Distributor Assembly:






DISASSEMBLY, TEST AND REASSEMBLY

1. Rotor from distributor housing.

2. Ignition coil dust cover and gasket from distributor housing.

3. Two nuts and four wires from the ignition coil terminals.

4. Four screws and ignition coil from distributor housing.

5. Three screws and three wires from the igniter terminals.

6. Two screws and igniter from distributor housing.


Distributor Connectors:






7. Two connectors from the harness retainer.

Measure

Tool Required:

J39200 Digital Multimeter

NOTICE: The term "cold" refers to temperature ranging from -10° C (14° F) to 50°C (104° F). The term "hot" refers to temperature ranging from 50° C (104° F) to 100° C (212° F).


Measuring Camshaft Position Sensor Resistance:






1. The resistance of distributor connector C1 when cold, between terminals 3 and 6, using a J39200. If the camshaft position (CMP) sensor resistance is not between 185 and 275 ohms, replace the distributor housing.

2. The resistance of distributor connector C1 when cold, between terminals 2 and 5. using a J39200. If the CMP sensor resistance is not between 370 and 550 ohms. replace the distributor housing.

3. The resistance of distributor connector C1 when hot, between terminals 3 and 6, using a J39200. If the CMP sensor resistance is not between 240 and 325 ohms. replace the distributor housing.

4. The resistance of distributor connector C1 when hot, between terminals 2 and 5. using a J39200. If the CMP sensor resistance is nor between 475 and 650 ohms, replace the distributor housing.


Measuring Air Gap:






5. Air gap between the signal rotor and camshaft position (CMP) sensor. If the air gap is not between 0.2 - 0.4 mm (0.008 - 0.016 inch), replace the distributor housing.

Inspect


Inspecting The Distributor Shaft:






1. Shaft for roughness or wear. If it feels rough or worn, replace the distributor housing assembly.

2. Distributor cap and rotor for cracks, terminal corrosion and wear; replace as necessary.

Install or Connect

1. Noise suppressor condenser to distributor housing; secure with one screw.

2. Distributor wire to distributor housing.

3. Harness retainer to distributor housing; secure with one screw.

4. Two connectors to harness retainer.

5. Igniter to distributor housing; secure with two screws.

6. Three wires to igniter terminals; secure with three screws.

7. Ignition coil to distributor housing; secure with four screws.

8. Four wires to ignition coil terminals; secure with two nuts.

NOTICE: When connecting the wires to the ignition coil, insert them properly into their grooves found on the side of the ignition coil and make sure the wires do not come in contact with the signal rotor or distributor housing.

Tighten

^ Ignition coil terminal nuts to 8 Nm (71 lb.in.).

9. Ignition coil dust cover and new gasket to distributor housing.

10. Rotor to distributor housing.

  • β€’ You smell fuel, burning insulation, or see smoke.
  • β€’ Brakes feel soft, pull hard to one side, or make grinding noises.
  • β€’ The engine overheats, stalls repeatedly, or misfires under load.
  • β€’ You are missing required tools, torque specs, or safe lifting equipment.
  • β€’ You are not confident in the next step or safety outcome.
