The charge air pressure sensor, the coolant temperature sensor, the charge air temperature sensor, the fuel line pressure sensor and the fan speed sensor have a common power supply. MID144 Volvo VECU Control Unit Fault Codes, International Trucks Service Repair Manuals PDF. Re: Scania R450 fuel economy by Driver Pete » Mon Jan 07, 2019 11:10 am V8Lenny wrote: My R450 6x2 has not been as economical as Scania claims … All sensors must give the same readings. Switch off the ignition. The engine stops or goes into emergency mode. If the fault is resolved, the fault code becomes inactive and can be erased. The charge pressure is not adjusted correctly, danger of overload. Elimination: The DTC clears within 30 seconds. The T&D Awards winners are included, along with a 12 page supplement on the IVECO S-WAY. The coolant temperature has not changed, although the engine has a large load. The value of the coolant temperature does not change even though the engine is working with a high load. If the supply pressure deviation over a certain time interval is 1.0 bar or more, the fuel filter may be clogged. Troubleshoot by comparing the charge-air temperature sensor with the atmospheric pressure sensor and the backpressure sensor in the exhaust system. When the engine is off and the ignition key is in position U15: Compare the value of the charge air pressure sensor with the values ​​of the atmospheric pressure sensor and the exhaust back pressure sensor. Connect the wires to the engine control unit. Also make sure that the connecting pipes are intact and not compressed. Zużycie paliwa ciągnika siodłowego Scania R420 Topline z 2004 roku, ... Fuel consumption of the 2004 Scania R420 Topline with loaded semitrailer. An active DTC cannot be deleted from the control unit. There is a fault in the sensor or its wiring / connectors. The massive Truck & Driver Christmas issue is on sale now. Malfunction affects vehicle emissions of nitrogen oxides (NOx); on the instrument cluster a warning lamp lights up, warning of a high level of pollutants. On engines equipped with an EGR system, the engine control unit will turn off the system.

Make sure that the radiator is not clogged with dirt and sludge. If this DTC is re-generated, follow these steps: Ensure the sensor is at the correct distance from the camshaft gear. There is a risk of misfire. Cylinder 5, Cylinder balance (min.  With the extra dosing, the evaporation of the AdBlue is improved during low load cycles as the tempe­rature is higher near the outlet manifold. The minor difference in fuel consumption between the two will pale into insignificance when something goes wrong with either. engine oil consumption, and the compression ratio and maximum cylinder pressure have been raised to further improve combustion and fuel efficiency. Check the opening pressure of both relief valves. Check the integrity of the safety valve as described in Section H3 of Document 03: 14-01, Edition 2. Replace the turbine bypass solenoid valve. Small leakage in the high pressure section of the fuel system. The signal from the coolant temperature sensor does not change. Or max.) The voltage in the electrical circuit was above normal. The voltage in the electrical circuit was above normal. Resistance must be infinite. Malfunction of the temperature sensor air intake T126. With the sensor disconnected, the voltage should be approximately 5 V. Check the air intake temperature sensor T126 and its connectors and wiring. Restoration of the fuel supply occurs after the engine speed becomes less than 3000 rpm. Lambda sensor heating system voltage too high. Scania today presents its new generation buses for city and suburban operations. Scania set world-class standards for fuel economy, driveability; road … Next Prev. Various modifications Or max.) Out on the road this week, look out for more on this in the Dec issue of T&D which is a "V8 Special". An electrical break in the mass flow sensor circuit. Scania offers a wide choice of vehicles. Check for fuel in the tank and bleed the fuel system to remove air from it. If the engine is actually colder than the pre-programmed value indicates, it will idle more irregularly and be more difficult to start. While the use of thinner, more effective modern oils is a factor here, the improvements in advanced long-life oils in recent years are not sufficient on their own; the engine itself must also be developed to capitalise on the possibilities: “Raising the pressure and the power output requires that several comp­onents inside the engine, including gears, pistons, rings, cylinder heads and valves, are refined and reinforced,” says Lindh. High pressure In the event of a fault in one of the sensors, it may affect the electrical circuits of the other sensors. The Scania marine engines are renowned for industry-leading fuel efficiency irrespective of emission standard, and a given choice for anyone who seeks to optimise fuel economy without compromising performance. A fault is only recorded while the engine is running. The outside temperature sensor indicates a too high value or the temperature sensor before intake of air to the impeller of the turbocharger shows a too low value. Make sure the sensor is connected to the correct pin in the engine control unit connector (try changing the polarity). Scania Opticruise and Scania Retarder, as well as a selection of power take-offs, are available for all range-splitter gearboxes. Petrol tank. driver’s life subscribe today. If no fault is found, replace the charge air temperature sensor. The cylinder does not output the same power as the other cylinders for the following reason: The cause may be air in the fuel system, but in this case several cylinders are likely to be affected. If the torque reduction function is activated, the amount of fuel and the engine power output are reduced to 70%, and if the engine shutdown function is activated, the engine is switched off at programmed alarm levels. Measure the resistance between the wires and ground of the power supply. The ongoing development of Scania V8 engines by the company’s team of engineers continues into the 2020s, resulting in even more fuel-efficient engines suited for the most demanding transportation tasks. Check the turbocharger and its electric motor. With sales commencing in October 2020, the first version of the new gearboxes can be coupled with three of Scania’s four new Euro 6 V8s and two inline six engines. Diesel consumption Scania, , R560 -AdBlue-1,38 l/100km: 140.859 km and 1.937 l CO 2 emission:: 36 g/km: 140.859 km and 5.113 kg The mass flow sensor, oil pressure sensor and fuel temperature sensor have a common power supply.
