DTC P0105-11: Manifold Absolute Pressure / Barometric Pressure Sensor Circuit Short to Ground [12/2023 - ]: 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 ON.

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

  Standard Voltage

  Tester Connection	Condition	Specified Condition	Result
  C74-3 (VC) - C74-2 (E2)	Ignition switch ON	4.75 to 5.25 V	V
  C74-1 (PIM) - C74-2 (E2)	Ignition switch ON	3.0 to 5.0 V	V

Pre-procedure2

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

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

  Standard Resistance

  Tester Connection	Condition	Specified Condition	Result
  C74-3 (VC) - C74-1 (PIM)	Ignition switch off	171 to 189 kΩ	kΩ

  Result

  Proceed to
  OK
  NG

Post-procedure1

• None.
