Code C1252 GMC Description
The C1252 GMC code indicates a problem with the longitudinal acceleration sensor circuit, specifically low voltage. This sensor is responsible for measuring the vehicle's forward and backward acceleration, providing crucial data to the vehicle's stability control system. When the sensor detects low voltage, it means that there is a malfunction in the circuit that could lead to inaccurate readings or a complete failure of the sensor.
Common Causes of C1252 GMC
- Damaged wiring or connectors in the longitudinal acceleration sensor circuit.
- Failed longitudinal acceleration sensor.
- Corrosion or contamination in the sensor connector.
- Issues with the electronic control module (ECM) or related components.
- Physical damage to the sensor due to external factors.
Symptoms of C1252 GMC
- Illuminated ABS or stability control warning light on the dashboard.
- Loss of traction control or stability control functionality.
- Erratic or unpredictable braking behavior.
- Inaccurate speedometer readings.
- Harsh or delayed shifting in automatic transmissions.
How to Fix C1252 GMC
- Begin by performing a thorough inspection of the wiring and connectors in the longitudinal acceleration sensor circuit. Look for any signs of damage, corrosion, or loose connections.
- Test the longitudinal acceleration sensor using a multimeter to check for proper voltage output. Replace the sensor if it is found to be faulty.
- Clean the sensor connector and ensure a secure connection to eliminate any potential issues caused by corrosion or contamination.
- If the issue persists, diagnose the electronic control module (ECM) and related components to determine if there is a fault in the control system.
- Clear the diagnostic trouble codes from the vehicle's system using an OBD-II scanner and perform a road test to ensure that the issue has been resolved.
Cost to Fix C1252 GMC
The typical repair costs for addressing a C1252 GMC code can vary depending on the specific cause of the issue. Generally, the cost of replacing a longitudinal acceleration sensor can range from $100 to $300, while addressing wiring or connector problems may cost between $50 and $150. If the issue is related to the electronic control module (ECM), the repair costs could be higher, potentially reaching $500 or more.
