Description
Slow reaction of intake VVT
Open circuit of the VVT intake
control valve circuit
The intake VVT is not in the
default location when starting
Short circuit to ground of the
VVT intake control valve circuit
Short circuit to power supply of
the VVT intake control valve cir-
cuit
Setting Conditions (Control
• Short to ground or open circuit
• Short circuit to power supply
• Intake VVT hydraulic control valve circuits consist
of the following:
• Supply voltage: main relay provides reference volt-
age to terminal 2 of intake control valve wiring har-
ness connector E02 through terminal 45 of wiring
harness connector C01 fuse EF23.
• ECM control ground circuit: ECM positions the ter-
minal 1 on intake control valve wiring harness con-
nector E02 to low electric potential through
terminal 48 of ECM wiring harness connector E01.
Strategy)
Details/Results/Actions
A. Inspect the intake control valve wiring harness
connector E02 for loose or poor contact.
B. Check if the intake control valve is properly
installed.
Is it normal?
