2GR-FE IGNITION: IGNITION SYSTEM: ON-VEHICLE INSPECTION

NOTICE:
In this section, the terms "cold" and "hot" refer to the temperature of the coils. "Cold" means approximately -10°C (14°F) to 50°C (122°F). "HOT" means approximately 50°C (122°F) to 100°C (212°F).

1. INSPECT IGNITION COIL ASSEMBLY

(a) Check for DTCs DTC Check / Clear (from 12/2010).

NOTICE:
If any DTC is present, perform troubleshooting procedures for that DTC.

(b) Check that spark occurs.

(1) Remove the V-bank cover Removal (from 12/2010).

(2) Remove the intake air surge tank Removal (from 12/2010).

(3) Remove the ignition coils.

(4) Using a 16 mm (0.63 in.) plug wrench, remove the spark plugs.

(5) Install the spark plugs to each ignition coil, and connect the ignition coil connectors.

(6) Disconnect the 6 injector connectors.

(7) Ground the spark plugs.

(8) Check that spark occurs at each spark plug while the engine is being cranked.

NOTICE:
* Be sure to ground the spark plugs when checking them.
* If an ignition coil has been struck or dropped, replace it.
