P208B Ford Code - Reductant Pump 'A' Control Range/Performance
Quick Answer
The P208B diagnostic trouble code (DTC) for Ford vehicles indicates a problem with the reductant pump 'A' control range/performance. Common causes include Faulty Reductant Pump: The reductant pump itself may be malfunctioning, leading to issues with its control range and performance, Wiring or Connector Issues: Damaged or corroded wiring/connectors can disrupt communication between the reductant pump and the PCM, Defective SCR System Components: Other components of the SCR system, such as sensors or modules, may be faulty, affecting the reductant pump's operation. 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 P208B Ford Description
The P208B diagnostic trouble code (DTC) for Ford vehicles indicates a problem with the reductant pump 'A' control range/performance. The reductant pump is a crucial component of the selective catalytic reduction (SCR) system, which helps reduce harmful emissions by injecting a urea-based solution (DEF - diesel exhaust fluid) into the exhaust stream. This process converts nitrogen oxides (NOx) into harmless nitrogen and water vapor.
Common Causes of P208B Ford
- Faulty Reductant Pump: The reductant pump itself may be malfunctioning, leading to issues with its control range and performance.
- Wiring or Connector Issues: Damaged or corroded wiring/connectors can disrupt communication between the reductant pump and the PCM.
- Defective SCR System Components: Other components of the SCR system, such as sensors or modules, may be faulty, affecting the reductant pump's operation.
- Software/PCM Malfunction: A software glitch or PCM issue can also trigger the P208B code by incorrectly interpreting data from the reductant pump.
Symptoms of P208B Ford
- Illuminated Check Engine Light: The most common symptom associated with the P208B code is the illumination of the Check Engine Light on the vehicle's dashboard.
- Reduced Engine Performance: The vehicle may experience a decrease in engine power or acceleration due to the inefficient operation of the SCR system.
- Poor Fuel Economy: A faulty reductant pump can impact fuel efficiency, causing the vehicle to consume more fuel than usual.
- Failed Emissions Test: If the SCR system is not functioning properly, the vehicle may fail emissions testing due to increased NOx emissions.
How to Fix P208B Ford
- Diagnose the Issue: Use a scan tool to retrieve the DTC and perform a thorough inspection of the reductant pump, wiring, and related components.
- Test the Reductant Pump: Check the reductant pump's operation using a multimeter or oscilloscope to verify if it is functioning within the specified range.
- Inspect Wiring and Connectors: Look for any damaged or corroded wiring/connectors and repair or replace them as necessary.
- Replace Faulty Components: If the reductant pump or any other SCR system component is found to be defective, replace it with a new part.
- Clear DTC and Test Drive: Clear the DTC from the PCM's memory after completing the repairs and test drive the vehicle to ensure the issue has been resolved.
Cost to Fix P208B Ford
The typical repair costs for addressing a P208B code on a Ford vehicle can range from $200 to $500, depending on the extent of the issue and the cost of replacement parts. This estimate includes the cost of the reductant pump, wiring/connectors, and labor charges. It's important to note that diagnosis time and labor rates can vary depending on the location of the auto repair shop, the vehicle's make and model, and the type of engine.
