Short to battery + or an open circuit in the air intake temperature sensor circuit. Small leakage in the high pressure section of the fuel system. If the operating time since the generation of the fault code exceeds 10 hours, empty the EGR cooler, as there is a danger of condensation in the air-cooled EGR cooler after the EGR system is turned off. For more news, views and reviews on all aspects of the truck With the sensor disconnected, the voltage should be approximately 5 V. Check the air intake temperature sensor T126 and its connectors and wiring. SCANIA G460 TRUCK Mileage. If you have any questions, please contact us. Check supply pressure, fuel metering inlet valve, high pressure pump and check for leaks. The Scania Driver Support service helps drivers to learn and retain fuel-saving skills. If there is only a slight deviation in the supply pressure, this may mean that the bypass valve is stuck. Check fuses. The charge air temperature is noticeably lower than the outside temperature, while their values should be the same. Clear the fault code. Ensure that the pipeline between the turbocharger and the air filter is intact and not leaking. Scania's first Euro 4 engines are already on the market. Troubleshooting for air intake temperature sensor. Torque. There is a deterioration in the cooling efficiency provided by the charge-air cooler. Check the system gas supply and injectors.
