Diagnostic Method
WARNING: This page is about a different variant/trim than selected.
- Abnormality Judgment
Judge NG when the continuous time of completing the malfunction criteria of Low side or High side below becomes more than time needed for diagnosis.
- Judgment Value JUDGMENT VALUE (ABNORMALITY JUDGMENT)
Malfunction Criteria Threshold Value (Low side) Output voltage ≤ 0.75 V Engine speed ≥ 1000 rpm Amount of intake air ≥ 90 kg (198 lb)/h Intake manifold pressure ≥ 80 kPa (600 mmHg, 24 inHg) (High side) Output voltage ≥ 1.6 V Engine speed 600 - 1500 rpm Amount of intake air ≤ 25 kg (55 lb)/h Intake manifold pressure >≤ 47 kPa (352 mmHg, 14 inHg) - Time Needed for Diagnosis:
Low side 3 seconds
High side 10 seconds
Malfunction Indicator Light Illumination : Illuminates when malfunction occurs in 2 continuous driving cycles.
- Normality Judgment
Judge OK and clear the NG when the malfunction criteria below are completed.
- Judgment Value JUDGMENT VALUE (NORMALITY JUDGMENT)
Malfunction Criteria Threshold Value (Low side) Output voltage > 0.75 V Engine speed ≥ 1000 rpm Amount of intake air ≥ 90 kg (198 lb)/h Intake manifold pressure ≥ 80 kPa (600 mmHg, 24 inHg) (High side) Output voltage ≤ 1.6 V Engine speed 600 - 1500 rpm Amount of intake air ≤ 25 kg (55 lb)/h Intake manifold pressure ≤ 47 kPa (352 mmHg, 14 inHg)
