SFI SYSTEM(w/o Canister Pump Module), Diagnostic DTC:P019011

DTC Code DTC Name
P019011 Fuel Rail Pressure Sensor "A" Circuit Short to Ground

DESCRIPTION

B006YB4E47

The fuel pressure sensor (for high pressure side) is installed on the fuel delivery pipe (for high pressure side). The fuel pressure sensor (for high pressure side) changes the fuel pressure for high pressure side into an electrical signal and sends the signal to the ECM. Then the ECM controls the pump discharge using this feedback to maintain the fuel's target pressure between 2.4 and 20 MPa (25 and 204 kgf/cm2, 348 and 2900 psi).

DTC No. Detection Item DTC Detection Condition Trouble Area MIL Memory Note
P019011 Fuel Rail Pressure Sensor "A" Circuit Short to Ground The fuel pressure sensor (for high pressure side) output voltage is less than 0.293 V for 3 seconds or more (1 trip detection logic).

  • Open or short in fuel pressure sensor (for high pressure side) circuit

  • Fuel pressure sensor (for high pressure side)

  • ECM

 Comes on DTC stored SAE Code: P0192

Tech Tips

When this DTC is output, check the fuel pressure (for high pressure side) in the Data List. Enter the following menus: Powertrain / Engine / Data List / Fuel Pressure (High).

DTC No. Fuel Pressure (High) Malfunction
P019011 Approximately 0 kPag

  • Short to ground in PR circuit

  • Short in PR to EPR circuit

  • Open in VCPR circuit

If the Data List values is normal it may be due to a temporary recovery from the malfunction condition. Check for intermittent problems.

MONITOR DESCRIPTION

This DTC is stored if the fuel pressure sensor (for high pressure side) output voltage is out of the standard range due to an open or short in the sensor circuit.

Example:

If the fuel pressure sensor (for high pressure side) output voltage is less than 0.293 V for 3 seconds or more, the ECM will illuminate the MIL and store this DTC.

Frequency of Operation Continuous

CONFIRMATION DRIVING PATTERN


  1. Connect the GTS to the DLC3.

  2. Turn the ignition switch to ON.

  3. Turn the GTS on.

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

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

  6. Start the engine [A].

  7. Idle the engine for 10 seconds [B].

  8. Turn the GTS on.

  9. Enter the following menus: Powertrain / Engine / Trouble Codes [C].

  10. 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.

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

  12. Input the DTC: P019011.

  13. 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 has a malfunction.

    • If the judgment result is INCOMPLETE, perform steps [B] through [C] again.

CAUTION / NOTICE / HINT

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

    Front view of wire harness connector

    (to Fuel Pressure Sensor (for High Pressure Side))

    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 fuel pressure sensor (for high pressure side) connector.

    2. Turn the ignition switch to ON.

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

      Standard Voltage
      Tester Connection Condition Specified Condition
      d3-1 (VC) - d3-2 (E2) Ignition switch ON 4.75 to 5.25 V
      d3-3 (PR) - d3-2 (E2) Ignition switch ON 3.0 to 5.25 V

    4. Turn the ignition 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
      d3-1 (VC) - d3-3 (PR) Ignition switch off 171 to 189 kΩ

      Tech Tips

      Perform "Inspection After Repair" after replacing the fuel pressure sensor (for high pressure side).

  2. CHECK HARNESS AND CONNECTOR (FUEL PRESSURE SENSOR (FOR HIGH PRESSURE SIDE) - ECM)


    1. Disconnect the fuel pressure sensor (for high pressure side) 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
      d3-1 (VC) - C57-98 (VCPR) Always Below 1 Ω
