Drive the vehicle certain conditions for checking poor power/acceleration.
Monitor change of current data when the symptom happens.
■ Reference data
Fig.1) Normal current data while accelerating.
This current data is nothing but an example at certain condition. Thus, the real current data could be different from this example.
Is the displayed current data normal?
 | ▶ Go to "Intake air inspection" procedure. |
 | ▶ If it is the following subject, check/repair folding/blocked/leak of the low fuel line(fuel tank→high pressure fuel pump) and fuel filter blocked. • The rail pressure is unstable at idle or accelerating. • While accelerating "Poor acceleration"/"Engine stalling" happens without the rail pressure rises. ▶ Go to "Injector" inspection procedure. ▶ Go to "RPS" inspection procedure. ▶ Check/repair FPRV.(high pressure pump) |
