Attention! The engine overload protection system is installed only on a turbocharged engine.
The engine overload protection system is used to limit engine power when the turbocharger pressure relief valve fails. A pressure sensor installed in the intake manifold measures the pressure and switches when the pressure exceeds the required value. The pressure sensor turns off the valve, which closes the vacuum in the diaphragm assembly installed on the fuel pump. In this case, the fuel pump reduces the fuel supply to the same value as in a non-turbocharged engine.
In the engine overload protection system, only the pressure sensor and the vacuum solenoid valve can be replaced.
Pressure sensor
Removal
1. The pressure sensor is located on the side of the intake manifold storage chamber next to the windshield washer reservoir.
2. Disconnect the electrical connector from the pressure sensor.
3. Unscrew the pressure sensor from the intake manifold and remove the sealing ring.
Installation
1. Installation is carried out in the reverse order of removal.
Vacuum solenoid valve
Removal
1. The vacuum solenoid valve is located at the rear of the engine compartment.
2. Disconnect the electrical connector from the vacuum solenoid valve.
3. Disconnect the vacuum hoses from the vacuum solenoid valve.
4. Unscrew the screw and remove the vacuum solenoid valve.
Installation
1. Installation is performed in the reverse order of removal. Check that the vacuum hoses are installed correctly.
