P0014 Hyundai Code: Causes, Symptoms, and Solutions

If you own a Hyundai vehicle and have encountered the P0014 code, don’t worry! This code refers to an issue with the ‘B’ camshaft position timing, specifically an over-advanced condition or system performance problem in Bank 1. It commonly points to a problem with the camshaft position sensor (CMP) or related components. In this article, we will guide you through the causes, symptoms, diagnostic steps, and solutions for the P0014 code in Hyundai vehicles.

What is P0014 Code In Hyundai?

The P0014 code in Hyundai vehicles indicates a problem with the camshaft position timing in Bank 1. It can be caused by issues with the camshaft position sensor, engine oil, timing chain or belt, or the engine control module (ECM). Prompt diagnosis and repair are necessary to restore proper functioning.

Causes of P0014 Code in Your Hyundai?

1: Faulty Camshaft Position Sensor (CMP)

The CMP sensor is responsible for detecting the position of the camshaft. When the sensor malfunctions, it can send incorrect signals to the engine control module (ECM), leading to the P0014 code.

2: Engine Oil Contamination or Low Level

If the engine oil is contaminated or at a low level, it can affect the operation of the camshaft and its timing components. This can result in the camshaft position becoming over-advanced, triggering the P0014 code.

3: Malfunctioning Engine Oil Control Valve

The engine oil control valve regulates the flow of oil to the camshaft and its timing components. If the valve gets stuck or fails, it can disrupt the timing, leading to the P0014 code.

4: Timing Chain or Belt Issues

A stretched or damaged timing chain or belt can cause the camshaft timing to become over-advanced. This can happen due to regular wear and tear or improper maintenance.

5: Engine Control Module (ECM) Malfunction

The ECM controls various functions of the engine, including camshaft timing. If the ECM malfunctions or receives incorrect data from the camshaft position sensor, it may trigger the P0014 code.

Symptoms of P0014 Code

1: Check Engine Light (CEL) Illumination

One of the most noticeable symptoms is the illumination of the CEL on your dashboard. The ECM detects the camshaft timing issue and triggers the warning light.

2: Engine Misfires or Runs Rough

Due to incorrect camshaft timing, the engine may misfire or run roughly. You may experience a lack of power or unusual vibrations during acceleration.

3: Reduced Engine Performance

The over-advanced camshaft timing can lead to decreased engine performance. You may notice a decrease in power output and overall responsiveness.

4: Engine Hesitation or Stalling

A faulty camshaft timing can cause hesitation or even complete engine stalling, especially during idle or low-speed situations.

5: Irregular Engine Idling

Improper camshaft timing can disrupt the engine’s idle speed, resulting in a fluctuating or unstable idle.

Diagnostic and Troubleshooting Steps

Step 1: Inspect the Camshaft Position Sensor (CMP) and Wiring

• Locate the CMP sensor, which is typically found near the camshaft or cylinder head.
• Visually inspect the sensor and its wiring for any visible damage, loose connections, or corrosion.
• Use a multimeter to measure the sensor’s resistance. Compare the reading with the manufacturer’s specified range.
• If the resistance is outside the specified range, consider replacing the camshaft position sensor.

Step 2: Check the Engine Oil and Oil Control Valve

• Make sure the engine oil level is within the recommended range. If it’s low, top it up.
• Examine the oil for signs of contamination, such as metal particles or a milky appearance. If the oil is contaminated, it should be replaced.
• Locate the engine oil control valve and check for any blockages or malfunctions. Clean the valve if necessary, or replace it if cleaning doesn’t resolve the issue.

Step 3: Inspect the Timing Chain or Belt

• Refer to your vehicle’s service manual to find the location of the timing chain or belt.
• Inspect the chain or belt for signs of wear, stretching, or damage. Replace it if necessary.
• Ensure that the timing marks on the camshaft and crankshaft are aligned correctly.

Step 4: Verify the Engine Control Module (ECM) Functionality

• If the issue persists after performing the previous steps, it’s recommended to consult a professional mechanic or authorized Hyundai service center.
• The ECM may need diagnostic testing to determine if it is functioning correctly. In some cases, reprogramming or replacing the ECM may be necessary.

How to Fix P0014 Hyundai Code

Method 1: Replace the Camshaft Position Sensor

• Purchase a new camshaft position sensor that is compatible with your Hyundai model.
• Disconnect the battery to prevent any electrical damage.
• Locate the faulty sensor and carefully remove it.
• Install the new sensor and reconnect any wiring or connectors.
• Reconnect the battery and use an OBD-II scanner to clear the trouble codes.

Method 2: Clean or Replace the Engine Oil and Oil Control Valve

• Drain the existing engine oil and replace it with fresh, high-quality oil.
• Clean the engine oil control valve to remove any debris or sludge buildup. If cleaning doesn’t resolve the issue, consider replacing the valve.

Method 3: Repair or Replace the Timing Chain or Belt

• If you have experience with engine repairs, consult your vehicle’s service manual for the necessary steps to replace the timing chain or belt. If not, it’s best to seek professional assistance.

Method 4: Reprogram or Replace the Engine Control Module (ECM)

• If the ECM is found to be faulty, it may need reprogramming or replacement. It’s recommended to consult a qualified technician or Hyundai service centre for assistance.
