Code C1252 Description
The C1252 diagnostic trouble code (DTC) refers to a Longitudinal Acceleration Sensor Circuit Low Voltage issue. This code indicates that the vehicle's onboard computer has detected a problem with the longitudinal acceleration sensor circuit, specifically registering a lower voltage than expected. The longitudinal acceleration sensor is a crucial component of the vehicle's stability control system, also known as the electronic stability control (ESC) system. This sensor measures the vehicle's acceleration in the direction of travel, helping the ESC system to detect any loss of traction or stability.
Common Causes of C1252
- Damaged wiring or connectors in the longitudinal acceleration sensor circuit.
- Faulty longitudinal acceleration sensor.
- Malfunctioning ESC module.
- Corrosion or contamination in the sensor connections.
- Electrical issues such as a blown fuse related to the sensor circuit.
Symptoms of C1252
- Illuminated ESC or traction control warning light on the dashboard.
- Loss of traction control and stability assistance.
- Increased difficulty in maintaining control during cornering or sudden maneuvers.
- Strange noises coming from the ESC system or sensor area.
- Inconsistent or jerky acceleration patterns.
How to Fix C1252
- Connect a diagnostic scanner to the vehicle's OBD-II port to retrieve the specific trouble codes and confirm the issue.
- Inspect the wiring and connectors in the longitudinal acceleration sensor circuit for any damage, corrosion, or loose connections.
- Test the longitudinal acceleration sensor using a multimeter to determine if it is functioning correctly.
- If the sensor is faulty, replace it with a new OEM or high-quality aftermarket sensor.
- Clear the DTCs from the vehicle's computer and perform a test drive to verify that the issue has been resolved.
Cost to Fix C1252
The typical repair costs for addressing a Longitudinal Acceleration Sensor Circuit Low Voltage issue can range from $200 to $500, including parts and labor. However, the specific diagnosis time and labor rates at auto repair shops can vary based on factors such as location, vehicle make and model, and engine type. It is advisable to check with local repair shops for a more accurate estimate based on your specific circumstances. Keep in mind that rates in metropolitan areas or at dealerships may be higher, while independent shops often offer more competitive pricing.
