Code C1250 GMC Description
The C1250 GMC code indicates a problem with the lateral acceleration sensor circuit, specifically that the voltage is too high. The lateral 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 lateral acceleration, which is the force acting on the vehicle from side to side during cornering or swerving. The ESC system uses this information to help maintain stability and prevent skidding or loss of control.
Common Causes of C1250 GMC
- Faulty lateral acceleration sensor.
- Damaged wiring or connectors in the sensor circuit.
- Corrosion or contamination affecting the sensor or circuit.
- Electrical issues such as a short circuit or open circuit in the circuit.
- Issues with the ESC module or related components.
Symptoms of C1250 GMC
- Illumination of the ESC or traction control warning light on the dashboard.
- Increased difficulty in maintaining control of the vehicle during cornering.
- Unusual noises or sensations coming from the ESC system during driving.
- Reduced responsiveness or effectiveness of the ESC system in preventing skidding.
How to Fix C1250 GMC
- Begin by conducting a thorough inspection of the lateral acceleration sensor and its circuitry to identify any visible damage or issues.
- Test the sensor's voltage output using a multimeter to determine if it is within the specified range.
- Check the wiring and connectors for any signs of damage, corrosion, or loose connections. Repair or replace as necessary.
- Clear the diagnostic trouble codes from the vehicle's system using a scan tool and test drive the vehicle to ensure the issue has been resolved.
- If the problem persists, consider replacing the lateral acceleration sensor or consulting a professional technician for further diagnosis and repair.
Cost to Fix C1250 GMC
The cost of repairing a lateral acceleration sensor circuit high voltage issue can vary depending on the specific cause of the problem and the vehicle's make and model. In general, the cost of replacing a faulty lateral acceleration sensor can range from $150 to $300, including parts and labor. Additional costs may apply if wiring or connectors need to be repaired or replaced. It is advisable to consult with a trusted auto repair shop to obtain a more accurate estimate based on the individual circumstances of the vehicle. Keep in mind that diagnostic time and labor rates can vary, so it's recommended to inquire about these factors when seeking a repair quote.
