CHECKING THE FUEL PRESSURE SENSOR

Note. If diagnostic trouble codes (DTC) for the fuel pressure sensor or atmospheric pressure sensor are stored, these diagnostic trouble codes (DTC) must be fault-traced and remedied first.

HINT: The method below is used to check whether the diagnostic trouble code (DTC) was caused by a faulty fuel pressure sensor. This can be done by comparing the fuel pressure sensor signal (displayed in VIDA or appropriate scan tool) with the actual fuel pressure (displayed on a manometer connected to the wiring for the fuel injection system). This method assumes that the manometer for measuring fuel pressure is correctly calibrated.

Scheme 85

Scheme 86

1. Connect the manometer. See: «FUEL PRESSURE GAUGE»(ref-479171-S17915099052012061200000) CAUTION: The pressure in the fuel injection system can reach approximately 650 kPa when this diagnostic trouble code (DTC) is stored. Use an adapted manometer.
2. Run the engine to operating temperature. Allow the engine to idle.
3. Air conditioning (A/C) off. Read off the relative fuel pressure. The relative fuel pressure is calculated from the fuel pressure sensor and the atmospheric pressure sensor signal (= absolute pressure minus atmospheric pressure). Check that the value on the manometer and the value displayed in VIDA (or appropriate scan tool) are the same. If the values are different, the circuit for the fuel pressure sensor is defective.

Is the fuel pressure sensor correct?

1. YES Refer to «CHECKING COMPONENTS»(ref-466656-S12507353182012042500000)
2. NO Refer to «CHECKING THE COMPONENT AND WIRING»(ref-466656-S23632317162012042500000)

CHECKING COMPONENTS

Check that the fuel level in the tank is not too low (almost no fuel).

Check the connectors between the fuel pump (FP) control module and the fuel pump (FP). Check for contact resistance. Check for oxidation.

Check the fuel lines and fuel filter for blockage and leaks.

Remedy as necessary.

Try a new fuel pump (FP) if no fault is found during the above fault-tracing.

HINT: The diagnostic trouble code (DTC) can also be caused by a defective fuel pump (FP) control module.

FAULT-TRACING INFORMATION

The fault should have been detected and remedied. As this is not the case fault-tracing has failed.

Exit fault-tracing for this diagnostic trouble code (DTC) or make another attempt.

FAULTY SIGNAL

See FAULTY SIGNAL

Note. If diagnostic trouble codes (DTC) for the fuel pressure sensor or atmospheric pressure sensor are stored, these diagnostic trouble codes (DTC) must be fault-traced and remedied first.

HINT: The method below is used to check whether the diagnostic trouble code (DTC) was caused by a faulty fuel pressure sensor. This can be done by checking whether the fuel pressure sensor signal (displayed in VIDA or appropriate scan tool) is unstable, while the actual fuel pressure (displayed on a manometer connected to the wiring for the fuel injection system) is stable.

1. Connect the manometer. See: «FUEL PRESSURE GAUGE»(ref-479171-S17915099052012061200000) CAUTION: The pressure in the fuel injection system can reach approximately 650 kPa when this diagnostic trouble code (DTC) is stored. Use an adapted manometer.
2. Run the engine to operating temperature. Allow the engine to idle.
3. Air conditioning (A/C) off. Read off the relative fuel pressure. The relative fuel pressure is calculated using the signals from the fuel pressure sensor and the atmospheric pressure sensor (= absolute pressure minus atmospheric pressure). Check the value on the manometer and the value displayed in VIDA (or appropriate scan tool). If the fuel pressure sensor signal (displayed in VIDA or appropriate scan tool) is unstable while the actual fuel pressure (displayed on the manometer connected to the wiring for the fuel injection system) is stable, this indicates that the circuit for the fuel pressure sensor is defective.

Is the fuel pressure sensor correct?

Scheme 88

1. Run the engine to operating temperature. Allow the engine to idle.
2. air conditioning (A/C) off
3. Read off the fuel pressure and the fuel pressure desired value.
4. Start the quick test when the engine is running at idling. During the course of the quick test, the control module will steer the pressure to different target values in different stages (400, 500, 600 and finally 700 kPa), after which the pressure will be decreased in stages to the same pressure. Each stage lasts for approximately 5 seconds. NOTE: Because the by-pass valve in the fuel pump (FP) will be open at approximately 650 kPa, the pressure will not go higher than this. HINT: An example of normal regulation is (Scheme 88) The upper digital display and the graphic display (red font color) indicate the absolute fuel pressure, calculated from the fuel pressure sensor The central digital display and the graphic display (blue font color) indicate the control module target value for the absolute fuel pressure The lower digital display indicates the relative fuel pressure (white font color), calculated from the fuel pressure sensor and the atmospheric pressure sensor (= absolute pressure minus atmospheric pressure). If a manometer is connected during the test, it must indicate this pressure. Check that the value for absolute fuel pressure is the same as the target value for absolute fuel pressure. If the values are not the same, this indicates a fault in the pressure regulation. The values may differ during the quick test when the target value is changed. This is due to sluggishness in the fuel regulation and is normal. In some cases, it can take up to 5 seconds before the fuel pressure reaches the target value for the fuel pressure.

CHECKING REGULATION OF THE FUEL PRESSURE

HINT: The method described below is used to check the control of the pressure in the fuel injection system by activating the quick test for the fuel pump (FP). If the pressure gauge for pressures up to 650 kPa is connected, the fuel pressure sensor can also be checked during this test.

Note. In this test, the complete flow capacity of the system is not tested.

