Title: G16E-GTS (ENGINE CONTROL): CAMSHAFT OIL CONTROL SOLENOID: INSPECTION; 2023 - 2025 MY GR Corolla [09/2022 -        ]

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)

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 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:

4.3 mm (0.169 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.
