6F-8 IGNITION SYSTEM
DISTRIBUTOR
DISTRIBUTOR CAP AND ROTOR
INSPECTION
Check cap and rotor for crack and their terminals for corrosion and
wear. Replace as necessary.
SIGNAL ROTOR AIR GAP
INSPECTION
1) Remove distributor cap and rotor.
2) Using thickness gauge, measure air gap, between signal rotor
tooth and CMP sensor (generator).
Signal rotor air gap “a”: About 0.2 mm (about 0.008 in.)
3) If gap is out of specification, loose CMP sensor (signal genera-
tor) securing screws. Using blade (–) screw driver, move CMP
sensor (generator) and adjust gap to specification. After adjust-
ment, tighten securing screws and recheck gap.
NOTE:
Check to make sure that CMP sensor (signal generator)
tooth is free from any metal particles.
4) Install distributor cap and rotor.
CMP SENSOR (PICKUP COIL) RESISTANCE
INSPECTION
1) Disconnect distributor lead coupler.
2) Measure resistance of pickup coil by using ohmmeter.
3) If resistance is out of specification, replace CMP sensor (signal
generator) as follows.
Pickup coil resistance:
185 – 275 Ω at – 10_C (14_F) – 50_C (122_F)
240 – 325 Ω at 50_C (122_F) – 100_C (212_F)
4) Remove distributor cap and rotor.
5) Remove CMP sensor (signal generator) securing screws and
lead wire clamp screws.
6) Replace CMP sensor (signal generator).
7) Adjust signal rotor air gap to specifications as previously out-
lined.
8) Install rotor, distributor cap seal and cap.
