This summary uses the existing diagnostic information shown in full below.
This code means that the part of the car that helps reduce pollution, called the reductant pump, is stuck and won't turn off.
The reductant pump is responsible for supplying the diesel exhaust fluid (DEF) to the exhaust system to reduce emissions. If it's stuck on, it continuously pumps DEF, which can lead to issues.
P215D indicates that the Engine Control Module (ECM) has detected that the reductant pump B is stuck in the 'on' position. This could lead to excessive use of diesel exhaust fluid and potential damage to the emission control system.
• Check Engine Light is on
• Unusual exhaust smell
• Increased DEF consumption
• Faulty reductant pump B
• Wiring issues in the reductant pump circuit
• Defective ECM
Reductant: A substance used to reduce emissions, often diesel exhaust fluid.
ECM: Engine Control Module, the computer that controls engine functions.
• Use an OBD-II scanner to confirm the code.
• Inspect the wiring and connectors for damage.
• Test the reductant pump for proper operation.
• Replace the reductant pump B if faulty.
• Repair or replace damaged wiring or connectors.
• Reprogram or replace the ECM if necessary.
• OBD-II scanner
• Multimeter
• Wrench set

Moderate
• Ford F-250
• Chevrolet Silverado
• Ram 2500
• Regular maintenance of the emission system
• Ensure proper DEF quality
• Check wiring connections periodically
Emission Control System
• Do not ignore the Check Engine Light.
• Have the vehicle inspected by a professional if unsure.
• Avoid driving long distances until the issue is resolved.
Emission-related components may be covered under the vehicle's emissions warranty.
P215D is a relatively uncommon code, typically associated with vehicles using selective catalytic reduction (SCR) systems.
Moderate – Addressing the issue will prevent further emission system damage.
Driving with a malfunctioning emission system may violate emissions regulations.
• Vehicle at operating temperature
• DEF system primed and operational
The reductant pump is usually located near the DEF tank, often at the rear of the vehicle.
Q: Can I drive with a P215D code?
A: It's best to address the issue promptly to avoid further damage and emissions violations.
Q: What happens if I ignore this code?
A: Ignoring the code can lead to increased emissions, potential fines, and damage to the emission control system.
