Fuel Injector Inspection
FUEL INJECTOR INSPECTION
WARNING: Fuel can ignite and cause serious injury or death, and damage. To prevent this, always make sure to follow the warnings and
cautions for each procedure when repairing or inspecting.
Fuel Injector Operation Inspection
Fuel injector (FP1, RP1) operation inspection
1. Warm up the engine and idle it.
2. Inspect the following PCM output wave pattern. (See PCM INSPECTION.) See: Computers and Control Systems/Testing and Inspection/Scan
Tool Testing and Procedures/PCM Inspection
-
PCM terminal 2M (FP1)
-
PCM terminal 2J (RP1)
3. If a normal condition of the PCM wave pattern cannot be verified, inspect the following and repair or replace the malfunctioning part.
Fuel injector (FP1)
-
Short circuit of the wiring harness, connector between fuel injector (FP1) ,terminal A and main relay terminal C
-
Short circuit of the wiring harness between PCM terminal 2M and fuel injector (FP1) terminal B
