INSPECTION PROCEDURE

1  Check resistance of each pickup coils in distributor.

P  Disconnect distributor connector.

C  Measure resistance between each terminal shown in the table below.

OK
                        Resistance
G1 pickup coil
(G1–G⁻±)    Cold    125 ~ 200 Ω
                Hot     160 ~ 235 Ω
G2 pickup coil
(G2–G⁻±)    Cold    125 ~ 200 Ω
                Hot     160 ~ 235 Ω
NE pickup coil
(NE–G⁻±)    Cold    155 ~ 250 Ω
                Hot     190 ~ 290 Ω

"Cold" is from — 10°C (14°F) to 50°C (122°F)
and "Hot" is from 50°C (122°F) to 100°C (212°F).

• During cranking or idling, check waveforms between terminals G1, G2, NE and G ± of engine control module
HINT: The correct waveforms are as shown.

OK                 NG  Replace Distributor

2  Check for open and short in harness and connector between engine control module and distributor (See page IN–30).

OK                 NG  Repair or replace harness or connector
