Code P1305 Hyundai Description
The P1305 Hyundai code indicates a fault with the phase sensor in the vehicle. The phase sensor is responsible for detecting the position of the camshaft in relation to the crankshaft, allowing the Engine Control Module (ECM) to accurately adjust the fuel injection timing and ignition timing. When the phase sensor is abnormal, it can lead to misfires, poor engine performance, and potentially even engine stalling.
Common Causes of P1305 Hyundai
- Faulty phase sensor
- Wiring issues or poor connections
- ECM software malfunction
- Camshaft or crankshaft position sensor failure
- Timing belt or chain issues
Symptoms of P1305 Hyundai
- Engine misfires
- Rough idling
- Hesitation during acceleration
- Decreased fuel efficiency
- Engine stalling
How to Fix P1305 Hyundai
- Diagnose the issue by using a scan tool to read the fault codes and check the phase sensor's operation.
- Inspect the wiring and connections related to the phase sensor for any damage or corrosion. Repair or replace as necessary.
- Test the phase sensor's resistance and signal output to determine if it is functioning correctly. Replace the sensor if it fails the tests.
- Check the camshaft and crankshaft position sensors for proper operation and replace if necessary.
- Clear the fault codes and perform a test drive to confirm that the issue has been resolved.
Cost to Fix P1305 Hyundai
The typical repair costs for a phase sensor abnormality can range from $150 to $400, including parts and labor. However, actual costs may vary depending on the location, vehicle make and model, and the specific diagnostic time and labor rates of the auto repair shop.

Frequently Asked Questions about P1305 Hyundai Code
1. What does the OBDII code P1305 mean on a Hyundai?
P1305 on a Hyundai indicates a "Phase Sensor Abnormal" issue, which typically means the camshaft position sensor is malfunctioning or sending improper signals to the engine control module (ECM).
2. What are the common symptoms of the P1305 code in a Hyundai?
Symptoms may include rough idling, engine misfiring, poor acceleration, reduced fuel efficiency, difficulty starting the engine, or the check engine light illuminating.
3. What causes the P1305 code to appear on a Hyundai?
Common causes include a faulty camshaft position sensor, damaged wiring or connectors, a malfunctioning ECM, or mechanical issues such as a misaligned timing belt or chain.
4. Can I drive my Hyundai with the P1305 code active?
It is not recommended to drive with the P1305 code active, as it can lead to further engine damage, poor performance, and increased fuel consumption.
5. How do I diagnose the P1305 code on my Hyundai?
Start by inspecting the camshaft position sensor, its wiring, and connectors for damage or corrosion. Use an OBDII scanner to confirm the code and perform additional tests, such as checking the timing belt or chain alignment.
6. How do I fix the P1305 code on a Hyundai?
Repairs may involve replacing the camshaft position sensor, repairing or replacing damaged wiring, ensuring proper timing alignment, or, in rare cases, replacing the ECM.
7. How much does it cost to fix the P1305 code on a Hyundai?
The cost depends on the specific repair. Replacing a camshaft position sensor typically ranges from $100 to $300, while more complex issues like timing adjustments or ECM replacement can be more expensive.
8. Can a dirty or damaged camshaft cause the P1305 code?
Yes, a dirty or damaged camshaft can interfere with the phase sensor's readings and trigger the P1305 code.
9. Will clearing the P1305 code with a scanner fix the problem?
Clearing the code will temporarily turn off the check engine light, but it won't fix the underlying issue. The code will likely return unless the problem is properly addressed.
10. Can a faulty crankshaft position sensor trigger the P1305 code on a Hyundai?
While P1305 specifically relates to the camshaft position sensor, a faulty crankshaft position sensor or issues with synchronization between the two sensors can contribute to similar problems.
