INSPECTION AND ADJUSTMENT - Distributo r
DISTRIBUTOR (G AND NE SIGNALS
)
OBJECTIVE
. To learn the procedure for inspecting the distributor (G and NE signals) .
PREPARATIONS
:• Ohmmeter ( also called "circuit tester" or "multi-tester" )
• Feeler gauge
APPLICABLE ENGINE : 4A-FE* (Sep ., 1989 )
*Except Carina II (AT 171) with lean mixture senso r
1 . INSPECT AIR GA P
Using a feeler gauge, measure the gap between the
signal timing rotor and the pickup coil projection .
Air gap : 0 .2 mm (
0 .008 in .) or mor e
If the air gap is not as specified, replace the distributor
housing .
2 . INSPECT SIGNAL GENERATOR
(PICKUP COIL)
RESISTANC E
Using an ohmmeter, measure the resistance between
the terminals (G1 and G G, NE and G 6)
.
Pickup coil resistance ( cold)
: 185 - 265 S 2
If the resistance is not as specified, replace the
distributor housing .
