Inspection [12/2015 - 08/2016]: Procedure
WARNING: This page is about a different car, the 2016 Toyota Sienna. However, it is still accessible from the selected car via links, so may be relevant.
- INSPECT CAMSHAFT TIMING OIL CONTROL VALVE ASSEMBLY
- Measure the resistance according to the value(s) in the table below.TEXT IN ILLUSTRATION
*a Component without harness connected
(Camshaft Timing Oil Control Valve Assembly)Standard Resistance
Tester Connection Condition Specified Condition 1 (+B) - 2 (GND) 20°C (68°F) 6.9 to 7.9 Ω If the result is not as specified, replace the oil control valve.
- Check the operation.TEXT IN ILLUSTRATION
*1 Spool Valve *2 Battery *a Component without harness connected
(Camshaft Timing Oil Control Valve Assembly)- Connect a battery positive (+) lead to terminal 1 and negative (-) lead to terminal 2, and check the movement of the spool valve.
OK
Tester Connection Condition Specified Condition 1 - 2 Battery positive (+) voltage is applied Valve moves in direction of left arrow shown in the illustration Battery positive (+) voltage is cut off Valve moves in direction of right arrow shown in the illustration If the result is not as specified, replace the oil control valve.
NOTE:Accumulation of foreign matter can cause minor pressure leaks. Minor pressure leaks in the intake side oil control valve will cause the intake camshaft to advance. Minor pressure leaks in the exhaust side oil control valve will cause the exhaust camshaft to retard. The inappropriate camshaft timing that results from these leaks will cause a DTC to be set.
- Connect a battery positive (+) lead to terminal 1 and negative (-) lead to terminal 2, and check the movement of the spool valve.
- Measure the resistance according to the value(s) in the table below.
