On-Vehicle Inspection

DISTRIBUTOR INSPECTION

NOTICE: "Cold" and "Hot" in the following sentences express the temperature of the coils themselves.
"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).

1. REMOVE DISTRIBUTOR CAP WITHOUT DISCONNECTING HIGH-TENSION CORDS
2. REMOVE ROTOR
3. INSPECT AIR GAP

Air Gap Measurement:

- Using SST (G1 and G2 pickups) and a feeler gauge (NE pickup), measure the air gap between the signal rotor and pickup coil projection. SST 09240-00020 for G1 and G2 pickups.

Air gap: 0.2 - 0.5 mm (0.008 - 0.020 in.)

- If the air gap is not as specified, replace the distributor housing assembly.
4. DISCONNECT DISTRIBUTOR CONNECTOR
5. INSPECT SIGNAL GENERATOR (PICKUP COIL) RESISTANCE

Ohmmeter Connection:

- Using an ohmmeter, measure the resistance between terminals.

Pickup coil resistance (Cold):
G1 and G(-): 126-200 Ohms
G2 and G(-): 125-200 Ohms
NE and G(-): 155-250 Ohms

Pickup coil resistance (Hot):
G1 and G(-): 160-235 Ohms
G2 and G(-): 160-235 Ohms
NE and G(-): 190-290 Ohms

- If the resistance is not as specified, replace the distributor housing assembly.
6. RECONNECT DISTRIBUTOR CONNECTOR
7. REINSTALL ROTOR
8. REINSTALL DISTRIBUTOR CAP
