All service procedures are broken down into detailed steps, listed in their recommended sequence. The manual uses both photographs and drawings to help locate and itemize components. The table of Contents on the preceding pages is your best tool for finding the service procedure you need. Be certain to observe all Safety information included in these pages.\u003cbr\u003eA schematic of each of the major engine systems is provided at the beginning of the section of the manual devoted to troubleshooting and repairing that particular system.\u003cbr\u003eBasic safety precautions are list in the Safety section of the Service Manual. Additional safety precautions are list in the Safety section of the owner\/operation\/maintenance publication. Specific safety warnings for all these publications are provided in the description of operations where hazards exist. WARNING labels have also been put on the product to provide instructions and to identify specific hazards.\u003cbr\u003eInstruction Extracts\u003cbr\u003eIAT and MAF Sensors\u003cbr\u003eThe IAT and MAF sensors are installed on the intake duct. The IAT sensor detects the intake air temperature, and the MAF sensor detects the intake airflow amount. In the IAT sensor, the thermistor changes the resistance value according to temperature changes. The resistance characteristics are comprised of a low resistance value when the intake air temperature is high and a high resistance value when the intake air temperature is low.\u003cbr\u003eThe ECM applies 5 V to the IAT sensor through the pull-up resistor and calculates the intake air temperature from changes in the voltage. This value is used in various control mechanisms, such as fuel injection control.\u003cbr\u003eThe MAF sensor detects the intake airflow amount that is sent to the engine. Based on this information from the MAF sensor, the ECM monitors the operation conditions of the engine to calculate the fuel supply.\u003cbr\u003eThe ECM recognizes information such as a large amount of air entry indicating acceleration or high-load state, and a small amount of air entry indicating deceleration or an idling state.\u003cbr\u003eIntake Throttle Valve\u003cbr\u003eThe intake throttle valve is installed on the intake duct. It is driven by the intake throttle motor, and the intake throttle position sensor detects the valve position. Since the intake throttle valve raises the engine exhaust temperature during DPD regeneration, it controls the intake air amount.","brand":"Uploader","offers":[{"title":"Default Title","offer_id":53593322946891,"sku":null,"price":60.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0978\/2519\/4315\/files\/1-70_ac8614f2-9670-43c7-bafc-2d99a79e974e.png?v=1760374778","url":"https:\/\/manualbull.com\/products\/doosan-dx490lc-3-and-dx530lc-3-excavator-service-manual-workshop-guide","provider":"ManualBull","version":"1.0","type":"link"}
