DTC P1260 - P1267 FUEL INJECTOR ADJUSTMENT RESISTORPFP:16600
DescriptionEBS011D8
The fuel injector adjustment resistor is built into the fuel injector. The resistance is constant and individual.
ECM uses the individual resistance to determine the fuel injection pulse.
ECM Terminals and Reference ValueEBS011D9
Specification data are reference values and are measured between each terminal and ground.
CAUTION:
Do not use ECM ground terminals when measuring input/output voltage. Doing so may result in dam-
age to the ECM's transistor. Use a ground other than ECM terminals, such as the ground.
