On-vehicle Inspection

Spark Test
1.
Remove the engine cover (A).

2.
Disconnect the ignition coil connectors (A).

When removing the ignition coil connector, pull the lock pin (A) and push the clip (B).

3.
Remove the ignition coils (A).

4.
Disconnect the injector connector or extension connector (A).

5.
Using a spark plug socket, remove the spark plug.
6.
Install the spark plug to the ignition coil.
7.
Ground the spark plug to the engine.

8.
Check if spark occurs while engine is being cranked.
To prevent fuel being injected from injectors while the engine is being cranked, disconnect the fuel pump connector.
Crank the engine for no more than 5 ~ 10 seconds.
9.
Inspect all the spark plugs.
10.
Using a spark plug socket, install the spark plug.
11.
Install the ignition coil.

Tightening torque :
9.8 ~ 11.8 N.m (1.0 ~ 1.2 kgf.m, 7.2 ~ 8.7 lb-ft)

When inserting ignition coil into the cylinder head cover for spark plug to be inserting ignition coil, the sealing cap of ignition coil must be mated totally with inner side of cylinder head.
12.
Reconnect the ignition coil connectors.
