Code C0249 Pontiac Description
The C0249 diagnostic trouble code (DTC) for Pontiac vehicles indicates a "Left Normal Force Error." This code is related to the Electronic Brake Control Module (EBCM) and specifically refers to an issue with the left normal force sensor. The normal force sensor is responsible for measuring the force applied to the wheel during braking, allowing the EBCM to adjust brake pressure accordingly for optimal performance.
Common Causes of C0249 Pontiac
- Faulty left normal force sensor
- Wiring or connection issues in the left normal force sensor circuit
- Corrosion or damage to the sensor or its mounting location
- EBCM software or calibration issues
- Mechanical damage to the brake system affecting sensor readings
Symptoms of C0249 Pontiac
- Illuminated ABS warning light on the dashboard
- Traction control system malfunction
- Uneven braking or pulling to one side during braking
- Increased stopping distances
- Decreased overall braking performance
How to Fix C0249 Pontiac
- Begin by conducting a thorough visual inspection of the left normal force sensor and its wiring harness for any signs of damage or corrosion.
- Use a diagnostic scan tool to retrieve the specific error codes and data related to the left normal force sensor.
- Test the sensor's output using a multimeter to verify its functionality and compare readings to specifications.
- If the sensor is faulty, replace it with a new OEM or high-quality aftermarket sensor.
- Clear the DTCs from the EBCM memory and perform a road test to ensure proper sensor operation and brake system functionality.
Cost to Fix C0249 Pontiac
The cost of repairing a C0249 code on a Pontiac can vary depending on the specific model and year of the vehicle, as well as the extent of the issue. In general, the cost of parts for a left normal force sensor replacement can range from $100 to $300, while labor costs can add another $100 to $200. Overall, the total repair cost for addressing a C0249 code typically falls within the range of $200 to $500.

Frequently Asked Questions about C0249 Pontiac Code
1. What does the OBDII code C0249 mean on a Pontiac?
The C0249 code indicates a "Left Normal Force Error," which is related to the Electronic Brake Control Module (EBCM) detecting an issue with the left front wheel's normal force sensor or related system.
2. What are the common symptoms of the C0249 code?
Symptoms may include the ABS warning light illuminating, reduced or erratic braking performance, or the vehicle pulling to one side during braking.
3. What causes the C0249 code on a Pontiac?
Common causes include a faulty normal force sensor, damaged wiring or connectors in the ABS system, or a malfunctioning EBCM.
4. How do I diagnose the C0249 code on my Pontiac?
Diagnosis involves using a scan tool to confirm the code, visually inspecting the wiring and connectors near the left front wheel, and testing the normal force sensor for proper operation.
5. Can I drive my Pontiac with the C0249 code?
While the vehicle may still be drivable, it is not recommended, as the ABS system may not function correctly, compromising braking safety.
6. How do I fix the C0249 code on a Pontiac?
Repairs may include replacing the left normal force sensor, repairing damaged wiring, cleaning corroded connectors, or reprogramming or replacing the EBCM if necessary.
7. What tools are needed to fix the C0249 code?
You will need an OBDII scanner, a multimeter for electrical testing, and possibly basic hand tools for sensor or wiring repairs.
8. How much does it cost to repair the C0249 code?
Repair costs can vary, ranging from $50 to $200 for a sensor replacement, and higher if the EBCM needs to be replaced.
9. Can a faulty wheel speed sensor cause the C0249 code?
No, the C0249 code specifically relates to the left normal force sensor, not the wheel speed sensor.
10. Will clearing the C0249 code with a scan tool fix the problem?
No, clearing the code will only temporarily remove it. The underlying issue must be repaired to prevent the code from returning.
