1.2L REVOTRON ENGINE 201 SENSOR STANDALONE DIAGNOSIS Connector details: Injector 1 1. ECU pin M2H2 : signal 2. supply voltage - 12V Injector 2 1. ECU pin M2G3 : signal 2. supply voltage - 12V Injector 3 1. ECU pin M2G2 : signal 2. supply voltage - 12V Use multimeter to check coil resistance which should be 12.25ohms ± 0.5ohms V. ELECTRONIC THROTTLE BODY COMPONENT DETAILS A DC motor drive is used to move the throttle valve over the complete movement range. The DC motor is directly controlled by the ECU of the Diesel engine. Throttle Valve H-bridge driver of EMS ECU provides bidirectional control with active recirculation and over current detection. COMPONENT LOCATION The throttle position sensor is mounted on intake manifold upstream side. PRELIMINARY CHECKS 1. Please check whether dust/mud/any particle is blocking throttle valve. 2. Please check whether the throttle valve is stuck closed. 3. Please check for any throttle body related faults and rectify those faults by following their rectification procedure.
