(a) Turn the ignition switch to "OFF" position.
(b) Disconnect VVT solenoid valve wiring harness connector
EN10.
(c) Disconnect ECM harness connector EN01.
(d) Use multimeter to measure the resistance between VVT
solenoid valve wiring harness connector EN10 terminal No.
2 and ECM harness connector EN01 terminal No.2. For the
Standard Value. Refer to the table below.
(e) Use multimeter to measure the resistance between VVT
solenoid valve wiring harness connector EN10 terminal No.
2 and the ground. For the Standard Value. Refer to the table
below.
(f) Turn the ignition switch to "ON" position, (Note: At this time
EN01 and EN10 connectors must be disconnected.) Use
multimeter to measure the voltage between the VVT solenoid
valve wiring harness connector EN10 No.2 terminal and the
ground. For the Standard Value. Refer to the table below.
