C1952 Code - Yaw Rate Sensor Circuit Open

Quick Answer

The C1952 diagnostic trouble code (DTC) indicates a problem with the yaw rate sensor circuit in a vehicle. Common causes include Damaged wiring: Physical damage to the wiring connecting the yaw rate sensor to the vehicle's computer can cause an open circuit, Corrosion: Corrosion or rust on the sensor connectors or wiring can disrupt the electrical connection, Faulty sensor: A malfunctioning or failed yaw rate sensor can also trigger this code. 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 C1952 Description

The C1952 diagnostic trouble code (DTC) indicates a problem with the yaw rate sensor circuit in a vehicle. The yaw rate sensor is a crucial component of the vehicle's stability control system, as it measures the rate of rotation around the vehicle's vertical axis. This information is used by the vehicle's electronic stability control (ESC) system to help maintain stability during sudden maneuvers, such as swerving or cornering.

Common Causes of C1952

  1. Damaged wiring: Physical damage to the wiring connecting the yaw rate sensor to the vehicle's computer can cause an open circuit.
  2. Corrosion: Corrosion or rust on the sensor connectors or wiring can disrupt the electrical connection.
  3. Faulty sensor: A malfunctioning or failed yaw rate sensor can also trigger this code.
  4. Loose connections: Loose or poor connections between the sensor and the vehicle's computer can result in an open circuit.
  5. Electronic control unit (ECU) issues: Problems with the ECU that processes the sensor data can also lead to this code.

Symptoms of C1952

  1. Loss of traction control: The vehicle may experience difficulty maintaining traction during acceleration or cornering.
  2. Stability control warning light: The ESC warning light may illuminate on the dashboard to indicate a problem with the system.
  3. Unusual handling: The vehicle may feel less stable or exhibit erratic handling characteristics.
  4. ABS system malfunction: In some cases, the anti-lock braking system (ABS) may also be affected, leading to issues with braking performance.
  5. Vehicle veering to one side: The vehicle may pull to one side during sudden maneuvers or on uneven road surfaces.

How to Fix C1952

  1. Diagnose the issue: Use a diagnostic scan tool to retrieve the specific fault code and pinpoint the exact cause of the yaw rate sensor circuit open.
  2. Inspect wiring and connections: Check the wiring harness, connectors, and terminals for any signs of damage, corrosion, or loose connections. Repair or replace as needed.
  3. Test the sensor: Test the yaw rate sensor itself to determine if it is functioning properly. Replace the sensor if it is faulty.
  4. Clear the DTC: Once the repairs are completed, clear the DTC from the vehicle's computer system to reset the stability control system.
  5. Test drive: Take the vehicle for a test drive to ensure that the ESC system is functioning correctly and that the symptoms associated with the code have been resolved.

Cost to Fix C1952

The cost of repairing a yaw rate sensor circuit open issue can vary depending on the specific cause of the problem and the vehicle's make and model. In general, the cost of parts for a new yaw rate sensor can range from $100 to $300, while labor costs can add an additional $100 to $200. Overall, the total repair cost for this issue typically falls within the range of $200 to $500. However, it's important to note that labor rates at auto repair shops can vary widely, so it's recommended to obtain quotes from multiple shops to get a more accurate estimate for your specific situation.
