Code C1219 2017 GMC Sierra Description
The C1219 diagnostic trouble code (DTC) for the 2017 GMC Sierra indicates a problem with the brake pressure sensor supply voltage circuit, specifically that the voltage is lower than expected. The brake pressure sensor plays a critical role in the vehicle's braking system by measuring the hydraulic pressure within the brake lines. This information is vital for the vehicle's electronic stability control (ESC), anti-lock braking system (ABS), and traction control systems, as they rely on accurate pressure readings to function effectively.
Common Causes of C1219 2017 GMC Sierra
- Faulty Brake Pressure Sensor: The sensor itself may be malfunctioning or have internal failures.
- Wiring Issues: Damaged or corroded wiring in the brake pressure sensor circuit can lead to low voltage readings.
- Poor Electrical Connections: Loose or corroded connectors can disrupt the electrical flow to the sensor.
- Faulty ABS Module: The ABS control module may have internal faults affecting the sensor's voltage supply.
- Battery or Charging System Problems: Low voltage from the vehicle's battery or charging system can impact the sensor's performance.
Symptoms of C1219 2017 GMC Sierra
- Warning Lights: The ABS or brake warning light may illuminate on the dashboard.
- Erratic Braking Performance: The vehicle may experience inconsistent braking, with the ABS not engaging when needed.
- Increased Stopping Distance: Drivers may notice longer stopping distances, especially in emergency situations.
- Traction Control Malfunction: The traction control system may become inactive, leading to reduced vehicle stability.
- Brake Pedal Feel: The brake pedal may feel soft or spongy, indicating a potential issue with hydraulic pressure.
How to Fix C1219 2017 GMC Sierra
- Visual Inspection: Begin with a thorough visual inspection of the brake pressure sensor, wiring, and connectors for any signs of damage or corrosion.
- Testing Voltage Supply: Use a multimeter to check the voltage supply at the brake pressure sensor. Compare readings to manufacturer specifications.
- Replace Faulty Components: If the brake pressure sensor is found to be faulty, replace it with a new, OEM-quality part.
- Repair Wiring Issues: If damaged wiring or poor connections are identified, repair or replace the affected sections to ensure proper electrical flow.
- Clear Codes and Test Drive: After repairs, clear the DTCs using a scan tool and perform a test drive to confirm that the issue has been resolved and that the warning lights do not reappear.
Cost to Fix C1219 2017 GMC Sierra
The cost to repair the C1219 code can vary widely based on the specific issue identified. A rough estimate for parts and labor may range from $150 to $600. This includes the cost of a new brake pressure sensor (typically $50 to $200) and labor charges, which can range from $80 to $150 per hour. Diagnosis time may take 1 to 2 hours, depending on the complexity of the issue and the shop's efficiency. It's important to note that labor rates can differ significantly based on location, vehicle make and model, and engine type. In metropolitan areas or at dealerships, rates may be higher, while independent shops often offer more competitive pricing. For the most accurate estimate, it's advisable to check local rates and consult with a trusted mechanic.
