P1076 Hyundai Code - Camshaft Position Actuator Relay Circuit Low/Open
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 P1076 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 P1076 Hyundai?
- Faulty Electric Continuously Variable Valve Timing (eCVVT) Relay
- eCVVT Relay harness is open or shorted
- eCVVT Relay circuit poor electrical connection
