Distributor (G And Ne Signals) - Toyota COMPUTER-CONTROLLED SYSTEM Training Manual

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 GAP
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 S2
If the resistance is not as specified, replace the
distributor housing .
