Inspection [12/2023 - ]: Procedure
WARNING: This page is about a different car, the 2024 Lexus TX 550h+. However, it is still accessible from the selected car via links, so may be relevant.
- INSPECT CAM TIMING OIL CONTROL SOLENOID ASSEMBLY
HINT:
Use the same procedure for the intake side and exhaust side.
- Check the resistance.
- Measure the resistance according to the value(s) in the table below.
*A for Intake Side *B for Exhaust Side *a Component without harness connected
(Cam Timing Oil Control Solenoid Assembly)Standard Resistance
Tester Connection Condition Specified Condition Result 1 (+R) - 2 (-R) 0°C (32°F) 5.3 to 6.3 Ω Ω 1 (+R) - 2 (-R) 20°C (68°F) 5.8 to 6.8 Ω Ω 1 (+R) - 2 (-R) 40°C (104°F) 6.2 to 7.4 Ω Ω 1 (+) - 2 (-) 0°C (32°F) 5.3 to 6.3 Ω Ω 1 (+) - 2 (-) 20°C (68°F) 5.8 to 6.8 Ω Ω 1 (+) - 2 (-) 40°C (104°F) 6.2 to 7.4 Ω Ω If the result is not as specified, replace the cam timing oil control solenoid assembly.
- Measure the resistance according to the value(s) in the table below.
- Stroke Amount Inspection
- Using a vernier caliper, 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.NOTE:
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 - Calculate the stroke amount based on the difference of length (A) and (B).
Standard
Specified Condition Result 6.5 mm or higher
0.256 in. or highermm
in.HINT:
Stroke amount = length (A) - length (B)
If the value is not as specified, replace the cam timing oil control solenoid assembly.
- Using a vernier caliper, 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.
- Check the resistance.
