This summary uses the existing diagnostic information shown in full below.
This code means that a part in the car that helps clean the exhaust is stuck and can't open. It's like a door that should open to let air out, but it's jammed shut.
The reductant purge control valve is part of the vehicle's emissions system. It helps control the flow of a special fluid that reduces pollution. When the valve is stuck closed, it can't do its job properly.
The P24E0 code indicates that the reductant purge control valve 'B' is stuck in the closed position. This valve is part of the diesel exhaust fluid (DEF) system, which helps reduce nitrogen oxide emissions in diesel engines. A stuck valve means that the DEF cannot be purged properly, leading to potential emissions issues.
• Check engine light is on
• Poor engine performance
• Increased emissions
• Faulty reductant purge control valve
• Electrical issues such as damaged wiring or connectors
• Blockage in the DEF system
DEF: Diesel Exhaust Fluid, a fluid used to reduce emissions in diesel engines
Emissions: Pollutants released into the air from the vehicle's exhaust
• Use an OBD-II scanner to confirm the code
• Inspect the reductant purge control valve for physical damage or blockages
• Check the wiring and connectors for any signs of damage
• Replace the reductant purge control valve if faulty
• Repair or replace damaged wiring or connectors
• Clear any blockages in the DEF system
• OBD-II scanner
• Multimeter
• Basic hand tools

Moderate
• Ford F-250
• Chevrolet Silverado 2500
• Ram 2500
• Regularly inspect the DEF system
• Use high-quality DEF fluid
• Perform routine vehicle maintenance
Emissions System Issue
• Have the vehicle inspected by a professional mechanic
• Avoid driving the vehicle excessively until repaired
Check with your vehicle manufacturer; emissions-related components may be covered under warranty.
This code has become more common as emissions regulations have tightened, requiring more complex DEF systems.
Moderate – While not immediately dangerous, it should be addressed to avoid increased emissions and potential fines.
Driving with a malfunctioning emissions system can lead to increased pollution and may not comply with emissions regulations.
• Engine at operating temperature
• Vehicle in a safe, stationary position
The reductant purge control valve is typically located near the DEF tank or along the DEF line.
Q: Can I drive my car with a P24E0 code?
A: It's best to get it fixed soon. Driving with this issue can increase emissions and may cause other problems over time.
Q: What happens if I ignore this code?
A: Ignoring it can lead to increased pollution, possible fines, and further damage to the emissions system.
