Ignition System: Other Mitsubishi Outlander II

KNOCK CONTROL SYSTEM CHECK

Check the knock sensor circuit if diagnostic trouble code, No. P0326, P0327, P0328, P0331, P0332 or P0333 is shown. Refer to DIAGNOSTIC TROUBLE CODE CHART .

IGNITION COIL CHECK

Note. It is impossible to carry out an easy check using a circuit tester because a diode and so on are integrated into the inside circuit of this ignition coil. Accordingly, check the ignition coil in the following procedure.

1. Make sure the diagnosis codes are not stored using M.U.T.- III. If stored, record the code No. Carry out the troubleshooting for the stored codes and solve the problems even if not related to the ignition.
2. Disconnect the injector connectors on all of the cylinders.
3. Disconnect the ignition coil connector.
4. Remove the ignition coil and install a new spark plug to the ignition coil.
5. Connect the ignition coil connector.
6. Ground the side electrode of the spark plug and crank the engine.
7. Check that spark is produced between the electrodes of the spark plug.
8. If the spark plug has weak spark or no spark, carry out the same check using a new ignition coil. If there are strong spark on this check with a new ignition coil, it becomes clear there is a problem with the ignition coil. Replace the ignition coil with a new one. If there is no spark on this check with a new ignition coil, there is probably a problem with the ignition circuit. Check the ignition circuit.
9. Using M.U.T.-III, make sure whether the diagnosis codes are stored due to the check, or not. Except the codes stored in Step 1 , clear the codes all together if they are present. And then, carry out the troubleshooting about the codes recorded.

Scheme 3

1. Remove the spark plug and connect to the ignition coil.
2. Ground the spark plug outer electrode (body), and crank the engine. Check that there is an electrical discharge between the electrodes at this time.

Scheme 4

Note. As the prospective distance for this spark plug replacement is 100,000 km (62,000 mile). If the plug gap and insulation resistance are normal, check the plug state and clean it if necessary.

SPARK PLUG GAP CHECK

Check the plug gap with the wire type plug gauge. Replace it if the limit is exceeded.

Standard value: 0.7 - 0.8 mm (0.028 - 0.031 inch)

Limit: 0.95mm (0.037 inch)

Scheme 5

Scheme 6

1. Measure the insulation resistance. If the insulation resistance of the spark plug is under the limited value, clean the plug within 20 seconds using a plug cleaner.
2. After cleaning, measure the insulation resistance again. Replace the plug unless it is within the limited value. Limit: Minimum 10 Mohms
