Regardless of whether or not an auxiliary device like the A/C or heater is active, if the alternator duty is always at the maximum value, there is an electrical system abnormality, like battery deterioration.

1. When the (actual) fuel pressure is equal to the target fuel pressure, this value becomes 0.
   
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.
   

1. Injector clogging
   
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.
   
3. Even if "Injection Feedback Val" for a cylinder is less than -3.0 mm³/st, the cylinder with this value does not necessarily have a problem.
   

   HINT:

   1. The ECM adjusts each cylinder so that the average "Injection Feedback Val" of the 4 cylinders is approximately 0 mm³/st.

1. Diagnosis is possible when the MAF reading is between 30 and 140 gm/s.
   
2. When the air intake volume is very low, such as when idling, due to excessive pressure fluctuation the correct values will not be displayed.

1. This number indicates the correction value (0 point calibration) for compensation of variance in the differential pressure sensor.
   
2. If the value of DPF Differential Pressure does not approach 0 kPa when the ignition switch is ON (engine is stopped) and the Diff. Press. Sensor Corr. displays less than -1.5 kPa or more than 1.5 kPa, there may be a malfunction in the differential pressure sensor.
   
3. Note that the output of the differential pressure sensor fluctuates depending on the temperature.
   

1. Exhaust fuel addition injector clogged
   
2. DPF catalyst deteriorated
   

1. Usually Exhaust Fuel Addition FB is between 0.86 and 1.41.
   
2. Exhaust Fuel Addition FB is a correction value to increase the fuel volume injected from the exhaust fuel addition injector when the catalyst temperature does not rise to the target range during PM forced regeneration.
   
3. If the correction value is more than 1.45, a clog in the exhaust fuel addition injector assembly or fuel filter may be causing a reduction in injection volume or a problem with the engine (injectors, EGR, etc.) where the exhaust gas temperature decreases may be present. As a result, the catalyst temperature does not rise properly causing the catalyst to deteriorate.

1. If PM (Particulate Matter) builds up in the DPF catalyst, the pressure differential from front to rear of the DPF catalyst gradually increases.
   
2. For example, at 3000 rpm (no load), if Catalyst Differential Press is 0.45 or more, "Blocked" appears on the intelligent tester display. In this case, clogging of the DPF catalyst, an injector system malfunction, differential pressure sensor system malfunction, exhaust leaks and a MAF meter malfunction are possible causes of the malfunction.
   
3. Clogging of the DPF catalyst may be caused by the use of an oil that does not meet the specifications, such as using an engine oil that is not low-ash.
   
4. Clogging of the DPF catalyst may also be caused by a high rate of engine oil consumption.
