Injector 2 connector not connected or loose 2. Wiring harness connector fault 3. High side short to low side 4. Faulty injector 5. Faulty ECU 1. Idle speed raised 2. Reduced vehicle performance 3. Vehicle Misfire possible 4. Vehicle might not start 5. NOx, DPF regeneration inhibited. Component Details: The Solenoid Valve Injectors are used to inject the desired fuel quantity based on the engine operating conditions into the combustion chamber. They are mounted at the cylinder head above the combustion chamber. Checkpoints: 4. Check wiring harness related to injector circuit 5. Check injector for any damage to the connector pins 6. Check Battery Voltage Trouble Shooting Steps: Sr. No. Steps Specifications Step 1 Check the Battery voltage. If Voltage out of Range, correct battery 6 – 16 V Step 2 Check if injector connector is fitted properly. Rectify if necessary Step 3 Check for pin back outs on injector and ECU connector. Rectify if necessary Step 4 Check for wiring harness circuit continuity. Rectify if necessary Refer circuit diagram Step 5 Check injector coil electrical continuity Replace injector if continuity not present Step 6 Replace ECU Circuit Schematic Diagram: Component Location and Image:
