Help
- The external power supply is faulty.
• Check the external power supply.
• Check the sensor wiring harness
(open, short, poor contact).
- Actual air mass flow vs. Output
voltages.
• -20 Kg/h: 0.47 V
• 0 Kg/h: 0.99 V
• 10 Kg/h: 1.2226 ~ 1.2398 V
• 15 Kg/h: 1.3552 ~ 1.3778 V
• 30 Kg/h: 1.6783 ~ 1.7146 V
• 60 Kg/h: 2.1619 ~ 2.2057 V
• 120 Kg/h: 2.7215 ~ 2.7762 V
• 250 Kg/h: 3.4388 ~ 3.5037 V
• 370 Kg/h: 3.8796 ~ 3.9511 V
• 480 Kg/h: 4.1945 ~ 4.2683 V
• 640 Kg/h: 4.5667 ~ 4.6469 V
- Replace the ECU if required.
- No cam recognition signal (missing
events).
- Check the source voltage of cam posi-
tion sensor (ECU pin #111) (specified
value: 4.5 ~ 12 V).
- Check the sensor wiring harness for
ECU pin #103 and #104 (open, short,
poor contact).
- Check the cam position sensor.
- Measure the air gap: 0.2 ~ 1.8 mm
- Replace the ECU if required.
- Not synchronized with Crank angle
signal.
- Check the source voltage of cam posi-
tion sensor (specified value: 4.5 ~ 12 V).
- Check the sensor wiring harness for
ECU pin #103 and #104 (open, short,
poor contact).
- Check the cam position sensor.
- Measure the air gap: 0.2 ~ 1.8 mm
- Replace the ECU if required.
- Crank angle signal faults or clearance
too close.
- Check the sensor wiring harness for
ECU pin #90 and #82 (open, short, poor
contact).
- Check the resistance of crank angle
sensor: 1090 Ω ± 15 %.
- Measure the air gap: 0.3 ~ 1.3 mm
• 1.3 mm of air gap: outputs 1.0 V at
40 rpm
• 0.3 mm of air gap: outputs 150 V at
7000 rpm
- Check the teeth condition.
• Drive plate (A/T), DMF (M/T)
- Replace the ECU if required.
