Ignition Coil: Testing and Inspection

1. INSPECT POWER SOURCE LINE

(a) Disconnect the high4ension cord from ignition coil.

(b) Disconnect the ignition coil connectors.

(c) Turn the ignition switch ON.

(d) Using a voltmeter, measure the voltage between terminal 1 and body ground.

Voltage: Approx. 12V

2. INSPECT PRIMARY COIL RESISTANCE

Using an ohmmeter, measure the resistance between the positive (+) and negative (-) terminals.

Primary coil resistance (cold): 0.3 - 0.5 ohms

NOTE: Because is inside the coil, it is impossible to measure secondary cord resistance.

3. INSPECT IGNITION COIL GROUND

Using an ohmmeter, check that there is no continuity between the ignition coil terminal and body ground.

4. IF NECESSARY, REPLACE IGNITION COIL

Using a hexagon wrench 3 mm (0.12 in.), replace the ignition coil.

5. INSTALL IGNITION COIL WITH BRACKET

(a) Connect the ignition coil connector.

(b) Install the high-tension cords in shown in the illustration; No.5 and No.6 No.3 and No.4, and No.1 and No.2.

6. INSTALL IGNITION COIL COVER

(a) Remove the oil filler cap.

(b) Install the ignition coil cover with the five nuts.

(c) Install the oil filler cap.

7. INSTALL INTAKE AIR CONNECTOR

(a) Install the intake air connector.

(b) Install and tighten the two bolts.

(c) Tighten the clamp.

(d) Connect the air valve hose.

8. INSTALL PCV PIPE WITH HOSES

(a) Install the PCV pipe with hoses to throttle body and cylinder head covers.

(b) Install and tighten the two bolts.

(c) Connect the No.4 PCV hose.

(d) Install the oxygen sensor wire to the two PCV pipe clamps.

9. INSTALL ISC PIPE

(a) Install the ISC pipe with the two bolts.

(b) Connect the six hoses to ISC pipe.

10. CONNECT FOLLOWING CABLES:

(a) (A/T)
Throttle cable

(b) Accelerator cable

(c) Cruise control cable

11. CONNECT NO.1 AIR CLEANER HOSE
