Question 1

What is the OCV coil resistance specification for the 2017 Hyundai Elantra?

Accepted Answer

The normal OCV (Oil Control Valve) coil resistance specification is approximately 9.9 ± 0.5 Ω at 20°C (68°F). If the measured resistance is not within this specification, the OCV should be substituted with a known-good unit and checked for proper operation. (Page 6)

Question 2

What should I check first during the system inspection for DTC P0014-00?

Accepted Answer

During the system inspection, first check that the oil level is acceptable and inspect for any oil leakage around the OCV. If a problem is found, repair or replace as necessary and proceed to the Verification of Vehicle Repair procedure. (Page 9)

Question 3

What does it mean if the DTC status shows 'History (Not Present)' vs. 'Present'?

Accepted Answer

A 'History (Not Present)' fault means the DTC occurred previously but has since been cleared and is not currently active. A 'Present' fault means the DTC is occurring at the current time and the issue is active. If the fault is intermittent and not present, it may be caused by the PCM memory not having been cleared. (Page 7)

Question 4

What are the possible causes of DTC P0014-00 on my Hyundai?

Accepted Answer

The possible causes of DTC P0014-00 include an oil leak, a faulty Oil Control Valve (OCV), and a faulty CVVT Assembly. These causes are associated with Case 1, which involves a slow response of the actuator. (Page 2)

Question 5

What does DTC P0014-00 mean on my 2017 Hyundai Elantra?

Accepted Answer

DTC P0014-00 refers to 'B' Camshaft Position – Timing Over-Advanced Or System Performance (Bank 1). The PCM accumulates the deviation of the camshaft position from its target point during stable driving conditions and sets this DTC when the accumulated deviation is too high. The target camshaft position is a predetermined value depending on engine speed and throttle angle. (Page 2)

Question 6

How do I check if the Oil Control Valve (OCV) is working properly?

Accepted Answer

Start the engine and let it idle, then with the OCV connector disconnected, connect 12V and a ground to terminals 2 and 1 of the OCV on the component side. Under normal conditions, this should cause a rough idle or engine stall. You can also apply battery voltage and listen for a clicking sound, repeating the procedure 4 or 5 times to ensure OCV reliability. (Page 10)

Question 7

How do I check the CVVT assembly for proper operation?

Accepted Answer

Remove the CVVT assembly and check that it is locked, then apply low air pressure of approximately 150 kPa (1.5 kg/cm², 21 psi) to the exposed camshaft port to release the lock pin. Turn the CVVT to the advance direction and allow it to move in both advance and delay directions to ensure there is no binding and that it moves freely in a range of about 20°. Finally, turn the CVVT by hand to confirm it locks at the maximum delay angle position. (Page 11-12)

Question 8

What is the correct resistance specification for the Oil Control Valve (OCV)?

Accepted Answer

The normal resistance specification for the Oil Control Valve (OCV) is approximately 9.9 ± 0.5 Ω at 20°C (68°F). To check this, turn the ignition OFF, disconnect the OCV connector, and measure resistance between the power and signal terminals on the component side. (Page 9)

Question 9

What should I do to verify the repair after fixing DTC P0014-00?

Accepted Answer

Connect the GDS and select the 'DTC' button, then press 'DTC Status' and confirm that the 'DTC Readiness Flag' indicates 'Completed.' Read the DTC Status parameter and check if it displays 'History (Not Present),' which means the system is performing to specification and you can clear the DTC. (Page 13)

Question 10

What is the difference between a 'History' fault and a 'Present' fault for DTC P0014-00?

Accepted Answer

A 'History (Not Present)' fault means the DTC occurred previously but has since been cleared. A 'Present' fault means the DTC is actively occurring at the current time. This distinction is important when diagnosing whether the issue is intermittent or ongoing. (Page 7)

Question 15

How do I test the OCV operation manually?

Accepted Answer

Start the engine and let it idle with the OCV connector still disconnected. Connect 12V and ground to terminals 2 and 1 of the OCV on the component side. The normal value should show normal engine speed, while an abnormal condition would show rough idle or engine stall. Repeat this procedure 4-5 times to ensure OCV reliability.

Question 16

What should I check during the visual inspection for this DTC?

Accepted Answer

Check that the oil level is adequate, and inspect for oil leakage around the Oil Control Valve. If any leakage is found, repair or replace the components as necessary. This visual inspection is a critical part of the system inspection procedure.

Question 17

How do I inspect the CVVT assembly for problems?

Accepted Answer

Remove the CVVT assembly and check that it is locked. Apply masking tape to oil path holes except the advance hole indicated by the arrow. Apply low air pressure of approximately 150 kPa (1.5 kg/cm², 21 psi) to the exposed camshaft port while turning the CVVT in the advance direction. Verify it moves freely in both advance and delay directions within a range of about 20° and locks properly in the maximum delay angle position.

Question 18

What indicates a poor connector connection during diagnostics?

Accepted Answer

Disconnect the OCV and PCM connectors and inspect for looseness, poor connection, bending, corrosion, contamination, deterioration, or damage. When monitoring camshaft actual position in Current Data, wiggle the harness, connector, and terminals while watching the values.
