U0467 Mercury Code - Invalid Data Received From Fuel Additive Control Module
Quick Answer
The U0467 diagnostic trouble code (DTC) for Mercury vehicles indicates that the Engine Control Module (ECM) has detected invalid data being received from the Fuel Additive Control Module. Common causes include Faulty Fuel Additive Control Module: The module itself may be malfunctioning, sending incorrect data to the ECM, Wiring Issues: Damaged or corroded wiring connections between the Fuel Additive Control Module and the ECM can disrupt data transmission, Connector Problems: Loose or damaged connectors can also lead to communication errors between the modules. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

Code U0467 Mercury Description
The U0467 diagnostic trouble code (DTC) for Mercury vehicles indicates that the Engine Control Module (ECM) has detected invalid data being received from the Fuel Additive Control Module. The Fuel Additive Control Module is responsible for managing the fuel additives in the vehicle, such as those used for emissions control or performance enhancement. When the ECM detects that the data being received from this module is incorrect or inconsistent, it triggers the U0467 code.
Common Causes of U0467 Mercury
- Faulty Fuel Additive Control Module: The module itself may be malfunctioning, sending incorrect data to the ECM.
- Wiring Issues: Damaged or corroded wiring connections between the Fuel Additive Control Module and the ECM can disrupt data transmission.
- Connector Problems: Loose or damaged connectors can also lead to communication errors between the modules.
- Software Glitch: An internal software glitch within the Fuel Additive Control Module may cause it to send invalid data to the ECM.
Symptoms of U0467 Mercury
- Check Engine Light: The most common symptom associated with the U0467 code is the illumination of the Check Engine Light on the vehicle's dashboard.
- Reduced Fuel Efficiency: Drivers may notice a decrease in fuel efficiency, as the incorrect data from the Fuel Additive Control Module can impact the engine's performance.
- Engine Misfires: The engine may experience misfires or rough idling due to the disrupted fuel mixture caused by the invalid data.
- Emissions Issues: The vehicle may fail emissions tests or produce higher emissions than usual due to the malfunctioning Fuel Additive Control Module.
How to Fix U0467 Mercury
- Diagnose the Issue: Use a diagnostic scanner to retrieve the trouble codes and perform a thorough inspection of the Fuel Additive Control Module, wiring, and connectors.
- Repair or Replace Module: Depending on the diagnosis, repair or replace the faulty Fuel Additive Control Module to ensure accurate data transmission.
- Check Wiring and Connectors: Inspect the wiring harness and connectors for any damage or corrosion, repairing or replacing as needed.
- Clear Codes: After completing the repairs, clear the DTCs from the ECM memory and test drive the vehicle to ensure the issue has been resolved.
- Perform Emissions Test: If emissions were affected by the U0467 code, perform an emissions test to verify that the vehicle is now in compliance.
Cost to Fix U0467 Mercury
The typical repair costs for addressing the U0467 code on a Mercury vehicle can vary depending on the specific cause of the issue and the extent of the repairs needed. In general, the cost of replacing a Fuel Additive Control Module can range from $200 to $500, including parts and labor. Additional costs may be incurred for diagnosing the problem, repairing wiring or connectors, and performing emissions tests.
