(a) Check the output voltage.

(1) Apply battery voltage across terminals 1 (+B) and 2 (E2G).

(2) Using a voltmeter, connect the positive (+) tester probe to terminal VG, and negative (-) tester probe to terminal E2G.

(3) Blow air into the MAF meter, and check that the voltage fluctuates.

(b) Measure the resistance between terminals 4 (THA) and



Specified Condition

-20« (-49)

13.6 to 18.4 k£2

20« (68«)

2.21 to 2.69 kil

60« (140«)

0.493 to 0.667 kil

If the result is not as specified, replace the MAF meter. 2. INSPECT CAMSHAFT TIMING OIL CONTROL VALVE ASSY

(a) Measure the resistance between the terminals. Standard: 6.9 to 7.9 Q, at 20tC (689)

If the result is not as specified, replace the OCV assy.

(b) Connect the battery's positive (+) lead to terminal 1 and negative (-) lead to terminal 2, and check the movement of the valve. NOTICE:

Confirm that the valve moves freely and does not become stuck in any position.

If necessary, replace the OCV assy. HINT:

If the valve cannot return properly because of foreign matter, a small pressure leak in the advanced direction may occur and a DTC will be output.
