DTC P1260 - P1267 FUEL INJECTOR ADJUSTMENT RESISTOR
DTC P1260 - P1267 FUEL INJECTOR ADJUSTMENT RESISTOR PFP:16600
Description EBS0123H
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 Value EBS0123I
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.
On Board Diagnosis Logic EBS0123J
The MI will not light up for these self-diagnoses.
