Code P207F Ford Description

The aftertreatment system is equipped with two Nox Sensors and modules. The upstream NOx Sensor 1/1 is located on the Turbocharger elbow downpipe and is permanently connected to a corresponding Nox Sensor Module mounted to the hot side of the engine block. The downstream NOx Sensor 1/2 is located at the outlet of the SCR Catalyst and is permanently connected to a corresponding Nox Sensor Module which is mounted on the right frame rail. The NOx Sensors and NOx Sensor Modules are calibrated to each other and must be replaced as an assembly. The two NOx Sensor and Module assemblies are not interchangeable. The NOx Sensor Modules are smart devices and communicate with the Powertrain Control Module (PCM) over the J1939 Data Link. The NOx Sensor Modules perform their own internal diagnostics and report malfunctions back to the PCM. The NOx Sensors are used to monitor the efficiency of the SCR Catalyst and dosing system. The PCM will illuminate the Malfunction Indicator Lamp (MIL) after the diagnostic runs and fails in two consecutive drive cycles. The PCM will turn off the MIL immediately after the monitor runs and passes.

Frequently Asked Questions about P207F Ford Code

1. What does the OBDII code P207F mean on a Ford vehicle?

P207F indicates a "Reductant Quality Performance" issue, meaning the vehicle's Powertrain Control Module (PCM) has detected a problem with the quality of the Diesel Exhaust Fluid (DEF) in the emissions system.

2. What are common symptoms of the P207F code?

Symptoms may include a Check Engine Light, DEF warning messages, reduced engine performance, or the vehicle entering a limp mode if the issue is not addressed.

3. What causes the P207F code on a Ford?

Common causes include contaminated or poor-quality DEF, an empty DEF tank, a malfunctioning DEF quality sensor, or issues with the SCR (Selective Catalytic Reduction) system.

4. Can P207F be caused by using the wrong DEF fluid?

Yes, using DEF that doesn’t meet ISO 22241 standards or is contaminated can trigger the P207F code.

5. How can I fix the P207F code on my Ford?

Start by draining and refilling the DEF tank with fresh, high-quality DEF. If the code persists, inspect the DEF quality sensor, SCR system, and related wiring for faults.

6. Can I drive with the P207F code active?

Driving is possible in the short term, but ignoring the issue could lead to reduced engine power or the vehicle entering limp mode, so it’s best to address it promptly.

7. How do I reset the P207F code after repairs?

Use an OBDII scanner to clear the code after fixing the issue. If the problem isn’t resolved, the code will likely return.

8. Is the P207F code covered under Ford’s warranty?

This depends on your vehicle’s age, mileage, and warranty terms. DEF system components may be covered under the emissions warranty.

9. Can cold weather cause the P207F code on a Ford?

Cold weather can cause DEF to freeze, potentially triggering the code if the system cannot properly detect DEF quality. However, the system is designed to handle freezing conditions, so this is uncommon.

10. How much does it cost to repair a P207F code on a Ford?

Repair costs vary but typically range from $100 to $1,000, depending on whether the issue is resolved by replacing the DEF fluid or repairing/replacing components like the DEF quality sensor or SCR system.
