P0265 Cylinder 2 Injector Circuit High - General Information

Component Location





General Description

Injectors jet out high pressure fuel caculated by ECM to each cyliders. Direct and separated injections improve fuel efficiency and engine power.
The IDB(injector driver box) controls injector operation. If the IDB receives signal for injector operation from ECM, IDB boosts the voltage and uses current by voltage difference between HIGH and LOW side of injector circuit as injector operating current.

DTC Description

f there is short to battery in injector #2,5 High/Low side circuit (IDB ~ injector #2,5), ECM sets DTC P0265.
