This code means that the computer in your car found a problem with the sensor that checks the temperature inside a special box that helps clean the car's exhaust. It's like when a thermometer doesn't work right and gives the wrong temperature.
The P06F1 code indicates an issue with the internal temperature sensor of the reductant control module, which is responsible for monitoring and controlling the temperature of the reductant system.
The reductant control module is part of the vehicle's emissions control system, specifically for diesel engines equipped with Selective Catalytic Reduction (SCR). The internal temperature sensor within this module ensures the reductant (often urea-based DEF) is at the correct temperature for optimal performance. If the sensor reads outside expected parameters, it triggers the P06F1 code.
• Check Engine Light is on
• Reduced engine performance
• Increased emissions
• Faulty internal temperature sensor
• Wiring issues such as shorts or open circuits
• Faulty reductant control module
Reductant: A substance, often urea-based, used in SCR systems to reduce emissions.
SCR: Selective Catalytic Reduction, a system used in diesel engines to reduce emissions.
• Use an OBD-II scanner to confirm the code
• Inspect the wiring and connectors for damage
• Test the internal temperature sensor for proper operation
• Replace the faulty temperature sensor
• Repair or replace damaged wiring
• Replace the reductant control module if necessary
• OBD-II scanner
• Multimeter
• Basic hand tools

Moderate
• Ford F-250 Super Duty
• Chevrolet Silverado 2500HD
• Ram 2500
• Regular maintenance of the emissions system
• Ensure proper DEF levels and quality
• Inspect wiring and connectors regularly
Sensor Issue
• Do not ignore the Check Engine Light
• Consult a professional mechanic if unsure
• Avoid driving long distances until resolved
Check with the vehicle manufacturer for emissions-related warranty coverage.
This code has become more common with the increased use of SCR systems in diesel vehicles to meet stringent emissions standards.
Moderate – Addressing this issue is important to maintain vehicle performance and emissions compliance.
Ignoring emissions-related issues 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 in the engine compartment.
Q: Can I drive with a P06F1 code?
A: It's possible to drive short distances, but it's best to fix the issue soon to avoid further problems.
Q: Will this code affect my vehicle's emissions test?
A: Yes, a P06F1 code can cause your vehicle to fail an emissions test.
