• Abnormality Judgment 

  Judge NG when the continuous time of completing all the malfunction criteria of Low side or High side below becomes more than the time (3 seconds) needed for diagnosis.

• Judgment Value 
  JUDGMENT VALUE (ABNORMALITY JUDGMENT)
  
  

  Malfunction Criteria	Threshold Value
  (Low side)

  Throttle position	> 15°
  Output voltage	≤ 0.985 V
  (High side)
  Engine speed	600 ← → 900 rpm
  Throttle position	≤ 2°
  Output voltage	> 2.81 V

Time Needed for Diagnosis  : 3 seconds

Malfunction Indicator Light Illumination  : Illuminates when malfunction occurs in 2 continuous driving cycles.
