SFI SYSTEM(w/o Canister Pump Module), Diagnostic DTC:P16B511

DTC Code DTC Name
P16B511 Multi Flow Control Valve Sensor Circuit Short to Ground

DESCRIPTION

The ball valve position sensor is installed at the top of the water control valve shaft and detects the ball valve position.

The ball valve position sensor is a non-contact type and uses Hall elements which can yield the magnetic field strength as an electrical signal through the Hall effect, which enables output voltage corresponding to the ball valve position to be obtained linearly.

DTC No. Detection Item DTC Detection Condition Trouble Area MIL Memory Note
P16B511 Multi Flow Control Valve Sensor Circuit Short to Ground The ball valve position sensor output voltage is less than 0.55 V for 3 seconds or more (1 trip detection logic).

  • Open or short in ball valve position sensor (water control valve) circuit

  • Ball valve position sensor (water control valve)

  • ECM

 Comes on DTC stored SAE: P16B6

MONITOR DESCRIPTION

If the output voltage transmitted by the ball valve position sensor remains low, the ECM interprets this as a malfunction in the sensor circuit, illuminates the MIL and stores a DTC.

CONFIRMATION DRIVING PATTERN


  1. Connect the GTS to the DLC3.

  2. Turn the engine switch on (IG).

  3. Turn the GTS on.

  4. Clear the DTCs (even if no DTCs are stored, perform the clear DTC procedure).

  5. Turn the engine switch off and wait for at least 30 seconds.

  6. Start the engine.

  7. Idle the engine for 120 seconds or more.

  8. Turn the engine switch off and wait for at least 30 seconds.

  9. Turn the engine switch on (IG).

  10. Turn the GTS on.

  11. Enter the following menus: Powertrain / Engine / Trouble Codes.

  12. Read the pending DTCs.

    Tech Tips


    • If a pending DTC is output, the system is malfunctioning.

    • If a pending DTC is not output, perform the following procedure.

  13. Enter the following menus: Powertrain / Engine / Utility / All Readiness.

  14. Input the DTC: P16B511.

  15. Check the DTC judgment result.

    GTS Display Description
    NORMAL

    • DTC judgment completed

    • System normal
    ABNORMAL

    • DTC judgment completed

    • System abnormal
    INCOMPLETE

    • DTC judgment not completed

    • Perform driving pattern after confirming DTC enabling conditions

    Tech Tips


    • If the judgment result is NORMAL, the system is normal.

    • If the judgment result is ABNORMAL, the system is malfunctioning.

Tech Tips

Read Freeze Frame Data using the GTS. The ECM records vehicle and driving condition information as Freeze Frame Data the moment a DTC is stored. When troubleshooting, Freeze Frame Data can help determine if the vehicle was moving or stationary, if the engine was warmed up or not, if the air fuel ratio was lean or rich, and other data from the time the malfunction occurred.

PROCEDURE


  1. CHECK HARNESS AND CONNECTOR

    Tech Tips

    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
      Result
      Proceed to
      OK
      NG

  2. CHECK HARNESS AND CONNECTOR (WATER CONTROL VALVE - ECM)


    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
      D39-2 (VCFC) - D1-106 (VCWG) 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

    OK
