ENGINE 273 MPFI 259 ENGINE THROTTLE POSITION SENSOR Signal Connector ECU Pin No. Pin No. Type: DKG-V Location This sensor is a part of Integrated Throttle Body which is fitted on inlet manifold upstream side. Throttle lever shaft is extended to a crank lever which operates the sensor (varies the circuit resistance). Pin Details: Throttle Position Sensor 1 10 Throttle Position Sensor Supply 2 6 Throttle Position Sensor Ground 3 31(A) (Lambda SensorGround) Pin Configuration: Working Principle The throttle-valve sensor is potentiometer with linear characteristic curve. The rotor arm, which is connected with the throttle-valve shaft, drives with its wipers over the related resistance tracks. Therewith the angle of rotation of the throttle-valve is transferred into a thereto proportional voltage U A /U V . The throttle-valve sensor does not possess a return-spring. Where, U A = O/P Voltage U V =i/p Voltage Installation Details The sensor is suitable for mounting in the Engine bay. Permissible tightening torque for fixing screws: 1.5 – 2.5 Nm Storage Conditions Throttle-valve sensors have to be stored at dry place, which should be dust-free and free from silicon area. During transport or mounting of the component, the connector and the internal space of the sensor must not be contaminated by reactive, liquids or water. Storage Temperature -10°C to 80°C Relative Humidity 20 to 80%
