DTC P16B5-15: Multi Flow Control Valve Sensor Circuit Short to Battery or Open [12/2017 - ]: Procedure

HINT: 

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

1. Disconnect the water control valve connector.
2. Turn the engine switch on (IG).
3. Measure the voltage according to the value(s) in the table below.

   Standard Voltage

   Tester Connection	Condition	Specified Condition
   D39-2 (VCFC) - D39-3 (EFCV)	Engine switch on (IG)	4.5 to 5.5 V
   D39-1 (FCV) - D39-3 (EFCV)	Engine switch on (IG)	3.0 to 5.0 V

4. Turn the engine switch off and wait for at least 30 seconds.
5. Measure the resistance according to the value(s) in the table below.

   Standard Resistance

   Tester Connection	Condition	Specified Condition
   D39-2 (VCFC) - D39-1 (FCV)	Engine switch off	190 to 210 kΩ
   D39-3 (EFCV) - Body ground	Always	Below 1 Ω

   Result

   Proceed to
   OK
   NG

Result: 

OK

See step  2

1. Disconnect the water control valve connector.
2. Disconnect the ECM connector.
3. Measure the resistance according to the value(s) in the table below.

   Standard Resistance

   Tester Connection	Condition	Specified Condition
   D39-1 (FCV) - D1-74 (FCA)	Always	Below 1 Ω
   D39-3 (EFCV) - D1-83 (EWGA)	Always	Below 1 Ω
   D39-1 (FCV) or D1-74 (FCA) - Body ground and other terminals	Always	10 kΩ or higher

   Result

   Proceed to
   OK
   NG

Result: 

OK
