Code C1305 Mercury Description
The C1305 diagnostic trouble code for Mercury vehicles indicates a Longitudinal Accelerometer Signal Fault. This fault occurs when the vehicle's onboard computer system detects an issue with the longitudinal accelerometer signal. The longitudinal accelerometer is responsible for measuring the vehicle's acceleration in the forward or backward direction. This data is crucial for various vehicle systems, including traction control, stability control, and anti-lock braking systems.
Common Causes of C1305 Mercury
- Damaged wiring or connectors leading to the longitudinal accelerometer.
- Faulty longitudinal accelerometer sensor.
- Issues with the vehicle's onboard computer system.
- Water or moisture intrusion affecting the accelerometer components.
- Physical damage to the accelerometer due to impact or debris.
Symptoms of C1305 Mercury
- Illuminated ABS or traction control warning light on the dashboard.
- Loss of traction or stability during acceleration or deceleration.
- Increased stopping distance or reduced braking effectiveness.
- Unusual noises or vibrations while driving, especially during braking or cornering.
How to Fix C1305 Mercury
- Begin by conducting a thorough diagnostic scan to retrieve the specific fault codes and pinpoint the issue with the longitudinal accelerometer signal.
- Inspect the wiring and connectors leading to the accelerometer for any signs of damage or corrosion. Repair or replace as necessary.
- Test the longitudinal accelerometer sensor to determine if it is functioning correctly. Replace if faulty.
- Check the vehicle's onboard computer system for any software issues or malfunctions that may be affecting the accelerometer signal.
- Clear the fault codes from the system and perform a test drive to ensure the issue has been resolved.
Cost to Fix C1305 Mercury
The typical repair costs for addressing a Longitudinal Accelerometer Signal Fault on a Mercury vehicle can range from $200 to $500, including parts and labor. However, it is important to note that 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. Most auto repair shops charge between $80 and $150 per hour for labor, but rates may be higher in metropolitan areas or at dealerships, while independent shops often charge less. It is recommended to obtain local estimates for a more accurate cost assessment.

Frequently Asked Questions about C1305 Mercury Code
1. What does the OBDII code C1305 mean for a Mercury vehicle?
C1305 indicates a fault with the longitudinal accelerometer signal, which is part of the ABS or traction control system.
2. What are the common symptoms of the C1305 code in a Mercury?
Symptoms may include the ABS or traction control warning light being illuminated, reduced braking performance, or issues with stability control.
3. What causes the C1305 code to be triggered?
Common causes include a faulty longitudinal accelerometer, damaged wiring or connectors, or a malfunctioning ABS control module.
4. Can I still drive my Mercury with the C1305 code active?
While the vehicle may still be drivable, safety features like ABS and traction control may be compromised, so caution is advised.
5. How do I diagnose the C1305 code on a Mercury?
Diagnosis involves using a scan tool to confirm the code, inspecting the accelerometer and its wiring, and testing the ABS control module if necessary.
6. Where is the longitudinal accelerometer located in a Mercury vehicle?
The longitudinal accelerometer is typically located near the center of the vehicle, often under the center console or near the floor.
7. How can I fix the C1305 code on my Mercury?
Repairs may include replacing the faulty accelerometer, repairing damaged wiring or connectors, or reprogramming/replacing the ABS control module.
8. How much does it cost to repair the C1305 code on a Mercury?
Costs vary depending on the issue, but replacing a longitudinal accelerometer typically costs $150–$300, excluding labor.
9. Can a weak battery cause the C1305 code to appear?
Yes, a weak or failing battery can sometimes cause electrical faults, including issues with the accelerometer signal.
10. Will clearing the C1305 code fix the problem permanently?
Clearing the code will turn off warning lights temporarily, but the underlying issue must be addressed to prevent the code from returning.
