    (EGR system) in intake manifold can lead to a damage. To check operation of electronic throttle control it is necessary to use dedicated tester. To force throttle movement it is required to apply specific control signals. DTA-1 tester is designed for just such tasks.

  • Page 4: Function And Operation Of Diesel Air Throttle

    Engine Controller (ECU) is responsible for generation of required signals. To diagnose this kind of throttle an appropriate tester is needed, such as DTA-1. Air throttle in diesel engine is located on the intake manifold, before exhaust gas intake from EGR valve.
  • Page 5 DTA-1 tester user manual Figure 2.1 Location of throttle in diesel engine (Source: Pierburg) Principle of throttle operation is depicted in Figure 2.2. For exhaust recirculation to get desired effect it is needed to provide the necessary amount of exhaust gases. Exhaust can enter intake manifold if |EGR valve is open and exhaust pressure exceeds intake air pressure.

    DTA-1 tester user manual The values in Table 8.2 were determined on the basis of numerous test conducted by DeltaTech Electronics company. Nevertheless these are only demonstrative values that can be useful while diagnosing air throttles. After pressing the back button, the device returns to test selection.
  • Page 19 DTA-1 tester user manual Figure 9.1 Throttle inside: A – new throttle, B – unit contaminated by oil (Source: Pierburg) Engine oil also leads to damage of flap position sensor inside actuator controller. This is due to insufficient sealing between throttle body and the shaft moving the flap. This results in engine oil penetrating the controller and causing whole parts (circuit board, DC motor, position sensor) to submerge in oil.
