Inspection [09/2022 - ]: Procedure
WARNING: This page is about a different car, the 2025 Toyota GR Corolla, 2024 Toyota GR Corolla, and 2023 Toyota GR Corolla. However, it is still accessible from the selected car via links, so may be relevant.
- INSPECT CAMSHAFT 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 Component without harness connected
(Camshaft Timing Oil Control Solenoid Assembly)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.
- Measure the resistance according to the value(s) in the table below.
- Stroke Amount Inspection
- 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.NOTE:
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 - 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.
- 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.
- Check the resistance.
