Or max.) to reduce internal losses, especially since we also wanted to extend main­tenance intervals and strengthening durability. The system is designed to work in line with the Scania Driver Training program in order to maintain the skills If the fault is resolved, the fault code becomes inactive. The updated V8 range is now equipped with a new high-pressure fuel pump where the pumping elements are individually controlled via Active Inlet Metering (AIM). The engine control unit switches off the exhaust gas recirculation system. Empty the EGR cooler following the instructions given in the manual for service stations, subgroup 01-65. Rail pressure drops as the engine brakes, when the fuel metering inlet valve must be closed and the fuel is not consumed. Replace the cylinder head of the high-pressure fuel pump as described in Section H9 of Document 03: 14-01, Edition 2. CNG combustion produces fewer undesirable gases than the aforementioned fuels. Check the opening pressure of both relief valves. Both are critical when it comes to meeting the current and coming Euro 6 regulations re­garding nitrogen oxides (NOx) and particulate matter – not only when the truck is new, but also over time  as the legal demand is for at least seven years or 700,000 kilometres. The invalidation of the fault code must be executed immediately. The boost pressure is not adjusted correctly, this can lead to poor handling. The engines, which are available at 520, 580 and 650 horsepower, can reduce fuel consumption by 7 to 10 percent for customers with vehicles that have higher combined truck and trailer weights, higher average speeds, … Fuel metering inlet valve sticking or leaking. Short circuit of the charge air pressure sensor circuit.  With the extra dosing, the evaporation of the AdBlue is improved during low load cycles as the tempe­rature is higher near the outlet manifold. AdBlue capacity on each model was 75 litres. 153771739 Location Offline Senior Member Reputation: 1,054. Scania’s production units are located in Europe, South America and Asia. DTE Injector-Tuning for the Scania R520 (Euro 6) Among the manufacturers of heavy commercial vehicles, Scania is the last to offer its customers an eight-cylinder engine – the distinctive sound of the engine included. Ensure that the sensor resistance is approximately 2.5 kΩ at 20 ° C. The voltage in the electrical circuit of the air intake temperature sensor was too high. This page is having a slideshow that uses Javascript. Check the wiring to the connector and the bushing in the cylinder head. Scania R460 144G produced by Scania.

With this fault, the engine torque is reduced by 30% while the fault code is active (confirmed). Maximum speed.  I am proud to say that we have managed to reconcile these somewhat conflicting objectives”. Probably, electrical wiring or solenoid valve of cylinder 1 nozzle is faulty. There is a deterioration in the cooling efficiency provided by the charge-air cooler. Empty the EGR cooler following the instructions given in the manual for service stations, subgroup 01-65. Scania has a long and proud tradition in offering automated manual gearboxes under the Scania Opticruise name, which was first introduced in the early 1990s.  As Alexander Vlaskamp explains, this latest investment is firmly in line with Scania’s commitment to continuous improvement: “The development of a new range has been absolutely necessary,” states Vlaskamp. Engine running unevenly. This category only includes cookies that ensures basic functionalities and security features of the website. The fuel shut-off solenoid valve remains closed. Always available. An item may have several different faults. Or max.) In idle mode, the value of the charge air pressure sensor is not equal to the atmospheric pressure and / or exhaust back pressure. Cylinder 1. The EGR system turns off when the measured outside temperature is too low. Diagnose the mass flow sensor and its connectors for electrical problems. As long as this DTC is active, the engine power is limited and the EGR system is deactivated. Truck comparisons. To erase the fault code: Ensure the engine is running at moderate or heavy load. Petrol tank. Switch the ignition on and off with the key. Malfunction of the temperature sensor charge air. The fuel pressure in the fuel rail is higher than the requested. Scania R420 Service Manual Diagnosis and troubleshooting using Scania EMS Display is described in the Operator’s Manual for Scania EMS Instrumentation.
