DTC P1268 - P1271 FUEL INJECTOR
DTC P1268 - P1271 FUEL INJECTOR PFP:16600
Component Description BBS0023V
The fuel injector is a small, precise solenoid valve. When the ECM
supplies a ground to the fuel injector circuit, the coil in the fuel injec-
tor is energized. The energized coil pulls the needle valve back and
allows fuel to flow through the fuel injector into the cylinder. The
amount of fuel injected depends upon the injection pulse duration.
Pulse duration is the length of time the fuel injector remains open.
The ECM controls the injection pulse duration based on engine fuel
needs.
CONSULT-II Reference Value in Data Monitor Mode BBS0023W
