MIL on and one or more of the following DTCs are stored in the ECM data memory:

  • P310B  (low-pressure fuel system regulation, fuel pressure outside tolerance).
  • P129F  or P008B  (low-pressure fuel system, pressure too high).
  • P129E  or P008A  (low pressure fuel system, pressure too low).
  • P2540  (low-pressure fuel system, pressure out of range).
  • P0087  (rail fuel pressure system, pressure too low).

Technical Background

Due to fuel intrusion into the low-pressure system fuel pressure sensor (G410), a false signal may be sent to the controller, resulting in a reading that is out of tolerance.

Comparing Measure Value Block 103 with 106 is not an accurate method to diagnose low-side fuel pressure sensor G410.

In order to diagnose G410 accurately, use a mechanical gauge and compare results with the low-side fuel pressure Actual Value in Measured Value Block 103.

Production Solution

Improvements to G410 fuel pressure sensor.

Service

  1. Verify that 24T4 UPDATE - Fuel Pressure Sender (Warr_Ext)  was performed (if applicable).
  2. Verify the customer did not run out of fuel at the time the DTCs were stored.
  3. Follow indication of GFF for applicable DTCs.
  4. To check the low-side fuel pressure sensor G410, measure the fuel pressure with a mechanical gauge using the following method:
    1. Start engine and allow to idle for at least one minute.
    2. Stop the engine.
    3. Keep the ignition on.
    4. Measure actual low-side fuel pressure via mechanical gauge (VAG 1318) on the low pressure supply line in the engine compartment (Figure 1).
      G07982396
  5. Add 1 bar to the value obtained from the mechanical gauge to calculate the adjusted gauge measurement value.
  6. Compare the adjusted gauge measurement value to the Actual Value stored in MVB 103 field 1.
  7. If the MVB 103 field 1 value deviates more than ±1.0 bar from the adjusted gauge measurement value, then the DTC was likely triggered by a faulty G410 low-side fuel pressure sensor. In this case, document the adjusted gauge measurement value and MVB value on the Repair Order and perform the Sensor replacement procedure below.

Sensor replacement procedure

  1. Replace the G410 low-side fuel pressure sensor.
    G07982397
  2. Clear DTCs and verify that the problem was eliminated.
  3. Run Basic Settings 103 to adapt system.
  4. Do not replace the high pressure fuel pump, electrical fuel pump, fuel pump control module, or fuel filter unless problem persists and further diagnosis indicates a malfunction of any of these components.
