2NZ-FE ENGINE CONTROL  CAMSHAFT OIL CONTROL VALVE  INSPECTION  


PROCEDURE

Hide 11101J 1.INSPECT CAMSHAFT TIMING OIL CONTROL VALVE ASSEMBLY

a.

Measure the resistance according to the value(s) in the table below.

Standard Resistance:
Tester Connection Condition Specified Condition
1 - 2 20°C (68°F) 6.9 to 7.9 Ω


If the result is not as specified, replace the camshaft timing oil control valve assembly.


b.

Check the operation.

(Camshaft Timing Oil Control Valve Assembly)
*b When Applied
*c When Cut Off
*d Spool Valve


Connect a battery positive (+) lead to terminal 1 and negative (-) lead to terminal 2, and check the movement of the spool valve.

OK:
Condition Specified Condition
Battery voltage applied Valve moves in left arrow direction shown in illustration
Battery voltage cut off Valve moves in right arrow direction shown in illustration


NOTICE:

Accumulation of foreign matter can cause minor pressure leaks. Minor pressure leaks will cause the camshaft to advance or retard, and this will cause a DTC to be stored.


If the result is not as specified, replace the camshaft timing oil control valve assembly.
