High HFM Sensor Signal
(Circuit Short)
- HFM sensing values are higher than
maximum sensing values.
- Check the resistance in HFM sensor.
- Check the ECU wiring harness
(open and poor contact).
• Check the ECU pin #82 and #84
for open circuit.
- Actual air mass flow vs. Output
voltages.

P0105
Supply Voltage Fault to
Booster Pressure Sensor
- Out of range of supply voltages about
boost pressure sensor at Ignition key-
On and Engine Stop (Higher than
specified values).

• 0.4 bar: 0.6120 V
• 1.4 bar: 2.6520 V
• 2.4 bar: 4.6920 V
- Check the sensor wiring harness
for ECU pin #100 and #108 (open,
poor contact).
- Visually check sensor and replace
if required.
- Replace the ECU if required.
- Check whether existing or not
about turbo boosting control
malfunction (P1235) simultaneously.
- If there is turbo boost control fault,
Should be checked followings also;
• Leakage before turbo system
• Vacuum pump malfunction
• Waste gate’ solenoid valve
• Turbo charger system defect or
malfunction itself
• Air inlet restriction
• Exhaust system restriction
