INSPECTION

1. INSPECT MASS AIR FLOW METER

a. Check the output voltage.

  1. Apply battery voltage across terminals 1 (+B) and 2 (E2G).

  2. Using a voltmeter, connect the positive (+) tester probe to terminal VG, and negative (−) tester probe to terminal E2G.

  3. Blow air into the MAF meter, and check that the voltage fluctuates.

b. Measure the resistance between terminals 4 (THA) and 5 (E2).

Standard

:

If the result is not as specified, replace the MAF meter.

If the result is not as specified, replace the MAF meter.

2. INSPECT CAMSHAFT TIMING OIL CONTROL VALVE ASSY

a. Measure the resistance between the terminals.

Standard: 6.9 to 7.9 W at 20 C (68 F)

If the result is not as specified, replace the OCV assy.

b. Connect the battery’s positive (+) lead to terminal 1 and

b. Connect the battery’s positive (+) lead to terminal 1 and negative (−) lead to terminal 2, and check the movement of the valve.

NOTICE: Confirm that the valve moves freely and does not become stuck in any position.

If necessary, replace the OCV assy.

HINT: If the valve cannot return properly because of foreign matter, a small pressure leak in the advanced direction may occur and a DTC will be output.

3. INSPECT ACCELERATOR PEDAL ASSY

3. INSPECT ACCELERATOR PEDAL ASSY

a. Measure the resistance between the terminals.

Standard

:

If the result is not as specified, replace the pedal assy.

If the result is not as specified, replace the pedal assy.

4. INSPECT THROTTLE BODY ASSY

4. INSPECT THROTTLE BODY ASSY

a. Measure the resistance between the terminals.

Standard

:

If the result is not as specified, replace the throttle body

If the result is not as specified, replace the throttle body assy.

5. INSPECT ENGINE COOLANT TEMPERATURE

5. INSPECT ENGINE COOLANT TEMPERATURE

a. Measure the resistance between terminals 1 and 2.

Standard

:

If the result is not as specified, replace the .

If the result is not as specified, replace the .

NOTICE: If checking the engine coolant temperature in the water, keep the terminals dry. After the check, wipe the dry.

6. INSPECT KNOCK

6. INSPECT KNOCK

a. Using an ohmmeter, measure the resistance between the terminals.

Standard: 120 to 280 kW at 20 C (68 F)

HINT: If the result is not as specified, replace the .

7. INSPECT RELAY (Marking: EFI, C/OPN)

7. INSPECT RELAY (Marking: EFI, C/OPN)

a. Using an ohmmeter, measure the resistance of the relay.

Standard

:

If the result is not as specified, replace the relay.

If the result is not as specified, replace the relay.
