DTC P0105-15: Manifold Absolute Pressure / Barometric Pressure Sensor Circuit Short to Battery or Open [08/2023 - ]: Procedure

HINT: 

Make sure that the connector is properly connected. If it is not, securely connect it and check for DTCs again.

Pre-procedure1

• Disconnect the manifold absolute pressure sensor connector.
• Turn the ignition switch to ON.

• Measure the voltage according to the value(s) in the table below.

  Standard Voltage

  Tester Connection	Condition	Specified Condition	Result
  B75-3 (VC) - B75-1 (E2)	Ignition switch ON	4.75 to 5.25 V	V
  B75-2 (PIM) - B75-1 (E2)	Ignition switch ON	0.95 to 4.25 V	V

Post-procedure1

• Turn the ignition switch off and wait for at least 30 seconds.

Pre-procedure2

• None.

• Measure the resistance according to the value(s) in the table below.

  Standard Resistance

  Tester Connection	Condition	Specified Condition	Result
  B75-1 (E2) - Body ground	Ignition switch off	Below 1 Ω	Ω
  B75-3 (VC) - B75-2 (PIM)	Ignition switch off	171 to 189 kΩ	kΩ

  Result

  Proceed to
  OK
  NG

Post-procedure2

• None.

Result:
