P207F on Jeep
Reductant Quality Performance
P207F on Jeep vehicles indicates reductant quality performance. Au7o has documented this code across 1 Jeep model — most commonly on Grand Cherokee. This code applies to diesel vehicles with a Selective Catalytic Reduction (SCR) emissions system and means the quality of the diesel exhaust fluid (DEF, also called reductant or AdBlue) does not meet the required specification. The SCR system injects DEF into the exhaust to chemically neutralize nitrogen-oxide (NOx) pollutants, and the computer monitors NOx sensors and the DEF quality sensor to confirm the fluid is doing its job. When it concludes the reductant is contaminated, diluted, the wrong fluid, or not reducing emissions effectively, it sets this code. It generally indicates a DEF quality or SCR efficiency problem and often triggers reduced power or limited restarts to force the issue to be fixed. Typical repair costs on Jeep range from $900 to $2,500, depending on the specific model and root cause.
Common Causes of P207F
- •Contaminated, diluted, or wrong fluid in the DEF tank (e.g., water or fuel)
- •Poor-quality or expired/degraded DEF
- •Faulty DEF quality sensor
- •Failing or clogged DEF (reductant) injector
- •Faulty NOx sensor(s)
- •DEF system or exhaust leaks
- •Aged or damaged SCR catalyst

- 3.0L EcoDiesel DEF Tank/Heater/Pump Failure Triggering Limp Mode and No-Start Countdown2014-2016
The diesel-exhaust-fluid (DEF/reductant) system on the 3.0L EcoDiesel Grand Cherokee is a frequent failure point. The integrated DEF tank assembly bundles the pump, heater, and level/temperature/pressure sensors into one unit; when any single internal component fails (commonly the pump pressure or the tank heater), it sets emissions codes. Because Mopar does not sell the internal components separately, a single failure requires replacing the entire tank assembly. Critically, an unresolved DEF fault escalates to a speed-limited limp mode and ultimately a no-start once the dashboard mileage countdown expires, stranding the vehicle.

What does P207F mean on Jeep?▼
P207F stands for "Reductant Quality Performance." This code applies to diesel vehicles with a Selective Catalytic Reduction (SCR) emissions system and means the quality of the diesel exhaust fluid (DEF, also called reductant or AdBlue) does not meet the required specification. The SCR system injects DEF into the exhaust to chemically neutralize nitrogen-oxide (NOx) pollutants, and the computer monitors NOx sensors and the DEF quality sensor to confirm the fluid is doing its job. When it concludes the reductant is contaminated, diluted, the wrong fluid, or not reducing emissions effectively, it sets this code. It generally indicates a DEF quality or SCR efficiency problem and often triggers reduced power or limited restarts to force the issue to be fixed. On Jeep specifically, this code is documented across 1 model.
What causes P207F on Jeep vehicles?▼
Common causes on Jeep: Contaminated, diluted, or wrong fluid in the DEF tank (e.g., water or fuel), Poor-quality or expired/degraded DEF, Faulty DEF quality sensor, Failing or clogged DEF (reductant) injector, Faulty NOx sensor(s).
