受影响的车辆

条件

MIL在和一个或多个下列故障码存储在ECM数据存储器：

^P310B(低压燃料系统的管制，燃料的压力以外的容忍)

^P129F或P008B(低压燃料系统，压力太高)

^P129E或P008A(低压燃料系统，压力太低)

^P2540(低压燃料系统中，压力超出范围)

^P0087(轨道燃料系统的压力，压力太低)技术背景

比较测量值的框103 106不是一个准确的方法来诊断的低端电压力传感器G410的。

为了诊断G410准确地使用机械的衡量和比较的结果与低端电压力的实际价值的适用

测量值块(由不同的引擎)。

生产方案

不适用的。

服务

1. 验证客户没有运行的燃料时，Dtc被存储。

提示：

P310B和/或P129E/P008A可能伴随P1250的。 如果是这样，这是有可能的故障的发生是由于低燃料的水平并不是一个故障该G410压力传感器。

2. 按照指示GFF适用Dtc的。

3. 检查的低端电压力传感器G410，衡量燃料的压力与机械的衡量使用如下方法：

a. 启动发动机，并允许闲置了至少一分钟。

b. 停止引擎。

c. 保持点火。

464

d。 衡量实际的低端电压力通过机械的衡量(VAG1318)在低压电源线发动机室(图1)。

4. 添加1条得到的数值从机械计算调整后的测量值。5. 比较调整后的测量值的实际值储存在适用于低压台的。

提示：

在某些情况下，台的实际价值是显示在hPa而不是酒吧。 为便于比较，1bar=1000hPa;(5000hPa=5条)。

6. 如果台值偏离多吗？.0条所调整的测量值，然后DTC是有可能触发一个错误的G410

低端电压力传感器。 在这种情况下，文件调整后的测量值和台的价值在修订和执行

传感器的置换过程如下。

传感器的置换过程1. 替代G410低端电压力传感器。

2. 明确Dtc和验证问题是消除。

3. 如果适用的话，运行基础设置适应低压系统。

465

4. 不替换高压燃料泵、电燃料泵、燃料泵控制模块或燃料过滤器，除非问题仍然存在，并进一步

诊断表明故障的任何这些部件。

Affected Vehicles
Condition
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
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 the applicable
Measured Value Block (varies by engine).
Production Solution
Not applicable.
Service
1. Verify the customer did not run out of fuel at the time the DTCs were stored.
Tip:
P310B and/or P129E / P008A may be accompanied by P1250. If so, it is likely the faults occurred due to a low fuel level and not a malfunction of
the G410 Pressure Sensor.
2. Follow indication of GFF for applicable DTCs.
3. To check the low-side fuel pressure sensor G410, measure the fuel pressure with a mechanical gauge using the following method:
a. Start engine and allow to idle for at least one minute.
b. Stop the engine.
c. Keep the ignition on.
  499
d. Measure actual low-side fuel pressure via mechanical gauge (VAG 1318) on the low pressure supply line in the engine compartment (Figure 1).
4. Add 1 bar to the value obtained from the mechanical gauge to calculate the adjusted gauge measurement value.
5. Compare the adjusted gauge measurement value to the Actual Value stored in the applicable low pressure MVB.
Tip:
In some cases, the MVB actual value is shown in hPa instead of bar. For comparison, 1 bar = 1000 hPa; (5000 hPa = 5 bar).
6. If the MVB value deviates more than ?.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.
2. Clear DTCs and verify that the problem was eliminated.
3. If applicable, run Basic Settings to adapt low-side pressure 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.
