Code P208B Description
The P208B diagnostic trouble code (DTC) refers to an issue with the Reductant Pump Control Range/Performance in the vehicle's emissions system. The reductant pump is responsible for supplying the diesel exhaust fluid (DEF) to the Selective Catalytic Reduction (SCR) system, which helps reduce harmful emissions. When this code is triggered, it usually indicates a problem with the reductant pump's control range or performance, which can lead to increased emissions and reduced efficiency in the vehicle's emissions control system.
Common Causes of P208B
- Malfunctioning reductant pump
- Wiring issues
- Faulty reductant pump control module
- Sensor malfunction
- Issues with the SCR system
Symptoms of P208B
- Check Engine Light illuminated
- Reduced engine power
- Poor fuel efficiency
- Increased emissions
- Difficulty starting the vehicle
How to Fix P208B
- Diagnose the specific cause of the code by performing a thorough inspection of the reductant pump, wiring, sensors, and SCR system.
- Replace the reductant pump if it is found to be faulty.
- Repair or replace any damaged wiring or connectors.
- Test and replace any malfunctioning sensors.
- Reset the fault codes and test drive the vehicle to ensure the issue has been resolved.
Cost to Fix P208B
The cost of repairing a P208B code can vary depending on the specific cause of the issue and the labor rates in your area. Typically, replacing a reductant pump can cost between $200 and $600, while addressing wiring or sensor issues may range from $100 to $300. It's important to factor in diagnostic time and labor rates, which can vary between $80 and $150 per hour. Overall, the total repair cost for this issue could range from $300 to $1000, depending on the extent of the problem and the parts needed for the repair.
