Tacoma 4WD L4-164.4 2693cc 2.7L DOHC (3RZ-FE) (1996)
Distributor: Testing and 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 (104°F) and
"Hot" is from 50°C (104°F) to 100°C (212°F).
1. DISCONNECT DISTRIBUTOR CONNECTOR.
2. REMOVE DISTRIBUTOR CAP.
3. REMOVE ROTOR.
4. REMOVE IGNITION COIL DUST COVER.
5. INSPECT PRIMARY COIL RESISTANCE.
-
Using an ohmmeter, measure the resistance between the positive (+) and negative (-) terminals.
Primary coil resistance:
Cold: 0.36 - 0.55 0hms
Hot: 0.45 - 0.85 0hms
-
If the resistance is not as specified, replace the ignition coil.
6. INSPECT SECONDARY COIL RESISTANCE.
-
Using an ohmmeter, measure the resistance between positive (+) and high-tension terminals.
Secondary coil resistance:
Cold: 9.0 - 15.4 k Ohms
Hot: 11.4 - 18.1 k Ohms
-
If the resistance is not as specified, replace the ignition coil.
7. INSPECT AIR GAP.
-
Using a feeler gauge, measure the air gap between the signal rotor and pickup coil projection.
Air gap: 0.2 - 0.4 mm (0.008 - 0.016 in)
-
If the air gap is not as specified, replace the distributor housing assembly.
