Max.: 10000 rpm

Min.: 0 rpm,

Max.: 6000 rpm

• 50 to 400 rpm: Cranking

• 700 to 800 rpm: Idling with warm engine

When the crankshaft position sensor is malfunctioning, "Engine Speed" is approximately 0 or varies greatly from the actual engine speed.

Cause of Out of Range:

• Crankshaft position sensor

• Crankshaft position sensor circuit

Min.: 0%,

Max.: 100%

• Idling: 11.4 to 16.4%

Cause of Out of Range:

Malfunction in which turbo pressure or Mass Air Flow decreases.

Min.: 0 kPa,

Max.: 255 kPa

• With the ignition switch to ON, when the difference between the atmospheric pressure sensor and intake manifold absolute pressure is 10 kPa or more, there is a malfunction in one of the sensors.

• With the ignition switch to ON, when the atmospheric pressure is 0 kPa or 140 kPa, there is a malfunction in the sensor circuit.

• Standard atmospheric pressure: 101 kPa.

• For every 100 m increase in elevation, pressure drops by 1 kPa.

  This varies by weather (high atmospheric pressure, low atmospheric pressure).

Cause of Out of Range:

Atmospheric pressure sensor itself has failed (atmospheric pressure sensor is inside the ECM).

Min.: 0 kPa,

Max.: 255 kPa

• 85 to 100 kPa: Idling

• 110 to 135 kPa: Engine running at 3000 rpm

• When the ignition switch is on or the vehicle is idling, the intake manifold absolute pressure and atmospheric pressure are approximately the same (standard atmospheric pressure = 101 kPa).

  Above approximately 1500 rpm, the turbo becomes effective and the pressure becomes higher than atmospheric pressure.

• Inspect while comparing with "Target Booster Pressure".

• 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 seconds or more, a feeling of insufficient power will occur.

• No electrical load at idling: 20 to 60%

• High electrical load at idling: 100%

• This is outputs the alternator generation duty and is used to determine the electrical load.

• Can be used to determine whether a higher-than-normal injection volume at idle, etc. is due to electrical loading or from some other source.

  For example, when the duty is not high but the idling injection volume is high, there is injector volume degradation or high engine friction.

• 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.

• When "Throttle Close Learning Val." is outside of the normal range, a foreign object may lodged in the throttle valve.

• 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.

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

• 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 slip to the negative volume side.
