• Open circuit or ground short circuit of
sensor / harness.
• Battery voltage is normal
• Starter Switch signal (Engine ECU: V12
terminal) is not activated
• Sensor supply voltage is normal
• Air flow sensor voltage: 0.1 V or less
• 2.8 sec. or more
• Sensor output: 0.7 times of target value
at normal condition [default value]
• Output limitation: Approximately 75 % of
normal condition
• EGR stop
• Intake throttle 100 % open
• Refer to the sheet of "Pattern of NCD
Inducement" (Refer to page "3. ACTIVE
TEST AND UTILITY" on page 1-S17)
• Insufficient output
• Worsening exhaust gas performance
• ON (Blinking)
• Diagnostic counter = zero
–
• Engine is not stopped forcibly by engine
ECU.
However KUBOTA strongly
recommends operator to stop engine as
soon as possible.
