DTC P0365-31: Camshaft Position Sensor "B" Bank 1 No Signal; DTC P0390-31: Camshaft Position Sensor "B" Bank 2 No Signal [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 VVT sensor (for exhaust camshaft) 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
  C77-3 (VC2) - Body ground	Ignition switch ON	4.5 to 5.5 V	V
  C78-3 (VC2) - Body ground	Ignition switch ON	4.5 to 5.5 V	V
  C77-1 (EX+) - Body ground	Ignition switch ON	3.0 to 5.5 V	V
  C78-1 (EX+) - Body ground	Ignition switch ON	3.0 to 5.5 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
  C77-3 (VC2) - C77-1 (EX+)	Ignition switch off	1.425 to 1.575 kΩ	kΩ
  C78-3 (VC2) - C78-1 (EX+)	Ignition switch off	1.425 to 1.575 kΩ	kΩ
