This code means there's a problem with the temperature sensor inside the part of the car that helps clean the exhaust. It's like if a thermometer in your house wasn't working right.
The P06F0 code indicates an issue with the internal temperature sensor circuit of the reductant control module, which is responsible for managing the temperature of the diesel exhaust fluid (DEF).
The reductant control module monitors and controls the temperature of the diesel exhaust fluid to ensure it is at the optimal temperature for reducing emissions. The internal temperature sensor provides feedback to the module, and if the circuit is faulty, it can affect the module's ability to regulate the DEF temperature.
• Check Engine Light illuminated
• Possible reduction in engine performance
• Increased emissions
• Faulty internal temperature sensor
• Wiring issues such as shorts or open circuits
• Defective reductant control module
Reductant: A substance used to reduce emissions, often diesel exhaust fluid.
DEF: Diesel Exhaust Fluid, a liquid used to reduce emissions in diesel engines.
• Scan the vehicle for additional codes
• Inspect wiring and connectors for damage
• Test the internal temperature sensor for proper operation
• Replace the faulty internal temperature sensor
• Repair or replace damaged wiring or connectors
• Replace the reductant control module if necessary
• OBD-II scanner
• Multimeter
• Basic hand tools

Moderate
• Ford F-250
• Chevrolet Silverado
• Ram 2500
• Regular maintenance of the DEF system
• Ensure proper DEF fluid levels
• Inspect wiring and connectors periodically
Sensor Issue
• Address the issue promptly to avoid increased emissions
• Consult a professional mechanic if unsure about repairs
Check with the vehicle manufacturer for warranty coverage on emissions-related components.
This code is relatively common in diesel vehicles equipped with DEF systems, especially as they age.
Moderate – It should be addressed soon to prevent potential emissions issues.
Ignoring emissions-related codes can lead to failing emissions tests and potential fines.
• Engine at operating temperature
• Vehicle in a safe, stationary position
The reductant control module is typically located near the DEF tank or exhaust system.
Q: Can I drive with a P06F0 code?
A: You can drive, but it's best to fix the issue soon to avoid emissions problems.
Q: Will this code affect fuel economy?
A: It might not directly affect fuel economy, but it can lead to increased emissions.
