Fuel Rail Pressure Sensor Inspection

NOTE:  Since there is no direct method to test the component itself, troubleshooting is performed on the related components.

Test Procedure 

Unit output voltage inspection

• Preparation
• • -

    Fuel rail pressure sensor connector (3P) : disconnected

• Procedure
• • Jump the fuel rail pressure sensor connector (3P) terminals No. 1 and No. 2 with a jumper wire.
  • Turn the vehicle to the ON mode.
  • Confirm the HDS [Fuel Pressure Converted From PF Sensor Voltage].

• Normal Conditions
• • -

    HDS [Fuel Pressure Converted From PF Sensor Voltage] value is less than 4.89 V  .

Results 

• If it is normal, there is a problem with the fuel rail pressure sensor.
• If it is abnormal, there is a problem with other related components.
