to reduce TORQUE vibration

Why Injector BACK LEAK test is done ?

to identify suspect injector from the set of injectors only

to find out whether the individual injector is good or bad

to measure fuel consumption

to check whether IQA is correct or not

What is a ‘P’ codes ?

‘P’ code is Powertrain Code related to engine, transmission and emissions systems

‘P’ code is Powertrain Code related to engine, and emissions systems

‘P’ code is Powertrain Code related to engine only

‘P’ code is Powertrain Code related to emissions system only

(a)

18.

Related to IQA, which statements are correct ?

IQA is a code related to the calibrated flow rate of the injector.

IQA code is fed into the engine ECU with cylinder number during engine assembly.

IQA code enables the ECU to correct the injection quantity to compensate for manufacturing tolerances.

IQA code enables PILOT injection quantity correction
