SFI SYSTEM (1MZ–FE)
1.
INTAKE AIR FLOW METER SUB–ASSY
(a)
Output voltage inspection.
(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 volt-
age fluctuates.
(b)
Resistance inspection.
(1)
Using an ohmmeter, measure the resistance be-
tween terminals 4 (THA) and 5 (E2).
Resistance:
–20_C (–4_F) 13.6 – 18.4 kΩ
20_C (68_F) 2.21 – 2.69 kΩ
60_C (140_F) 0.493 – 0.667 kΩ
