Lexus ES (XZ10) Service Manual / Engine & Hybrid System / A25a-fxs (engine Control) / Camshaft Oil Control Solenoid / Inspection

INSPECTION

PROCEDURE

1. INSPECT CAM TIMING OIL CONTROL SOLENOID ASSEMBLY

(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)

6.3 to 7.3 Ω

20 °C (68 °F)

6.9 to 7.9 Ω

40 °C (104 °F)

7.4 to 8.6 Ω

If the result is not as specified, replace the cam timing oil control solenoid assembly.

(Cam Timing Oil Control Solenoid Assembly)

(b) Stroke Amount Inspection

(1) Using vernier calipers, measure length (A) and (B) with the shaft of the cam timing oil control solenoid assembly set in the respective positions shown in the illustration.

NOTICE:

Do not apply auxiliary battery voltage to the terminals of the cam 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:

4.3 mm (0.169 in.) or more

HINT:

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

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