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.
Symptom | Inspection procedure | |
Case1 | ● IQA (Injector Quantity Adjustment) input inspection. | ● Go to "IQA inspection" |
Case2 | ● "Fuel temperature sensor" and "engine coolant temperature sensor" inspection. | ● Go to "FTS (Fuel Temperature Sensor) & ECTS (Engine Coolant Temperature Sensor) inspection" |
Case3 | ● Gear position and neutral position inspection. | ● "Gear position (Switch signal) inspection" |
Case4 | ● Rail pressure sensor inspection. | ● "RPS (Rail Pressure Sensor) inspection" |
