This summary uses the existing diagnostic information shown in full below.
This code means that the part of the car that heats up the special fluid to clean the exhaust is using too much electricity.
The P214F code indicates that the current draw for the reductant heater A circuit is higher than expected, which could be due to a short circuit or a malfunctioning component.
The reductant heater is responsible for heating the diesel exhaust fluid (DEF) to ensure it flows properly and can be injected into the exhaust system. A high current condition suggests an electrical fault in the heater circuit, such as a short to ground or a failing heater element.
• Check engine light on
• Poor fuel efficiency
• Vehicle may not meet emissions standards
• Short circuit in the heater wiring
• Faulty reductant heater
• Corroded or damaged connectors
Reductant: A substance used to reduce emissions in diesel engines.
DEF: Diesel Exhaust Fluid, a solution used to reduce nitrogen oxide emissions.
• Scan the vehicle for codes and freeze frame data.
• Inspect the wiring and connectors for damage or corrosion.
• Test the reductant heater for proper resistance and operation.
• Repair or replace damaged wiring or connectors.
• Replace the reductant heater if faulty.
• Clear the codes and test drive to ensure the issue is resolved.
• OBD-II scanner
• Multimeter
• Basic hand tools

Moderate
• Ford F-250
• Chevrolet Silverado
• Ram 2500
• Regularly inspect the DEF system components.
• Ensure proper DEF fluid levels.
• Perform routine maintenance checks.
Sensor Issue
• Do not ignore the check engine light.
• Have the vehicle inspected by a professional if unsure.
• Regular maintenance can prevent such issues.
Check with the manufacturer for warranty coverage on emissions-related components.
This code has become more common with the introduction of DEF systems in diesel vehicles to meet emissions standards.
Moderate – It should be addressed soon to prevent emissions issues and potential damage.
Driving with this code may not comply with emissions regulations and could lead to fines.
• Engine running
• DEF system active
The reductant heater is typically located near the DEF tank or lines.
Q: Can I drive with a P214F code?
A: It's not recommended as it may lead to increased emissions and potential damage.
Q: How can I prevent this code from appearing?
A: Regular maintenance and inspections of the DEF system can help prevent this issue.