Scheme 89

1. Disconnect the manometer unless it is adapted for pressures higher than 650 kPa
2. Run the engine to operating temperature. Allow the engine to idle.
3. air conditioning (A/C) off
4. Read off the fuel pressure and the fuel pressure desired value.
5. Start the quick test when the engine is running at idling. During the course of the quick test, the control module regulates the pressure for different target values in different steps (530, 490, 450, 410, 440, 490, 530 kPa). The test usually starts with the pressure momentarily going up to 650 kPa. NOTE: Because the by-pass valve in the fuel pump (FP) will be open at approximately 650 kPa, the pressure will not go higher than this. HINT: An example of normal regulation is (Scheme 89) The upper digital display and the graphic display (red font color) indicate the absolute fuel pressure, calculated from the fuel pressure sensor The central digital display and the graphic display (blue font color) indicate the control module target value for the absolute fuel pressure The lower digital display indicates the relative fuel pressure (white font color), calculated from the fuel pressure sensor and the atmospheric pressure sensor (= absolute pressure minus atmospheric pressure). If a manometer is connected during the test, it must indicate this pressure. Check that the value for absolute fuel pressure is the same as the target value for absolute fuel pressure. If the values are not the same, this indicates a fault in the pressure regulation. The values may differ during the quick test when the target value is changed. This is due to sluggishness in the fuel regulation and is normal. In some cases, it can take up to 5 seconds before the fuel pressure reaches the target value for the fuel pressure.

2. NO Refer to «CHECKING COMPONENTS»(ref-466656-S20413578032012042500000)

HINT: The fault may be intermittent or be due to the flow capacity in the system being too low.

Check that the fuel level in the tank is not too low (almost no fuel).

Check the fuel lines between the fuel pump (FP) and the fuel rail for the injectors for leakage.

Check the fuel pressure sensor connectors. Check for contact resistance and oxidation.

Check the connector for the fuel pump (FP) control module. Check for contact resistance. Check for oxidation.

Check the fuel lines and fuel filter for blockage.

Remedy as necessary.

Try a new fuel pump (FP) if no fault is found during the above fault-tracing.

If the fault is intermittent, do not verify fault-tracing if the fault does not recur.

It is possible to view the information again, or leave fault-tracing for this diagnostic trouble code (DTC).

HINT: After carrying out the repair, check that the fault has been remedied.

1. Connect the manometer. See: «FUEL PRESSURE GAUGE»(ref-479171-S17915099052012061200000)
2. Run the engine to operating temperature. Allow the engine to idle.
3. Air conditioning (A/C) off. Read off the relative fuel pressure. The relative fuel pressure is calculated from the fuel pressure sensor and the atmospheric pressure sensor signal (= absolute pressure minus atmospheric pressure). Check that the value on the manometer and the value displayed in VIDA (or appropriate scan tool) are the same. If the values are different, this indicates incorrect function.

Is the function OK?

1. YES VERIFIED: Troubleshooting has been completed.
2. NO Refer to «INFORMATION»(ref-466656-S13277647232012042500000)

HINT: After carrying out the repair, check that the fault has been remedied.

1. Run the engine to operating temperature. Allow the engine to idle.
2. air conditioning (A/C) off
3. Read off the fuel pressure and the fuel pressure desired value.
4. Start the quick test when the engine is running at idling. During the course of the quick test, the control module will steer the pressure to different target values in different stages (400, 500, 600 and finally 700 kPa), after which the pressure will be decreased in stages to the same pressure. Each stage lasts for approximately 5 seconds. NOTE: Because the by-pass valve in the fuel pump (FP) will be open at approximately 650 kPa, the pressure will not go higher than this. HINT: An example of normal regulation is see scheme 51 The upper digital display and the graphic display (red font color) indicate the absolute fuel pressure, calculated from the fuel pressure sensor The central digital display and the graphic display (blue font color) indicate the control module target value for the absolute fuel pressure The lower digital display indicates the relative fuel pressure (white font color), calculated from the fuel pressure sensor and the atmospheric pressure sensor (= absolute pressure minus atmospheric pressure). If a manometer is connected during the test, it must indicate this pressure. Check that the value for absolute fuel pressure is the same as the target value for absolute fuel pressure. If the values are not the same, this indicates a fault in the pressure regulation. The values may differ during the quick test when the target value is changed. This is due to sluggishness in the fuel regulation and is normal. In some cases, it can take up to 5 seconds before the fuel pressure reaches the target value for the fuel pressure.

CHECKING FUSES

All heated oxygen sensors are supplied with voltage with the same lead. If the lead is damaged, e. g., fuse on the lead, then diagnostic code for heating for all heated oxygen sensors will be stored.

Therefore, check first if diagnostic trouble codes for heating are also stored for other heated oxygen sensors.

HINT: Brake vacuum pump is supplied with voltage via the same lead as the heated oxygen sensors. A damaged brake vacuum contact can lead to the pump running continuously and in the long-term be overheated and damaged. In turn, this leads to damaged fuse.

HINT: Therefore, check the brake vacuum switch and pump before any continued troubleshooting is done on the heated oxygen sensors.

REPLACING THE THERMOSTAT

Note. This diagnostic trouble code (DTC) is stored if the engine coolant temperature (ECT) sensor freezes. This may happen if the coolant level is low or there is too little glycol in the coolant. Check the engine coolant level and its freezing point. Remedy as necessary.

The engine control module (ECM) has registered that the actual temperature increase has deviated from the calculated temperature increase. This deviation is due to a damaged thermostat.
