P1075 Hyundai Code - Camshaft Position Actuator Relay Circuit Range/Performance
Quick Answer
The CVVT (Continuously Variable Valve Timing) system is installed on the chain sprocket of the camshafts. Common causes include Faulty Electric Continuously Variable Valve Timing (eCVVT) Relay, eCVVT Relay harness is open or shorted, eCVVT Relay circuit poor electrical connection. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

Code P1075 Hyundai Description
Electric Continuously Variable Valve Timing (eCVVT) which consists of a DC motor, warm gear, and position sensor is installed at the intake camshaft to control the valve timing of intake.
The CVVT controller at the exhaust camshaft regulates the camshaft angle using oil pressure through the OCV.
The PCM controls eCVVT at intake and CVVT at exhaust to obtain optimized valve timing according to the signals output from airflow, throttle position, and engine coolant temperature.
As result, the relative position between the camshaft and the crankshaft becomes optimal and the engine torque improves, fuel economy improves, and exhaust emissions decrease under overall driving conditions. Also, the PCM can control valve timing at cold start and at a time of start with eCVVT.
What are the Possible Causes of the DTC P1075 Hyundai?
- Faulty Electric Continuously Variable Valve Timing (eCVVT) Relay
- eCVVT Relay harness is open or shorted
- eCVVT Relay circuit poor electrical connection

The P1075 code indicates a problem with the Camshaft Position Actuator Relay Circuit, specifically a range or performance issue.
2. What are the common symptoms of a P1075 code in a Hyundai?
Symptoms may include rough idling, poor acceleration, reduced fuel efficiency, engine misfires, or the Check Engine Light turning on.
3. What causes the P1075 code to appear in a Hyundai?
Common causes include a faulty camshaft position actuator relay, wiring issues, a malfunctioning camshaft position sensor, or a problem with the engine control module (ECM).
4. Can I drive my Hyundai with a P1075 code?
While the car may still be drivable, ignoring the issue could lead to engine damage, reduced performance, and potential safety concerns. It’s best to address it promptly.
5. How do I diagnose the P1075 code on a Hyundai?
Diagnosis typically involves using an OBDII scanner to confirm the code, inspecting the actuator relay and wiring for damage, and testing the camshaft position sensor with a multimeter.
6. How is the P1075 code fixed on a Hyundai?
Repairs may involve replacing the faulty camshaft position actuator relay, repairing damaged wiring, replacing the camshaft position sensor, or reprogramming/updating the ECM.
7. How much does it cost to fix the P1075 code in a Hyundai?
Repair costs can vary but typically range from $100 to $300, depending on whether parts like the actuator relay or sensor need replacement.
8. Can a dirty engine oil cause the P1075 code?
Yes, insufficient or dirty engine oil can affect the camshaft position actuator’s performance, potentially triggering the P1075 code.
9. What tools are needed to troubleshoot a P1075 code?
An OBDII scanner, a multimeter, and basic tools for inspecting and replacing wiring or sensors are typically needed.
10. Will clearing the P1075 code fix the problem permanently?
Clearing the code may turn off the Check Engine Light temporarily, but it won’t resolve the underlying issue. Proper diagnosis and repair are necessary to avoid recurrence.
