2. If the value is -40°C (-40°F) or 140°C (284°F), the sensor circuit is open or shorted.
   

1. This is the intake air temperature at the intake manifold (after the intercooler).
   
2. During fail-safe operation, the value is set to 165°C (329°F). As the value is set to a high temperature, the turbo pressure may be suppressed and there may be a lack of power.

3. Can be used for judging whether or not a malfunctioning component in the electrical system is generating continual generation requests (e.g., battery deterioration is causing an unending full recharge request, etc.). 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.

2. Indicates the average engine speed of all cylinders during cranking.
   

1. MT: Manual transmission
   
2. ECT 6th: Automatic transmission
   

1. Injection amount for each combustion.
   
2. If injector assemblies are clogged, fuel quality is poor, the fuel filter element sub-assembly is clogged, or engine friction increases, "Injection Volume" will increase.
   
3. If there is a malfunction due to low turbocharger pressure or a low intake air volume, the injection volume is limited and there is a lack of power.
   

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. Only calculated and reflected at idle.
   

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 8 cylinders is approximately 0 mm³/st.
      
   2. If more than one cylinder has a positive correction value, a normal cylinder may have a value less than -3.0 mm³/st.
      

1. When the fuel pressure becomes 15000 kPa or less, "Main Injection Period" is set to 0.
   
2. When the engine will not start, confirm that injection is performed.
   
3. When P0093, P0627, P062D or P062E is stored, there is an engine stall request. At that time, "Main Injection Period" equals 0.

1. Suction control valve malfunction
   
2. Clogged fuel filter element sub-assembly
   

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. Inspect the (actual) fuel pressure, comparing it with the common rail target value.
   
2. Considered normal when the actual fuel pressure is within +/-5000 kPa of the target fuel pressure under stable conditions when idling after warming up the engine.

2. Inspect by comparing the fuel pressure with the target fuel pressure.
   
3. When in a stable condition such as when idling after warming up the engine, the fuel pressure is within +/-5000 kPa of the target fuel pressure.
   
4. The ECM uses fuel pressure for feedback control of the target fuel pressure via the fuel supply pump assembly.
   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 230000 kPa, DTC P0088 will be stored.
   

1. ON: Intank fuel pump is operating.
   
2. Only for vehicles equipped with a double tank.

2. Clogged fuel filter element sub-assembly

2. Value is large when a high fuel pressure is desired.
   
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.).
   
5. When this deviates from the standard value, it indicates that for some reason, even though the pump is running hard, the actual fuel pressure is inconsistent with the target fuel pressure.

1. This is the output voltage of the EGR valve position sensor.
   

1. This EGR Motor Duty #1 is calculated based on Target EGR Valve Pos. to actuate the No. 1 EGR valve assembly.
   
2. This EGR Motor Duty #2 is calculated based on Target EGR Valve Pos #2 to actuate the No. 2 EGR valve assembly.
   
3. To 0%: Close side EGR valve actuation.
   
4. To 100%: Open side EGR valve actuation.
   
5. When this value is large but the actual valve position does not reach the target valve position, there is an unable to open malfunction.
   

1. This value is the EGR position sensor output voltage.
   
2. When the value is at the upper or lower limit of the normal range, it is possible that a foreign object is lodged in the EGR valve seat area.
   
3. As the lower and upper limits are 3.5 V and 4.5 V respectively, if the value becomes stuck at either of these values, there is a malfunction in the lift sensor or the valve position may be misaligned (foreign matter is present, etc.).
   

1. Ignition switch to ON: 60 to 80%
   
2. Warmed-up and idling: 10 to 80%

2. Fully open: 100%.
   

There is no connection with the accelerator. However, under full load, the throttle is usually fully open (100%).

1. When the ignition switch is turned from ON to off and 5 seconds elapse, learning of "Throttle Close Learning Val." and "Throttle Close Learning Val #2" will be complete.
   
2. When "Throttle Close Learning Val." is outside of the normal range, a foreign object may be lodged in the throttle valve (for bank 1).
   
3. When "Throttle Close Learning Val #2" is outside of the normal range, a foreign object may be lodged in the throttle valve (for bank 2).
   
4. If the value is stuck at the upper limit of 21.25 deg, there is a chance that a malfunction is present.
   However, as the initial value for the learned value is 21.25 deg, it is necessary to check the value after learning is completed.
   

1. Inspect while comparing with "MAP".
   
2. With the accelerator fully open, if the actual manifold absolute pressure (MAP) is low compared to the target booster pressure by at least 20 kPa for 5 sec. or more, a feeling of a lack of power will occur.
