Возможные симптомы
Датчик уровня состоит из четырех цапф из высококачественной нержавеющей стали. Длина каждого штифта определяет уровень (высоту) бака, который необходимо проверить. Только три пина могут быть использованы для оценки уровня. Четвертый контакт используется как контакт заземления. Из-за электрической проводимости мочевины датчик уровня будет определять, находится ли уровень в баке выше или ниже соответствующего положения датчика уровня. Эта информация будет непосредственно оценена ECU.

OBD-II Trouble Code — P203F — Data Sheet
P203F — Reducer level too low.
What does DTC P203F mean?
This is a generic powertrain diagnostic trouble code (DTC) and is commonly applied to OBD-II vehicles. Car brands may include, but are not limited to, BMW, Mercedes Benz, VW Volkswagen, Sprinter, Ford, Audi, Dodge, Ram, GMC, Chevrolet, Jeep, etc.
Did you know that the engine light comes on when the engine exhaust emissions are out of specification? The ECM (Engine Control Module) monitors and regulates dozens of sensors, valves, systems, etc. It basically acts as a built-in emission check station. It not only monitors what your engine is consuming, but more importantly for the manufacturer, what your engine is emitting into the atmosphere.
This is relevant here because for the most part reductant level sensors are present on diesel vehicles with a DEF (diesel exhaust fluid) storage tank. DEF is a urea solution used in diesel engines to burn exhaust gases, which in turn reduces overall vehicle emissions, which, as mentioned earlier, is one of the most important goals of ECM. The reductant level sensor informs the ECM of the level of DEF in the storage tank.
P203F is a DTC defined as Reductant Level Too Low which indicates that the DEF level in the tank is too low as determined by the ECM.
Reducing agent tank DEF: 
What is the severity of this DTC?
I would say that this is pretty minor code considering the possibilities. Basically, we are talking about a malfunction of a system that monitors what happens after it has already been burned and used. However, emission standards in most states / countries are quite strict, so it is advised to address this issue before it causes more damage to your vehicle, let alone the atmosphere!
What are some of the symptoms of a P203F code?
Symptoms of the P203F diagnostic code may include:
- Incorrect DEF (Diesel Exhaust Fluid) level reading
- Exhaust emissions out of specification
- CEL (check engine light) on
- Excessive smoke
- Low or other DEF warning on instrument cluster.
- There is a suspicious increase in exhaust smoke
- The DEF warning light is on your vehicle’s instrument cluster.
- The DEF (Diesel Exhaust Fluid) reading is not accurate.
- Your vehicle’s exhaust emissions do not meet manufacturer’s specifications.
What are some of the common causes for the code?
Reasons for this P203F engine code may include:
- Reductant level sensor defective
- Wrong liquid in DEF storage tank
- DEF is low and needs to be replenished.
- Short circuit near the sensor
What are the steps to diagnose and troubleshoot a P203F?
The first step in the process of troubleshooting any problem is to review technical service bulletins (TSBs) for known problems with a particular vehicle.
Advanced diagnostic steps become very vehicle specific and may require appropriate advanced equipment and knowledge to be performed accurately. We outline the basic steps below, but refer to your vehicle / make / model / transmission repair manual for specific steps for your vehicle.
Basic step # 1
Be sure to completely erase all active codes and test drive the vehicle before diagnosing any existing codes. This will clear any codes that remained active after repairs or other periodic, less important codes. After a test drive, re-scan the vehicle and continue diagnosing only with active codes.
Basic step # 2
I am sure that after you own your vehicle for a considerable amount of time, you know where the DEF (Diesel Engine Exhaust Fluid) storage tank is. If not, then I saw them in the trunk as well as under the car. In this case, the filler neck of the storage tank should be easily accessible either in the trunk or next to the filler neck for fuel. First of all, make sure you differentiate it to avoid getting unwanted liquid into unwanted places. If you can check your level mechanically with a dipstick, do so. On the other hand, some vehicles have no other way to check the DEF level other than directing the flashlight into the hole to visually see if there is a DEF there. You will want to top up anyway, especially if P203F is present.
Basic step # 3
Depending on the capabilities of your OBD2 code scanner / scanner, you can electronically monitor the sensor using it. Especially if you know the storage tank is full of DEF and the readings show something else. In this case, it is most likely that the reductant level sensor is defective and needs to be replaced. This can be tricky considering the fact that it will be installed on a tank. When replacing a sensor, make sure you catch any DEF that comes out.
Basic step # 4
If you can easily access the reductant level sensor connector, make sure it provides a good electrical connection. In addition, it is always advisable to consult the manufacturer’s service data for specific values and testing procedures for a level sensor to ensure it is defective before replacing it. You will most likely need a multimeter for this, as resistance tests may be required. Compare the actual values available with the manufacturer’s desired values. If the values are outside the specification, the sensor must be replaced.
NOTE: Always follow the manufacturer’s instructions for when to disconnect the battery, precautions, etc.
Basic step # 5
Inspect the reductant level sensor wiring harness for damage or abrasion, this may send erroneous readings to the ECM and may force you to replace the sensor when not necessary. Any exposed wires or corrosion must be repaired before proceeding. Make sure the harness is secure and does not come into contact with moving parts.

Volvo vehicles, like any other vehicles, also generate many unwarranted error codes. Error codes often occur in heavy duty vehicles due to high torque and high load. The error codes most frequently encountered by users are from from the Adblue system.
When we say Adblue systems, we often think about system that breaks very easily. These systems are often used in heavy loads and commercial vehicles. Lately, it has begun to be used in passenger cars. these systems are not used in most countries, even if they are mandatory in Europe. Because it is not structured correctly. Even the adblue liquid, that this system uses, is very difficult to find on the market. Like we said, the system is unstable and users are having trouble. It is a very difficult situation when the systems breaks in the middle of road . Repair of the system is very costly and you lose precious time. For this reason, users are often looking for solutions. One of the solution is an Adblue Emulator developed by SAIL TECHNOLOGY. It is a permanent solution and will be there right beside you in every situation. Adblue Emulators, which many users prefer, will not let you down.
So what do these emulators do and what information do they give? Below are the benefits and fault code information of the SAIL Technology Adblue Emulator we have listed for you.
The instructional models are designed for: Volvo B11R (3), Volvo B5LH (3), Volvo B5TL (3), Volvo B8R (3), Volvo FH (4).
