If slight poor power occurs while driving, Inspect current data that can change the fuel injection quantity in detail. Items that affect the fuel injection quantity and compensation must be inspected. There are Normal IQA(Injector Quantity Adjustment) input, fuel temperature and engine coolant temperature sensor, rail pressure sensor, gear position selected…etc in items.
Case 1 : In case of IQA(Injector Quantity Adjustment) input inspection.
Go to "Injector IQA inspection" procedure.
Case 2 : In case of "fuel temperature sensor" and "engine coolant temperature sensor" inspection.
Go to "FTS (Fuel Temperature Sensor) & ECTS (Engine Coolant Temperature Sensor) inspection" procedure.
Case 3 : In case of gear position and neutral position inspection.
Go to "Switch signal(Gear position) inspection" procedure.
Case 4 : In case of rail pressure sensor inspection.
Go to "RPS (Rail Pressure Sensor) inspection" procedure.
