Toyota Sienna Service Manual: Inspection
1. INSPECT CAMSHAFT TIMING OIL CONTROL VALVE ASSEMBLY
- Resistance inspection
- Using an ohmmeter, measure the resistance
between the terminals.
Resistance: 6.9 to 7.9 Ω at 20C (68F) If necessary, replace the camshaft timing oil control valve assembly.
- Movement inspection
- Connect the positive (+) lead from the battery to terminal 1 and connect the negative (-) lead to terminal 2, and check the movement of the valve.
NOTICE: Confirm that the valve moves freely and does not stick in any position.
If necessary, replace the camshaft timing oil control valve assembly.
HINT: Accumulation of foreign objects causes subtle pressure leaks. The subtle pressure leaks will cause the cam to advance, and this will cause a DTC to be set.
