement due to deposits, etc.).
