DTC P1301 - P1304 FUEL INJECTOR ADJUSTMENT RESISTORPFP:16600
DescriptionEBS008XN
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 ValueEBS008XP
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 LogicEBS008XQ
DTC Confirmation ProcedureEBS008XR
WITH CONSULT-II
1. Turn ignition switch “ON” and wait at least 2 seconds.
2. Select “DATA MONITOR” mode with CONSULT-II.
3. Start engine and run it for at least 2 seconds at idle speed.
(If engine does not run, turn ignition switch to “START” for at
least 2 seconds.)
4. If DTC is detected, go toEC-779, "
Diagnostic Procedure".
