Inspection

INSPECTION

PROCEDURE

1. INSPECT CAMSHAFT TIMING OIL CONTROL SOLENOID ASSEMBLY

HINT:

Use the same procedure for the intake side and exhaust side.

(a) Check the resistance.

(1) Measure the resistance according to the value(s) in the table below. Standard Resistance: Tester Connection Condition Specified Condition 1 - 2 0 °C (32 °F) 5.3 to 6.3 Ω 20 °C (68 °F) 5.8 to 6.8 Ω 40 °C (104 °F) 6.2 to 7.4 Ω If the result is not as specified, replace the camshaft timing oil control solenoid assembly.

*a Component without harness connected (Camshaft Timing Oil Control Solenoid Assembly)

(b) Stroke Amount Inspection

(1) Using vernier calipers, measure length (A) and (B) with the shaft of the camshaft timing oil control solenoid assembly set in the respective positions shown in the illustration. NOTICE: Do not apply battery voltage to the terminals of the camshaft timing oil control solenoid assembly. HINT: If the shaft does not extend under its own weight, extend the shaft with your fingers.

*a Shaft Side Facing Down *b Shaft Side Facing Up *c Shaft

(2) Calculate the stroke amount based on the difference of length (A) and (B).

Standard:

6.5 mm (0.256 in.) or more

HINT:

Stroke amount = length (A) - length (B)

If the value is not as specified, replace the camshaft timing oil control solenoid assembly.

On-vehicle Inspection

ON-VEHICLE INSPECTION

PROCEDURE

1. INSPECT CAMSHAFT TIMING OIL CONTROL SOLENOID ASSEMBLY

(a) Connect the Techstream to the DLC3.

(b) Start the engine.

(c) Turn the Techstream on.

(d) Inspect the camshaft timing oil control solenoid assembly (for intake side).

(1) Enter the following menus: Powertrain / Engine / Active Test / Control the Intake VVT OCV Duty Ratio Bank 1 or Control the Intake VVT OCV Duty Ratio Bank 2 / Data List / Intake VVT Change Angle Bank 1 or Intake VVT Change Angle Bank 2.
