Installation Guide
Model Matching
Confirm that the oil pump model is consistent with the vehicle engine specifications to avoid abnormal fuel supply due to mismatch.
01
Seal Inspection
Check the integrity of the seal ring before installation to ensure that it is not aged or damaged to prevent fuel leakage.
02
Fuel System Cleaning
Use a 10μm filter to filter the fuel. It needs to settle for 48 hours before installation to prevent impurities from clogging the spray hole.
03
Connection and Fixing
- Use anti-vibration tools to fix the oil pump to ensure that it is aligned with the drive shaft;
- Firmly connect the oil pipe and the circuit to avoid looseness and interruption of fuel supply.
04
Pressure Test
After installation and before starting, use the injector tester to detect the oil pressure (standard pressure range: 19600-22540 kPa) to ensure no leakage.
05
Testing and fault diagnosis for high-pressure fuel pumps
Visual inspection
Before control unit diagnostics are undertaken, it is first advisable to carry out a visual inspection of the individual system components as part of initial troubleshooting activities. In this way, leaks in the fuel lines or defective plug connections on the sensors can be localised and eliminated in advance.
Reading the error memory
In this function the error codes stored in the error memory can be read out and deleted. In addition, information on the error code can be called up.
In our case study, the electrical plug connection on the fuel pressure control valve was disconnected and consequently the error code P2294 was stored in the error memory.
Error code P2294 - fuel pressure regulator / solenoid valve
Break in the circuit
Signal missing / no communication
Error permanent
Reading off parameters
In order to check and assess the system pressures, the parameters of the high and low-pressure sensors from the control unit should be looked at first.
And in order to narrow down possible causes of errors, the displayed actual values can be compared with the target values set by the vehicle manufacturer.
The high-pressure circuit is always tested after the low-pressure circuit has been tested and no errors detected.
Checking fuel low pressure
The fuel pressure sensor for low pressure is installed in the feed line to the high pressure pump and sends its signal to the engine control unit.
As a result of such information, the engine control unit can calculate the required low pressure accordingly and forward the signal to the fuel pump control unit for demand-based activation of the pump.
Pre-supply pressure in normal operation approx. 4.0 bar
Pre-supply pressure for cold or hot start approx. 7.0 bar
In the case of a defective sensor, the pre-supply pump is controlled with a fixed value by the engine control unit and the pressure is raised accordingly. If the fuel pump control unit is defective, the pre-supply pump will not be activated.
Checking fuel high pressure
The fuel pressure sensor for high pressure is screwed into the distributor pipe (rail) and sends its signal to the engine control unit. The data is evaluated in the engine control unit and the high pressure is adjusted accordingly via the high pressure control valve. In the event of a defective sensor, the control valve is activated by the control unit with a fixed substitute value.
