As is the case for the majority of the diesel products sold on Tamerx Diesel Products, your part's warranty is active as soon as you install it. In some other cases, warranty activation is contingent upon you sending us your core (i.e., your old part). Tamerx Diesel Products will provide you a return shipping label for parts that have a warranty with a core return condition. When we have received your core return, the part's warranty coverage begins. We reserve the right to void the product warranty if your core is not received within the allotted time, or if it isn't received at all. If the warranty for the diesel part you are purchasing has a core return requirement, it will be clearly noted on the product detail page/item listing.
What is a Core Charge?
A core charge (also called "core deposit") is similar to the deposit you might pay for a can or bottle of soda and is a standard requirement in the auto parts industry. For example, in many states, to promote recycling, you pay a deposit when you purchase a can of soda and receive your deposit back when you return the empty can. Many automotive parts have a core charge, or core price, that works in essentially the same way as a soda can deposit.
30 Day Core Charge Hold
You authorize Tamerx Diesel Products, to hold your credit card for the specified core charge amount and that you agree to return your core with 30 days of receiving the purchased part. When we have received your core return, the hold is released and the core charge payment is canceled.

The OEM 5100041353 DEF sensor is a vital component in Wacker Neuson machines using Deutz engines (2013–2021). It sits within or on the DEF (Diesel Exhaust Fluid) system and enables the engine control and aftertreatment systems to monitor the status of the DEF fluid and make necessary adjustments to maintain clean exhaust and proper emissions performance.
Purpose & Role
- Monitor DEF Level
- The sensor measures how much Diesel Exhaust Fluid remains in the tank, allowing the control system to know when fluid levels are low and to signal refills or trigger alerts.
- Track Fluid Temperature and Condition
- It senses the temperature of the DEF fluid to detect conditions like freezing or excessively high temperatures, which could compromise the fluid’s effectiveness.
- Support Emissions Control
- By providing accurate data about fluid levels and temperature, the sensor allows the engine’s emission controller or ECM to manage DEF dosing, regeneration, and system diagnostics properly.
- Enable Diagnostic Checks
- The sensor’s feedback helps the system detect faults (for example, low fluid, sensor drift, or failure) so it can alert the operator or take protective measures.
The 5100041353 DEF sensor acts as the monitoring “eye” of the DEF system in Wacker Neuson / Deutz engines. It provides the necessary data for the control system to manage fluid levels, temperature, and emissions — a crucial role in keeping the aftertreatment system effective and the machine emission-compliant.
The DEF (Diesel Exhaust Fluid) sensor plays a crucial role in your vehicle’s emissions system. It measures fluid level, quality, and temperature, sending this information to the Engine Control Module (ECM). When it starts to fail, your truck’s performance and compliance can quickly be affected. Knowing the warning signs of a bad DEF sensor helps you act before the system enters derate mode.
Common Signs of a Faulty DEF Sensor
If your DEF sensor is failing, you may notice one or more of the following:
- DEF system fault codes appearing on your dashboard
- Check engine light or emissions warning light
- Incorrect DEF level readings, such as “empty” when the tank is full
- Fluctuating or erratic gauge readings
- Premature derate countdowns, limiting engine power and speed
- Reduced efficiency or inconsistent performance
How to Confirm a Faulty DEF Sensor
- Scan for Diagnostic Trouble Codes (DTCs)
- Codes like P203B, P207F, or P205B often point to sensor-related issues.
- Inspect the DEF tank
- Look for contamination, crystallization, or debris that may interfere with sensor readings.
- Check wiring and connectors
- Corroded or damaged connections can mimic sensor failure.
- Compare readings
- If the DEF level on your dashboard doesn’t match the actual tank level, the sensor may be failing.
- Consult a technician
- A diagnostic scan can confirm whether the issue lies with the sensor or the head unit.
The DEF sensor is part of the sealed DEF head unit and is not serviceable or repairable. If it’s confirmed faulty, replacement is the only reliable solution.
A faulty DEF sensor can lead to inaccurate readings, warning lights, and derate mode if ignored. If you notice irregular DEF readings or emissions alerts, have the system diagnosed immediately to prevent downtime and maintain emissions compliance.
The DEF gauge may display full or empty continuously, or fault codes will appear on the diagnostic screen.
Yes, damaged or corroded wiring connectors often cause false readings or loss of signal.
Yes, contaminated or expired DEF fluid can cause sensor fouling and corrosion.
The system will trigger a check engine light, log a fault, and possibly activate derate mode.
