Component Inspection
■ OCV Coil Resistance Inspection
1.

Ignition switch "OFF"

2.

Disconnect battery (-) cable.

3.

Refer to "Shop Manual" and disconnect Exhaust OCV connector.

4.

Measure the resistance between Pin No. 2 (Power) terminal and Pin No. 1 (Control) terminal of Exhaust OCV component.

Specification : Approx. 6.9 - 7.9Ω at 20℃(68℉20℃)

5.

Is the measured value within specification?

▶ Go to "Exhaust OCV Actuation Test" procedure.

▶ Carefully re-do this troubleshooting guide steps.

▶ If problem still occurs, replace Exhaust OCV and then go to "Verification of Vehicle Repair" procedure.

■ Exhaust OCV Actuation Test
6.

Connect GDS to Data Link Connector(DLC).

7.

Ignition switch "ON" & Engine "ON"

8.

Perform "CVVT Exhaust" in "Actuation Test" with GDS.

9.

Monitor "EX-Cam Phaser 1 Duty Cycle" parameter in "Current Data" with GDS.

Specification : Refer to Figure below (Also, operating sound(Clicking sound) is heard)

10.

Is the parameter displayed within specification?

▶ Fault might be intermittent and caused either by poor contact in connectors or wiring harness, or it has been repaired and control module memory is not cleared yet. Thoroughly check terminal of battery, all connectors ( and connections) for looseness, bending, corrosion, contamination, deterioration, and/or damage.

▶ Repair or replace as necessary and then go to "Verification of Vehicle Repair" procedure.
