Code P1774 Hyundai Description
The P1774 code for Hyundai vehicles specifically refers to an issue with the CRC sensor. The CRC sensor, also known as the Clutch Regulator Control Sensor, plays a crucial role in the vehicle's transmission system. This sensor is responsible for monitoring the hydraulic pressure within the clutch regulator control system. When the sensor detects abnormal hydraulic pressure levels, it sends a signal to the vehicle's engine control module (ECM) to trigger the P1774 fault code.
