Ignition System (engine Electrical System (g6ea-gsl 2.7)) Hyundai Santa Fe II

DESCRIPTION

Ignition timing is controlled by the electronic control ignition timing system. The standard reference ignition timing data for the engine operating conditions are preprogrammed in the memory of the ECM (Engine Control Module).

The engine operating conditions (speed, load, warm-up condition, etc.) are detected by the various sensors. Based on these sensor signals and the ignition timing data, signals to interrupt the primary current are sent to the ECM. The ignition coil is activated, and timing is controlled.

Scheme 1

Scheme 2

Scheme 3

1. Remove the ignition coil connector (A). NOTE: Disconnect the ignition coil connector while pulling up the connector lock.
2. Remove the ignition coil.
3. Using a spark plug socket, remove the spark plug.
4. Install the spark plug to the ignition coil.
5. Ground the spark plug to the engine.
6. Check is spark occurs while engine is being cranked. NOTE: To prevent fuel being injected from injectors while the engine is being cranked, remove the fuel pump (A) relay from the fuse box. Crank the engine for no more than 5 ~ 10 seconds.
7. Inspect all the spark plugs.
8. Using a spark plug socket, install the spark plug.
9. Install the ignition coil.
10. Reconnect the ignition coil connector.

Scheme 5

1. Inspect the electrodes (A) and ceramic insulator (B). INSPECTION OF ELECTRODES INSPECTION OF ELECTRODES Condition Dark deposits White deposits Description Fuel mixture too rich Low air intake Fuel mixture too lean Advanced ignition timing Insufficient plug tightening torque
2. Check the electrode gap (A). Standard : 1.0 ~ 1.1 mm (0.0394 ~ 0.0433 in.)

Scheme 6

1. Measure the primary coil resistance between terminals (+) and (-). Standard : 00715 ± 0.015ohms NOTE: Measure the resistance between the terminals No.1 and No.3.

Scheme 7

1. Remove the engine cover.
2. Remove the ignition coil connector (A).
3. Remove the ignition coil.
4. Installation is the reverse of removal.

Scheme 8

1. Remove the ignition coil connector (A).
2. Remove the ignition coil.
3. Using a spark plug socket, remove the spark plug. CAUTION: Be careful that no contaminates enter through the spark plug holes..
4. When replacing the spark plug, always use the long reach type spark plug. Do not use a short reach type. Color Marking (Tip). [2.7L] Unleaded : Yellow Marking Leaded : Green Marking [Others] Marking Color is different or does not exist Length (Tip-Tip / PT Length). 2.7L: 83.2mm/ 26.5mm [Others] The length is different from the specification above.
