We will do everything we can to make sure that you get the service you need. We understand how important it is to receive your order as quickly as possible.
In most cases Tamerx Diesel Products only needs one address, as long as your product is shipping to the same location as your billing information. In order to eliminate credit card fraud, your billing information must match the credit card you provide.

Tamerx Diesel Products provides a replacement warranty on all of our parts. The duration and mileage limitations of the warranty vary by product and are specified on the product's detail page/item listing.

Please note that the warranty covers replacement of the part and the cost of shipping the replacement part to you only. It does not cover any shop, labor, towing, or any similar or related costs. This is not a "money back guarantee".

If you experience a problem with your part or it is not functioning properly, the correct warranty procedure is to call us at (510) 257-1777 (8:00 AM - 5:00 PM ET Monday through Friday). Be sure to have your order number and/or other relevant order information ready so we can easily locate your order and resolve your issue as quickly as possible.

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.

Diesel Exhaust Fluid (DEF) sensors play a crucial role in monitoring the quality, level, and temperature of DEF within the emissions system. When they fail, your engine can go into derate mode or display warning messages, leading to downtime and costly repairs. Fortunately, with the right maintenance practices, you can extend the life of your DEF sensor and ensure continued compliance with emissions regulations.

Best Practices to Prolong DEF Sensor Life:

  • Use High-Quality DEF – Always use certified, ISO 22241-compliant DEF to prevent contamination that can damage the sensor.

  • Keep the DEF Tank Sealed – Prevent exposure to air, dirt, or moisture by keeping the DEF tank cap tightly closed at all times.

  • Avoid Contaminated Containers – Refill only with clean equipment; dirty funnels or jugs can introduce harmful debris into the tank.

  • Store DEF Properly – DEF should be stored between 12°F and 86°F to avoid crystallization or degradation, which can affect sensor readings.

  • Inspect for Crystallization – White crystal buildup on the sensor or around the tank opening can interfere with sensor accuracy and should be cleaned carefully.

  • Limit Idle Time in Cold Weather – Long idling periods in freezing temperatures can cause DEF to freeze, putting stress on the sensor components.

  • Schedule Regular Inspections – Include the DEF system in routine maintenance to catch early signs of sensor or system issues.

Keeping your DEF sensor in good working condition is all about clean fluid, careful handling, and regular system checks. By following these maintenance practices, you can reduce the risk of premature failure, avoid engine derates, and keep your emissions system running efficiently. A little preventive care goes a long way toward long-term reliability.

Incorrect data may trigger fault codes or cause the vehicle to enter reduced power mode.

You may notice DEF warning lights, error codes, or erratic DEF level displays on the dashboard.

 

The sensor typically self-calibrates, but certain vehicle systems may allow recalibration via diagnostic tools.

Its operational lifespan usually ranges from 3 to 5 years depending on DEF quality and environmental conditions.
