Diagnostic Steps:

1

Measure VVT solenoid valve resistance.

(a) Rotated ignition switch to "OFF" position .

(b) Disconnect electronic Anti-theft coil harness connector IP25.

(c) Disconnect engine anti-theft module wire harness connector IP24.

(d) Inspect EAS Coil and engine anti-theft module harness connector.

onfirm whether the harness connector is well inserted and the connector harness breaks off.
