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.
The customer, or parts buyer, is responsible for any shipping costs associated with core returns unless otherwise specified in the product listing/detail page. Tamerx Diesel Products offers prepaid UPS shipping labels (SKU numbers UPS-CR1 and UPS-CR2) for use in returning your core that are available for purchase on our website during your shopping/order process.
The shipping label you will need to use for the core return is dependent upon what part you are purchasing. UPS-CR1 is good for cores weighing up to 20 pounds. UPS-CR2 is appropriate for shipping cores weighing 21 pounds or more. You must include enough information with the core return that clearly identifies it as a.) a Core Return, and b.) contains enough information we can use to clearly associate the core return with your order. Including a copy of the invoice or packing slip that came with the original shipment, clearly marked "Core Return", is ideal. Alternately, you can include a note marked as "Core Return" that includes your order number, full name and address, and phone number or other contact information. Failure to include this information with your returned core will most likely delay any due core credit being issued and/or delay any applicable warranty activation. Core returns need to be for the exact part purchased and cannot be damaged. Substituting another part in place of the part you have purchased is not acceptable.
All fluids must be drained.
If you have purchased a set or a parts package, you will need to return cores for all components of the set. For example, if you have purchaed a high pressure oil pump with an IPR valve, you will need to return both HPOP and IPR valve cores to receive proper credit. If you have purchased an EGR cooler/EGR valve package, your core return must consist of an EGR cooler core and an EGR valve core, or core credit will not be given.
Core Charges are often mandated by state legislature, and, as such, the actual core charge and taxes on the charge may vary depending on the state in which you buy your part. The Tamerx Diesel Products core charge presented to you online today with your item is representative of the most common core charge.

In TEMSA vehicles powered by Cummins engines, the DEF Head Unit with OEM number 1430-ANE-01-01X is a critical component within the emissions control system. This part, often called a DEF header or “sensor head,” performs a number of roles to help the aftertreatment system function reliably and correctly.
Primary Responsibilities
- Fluid Monitoring
- The head unit monitors how much Diesel Exhaust Fluid (DEF) is present in the tank. If levels drop too low, it can signal the engine control module (ECM) to trigger warning alerts or restrict operation.
- Quality / Concentration Sensing
- It checks that the DEF is within acceptable chemical concentration and purity levels. If the fluid is contaminated or its concentration is outside predefined limits, it can flag faults or prevent improper dosing.
- Temperature Regulation
- Because DEF can freeze or become unstable at low temperatures, the head unit includes temperature sensing and often integrates heating circuits (using coolant flow or resistive heaters). This ensures the fluid remains usable under cold conditions.
- Fluid Delivery & Return Management
- It forms part of the header assembly that routes fluid from the tank to the dosing/injection side and returns any unused fluid back into the tank. This helps maintain consistent flow and pressure in the DEF system.
- Data Communication
- All sensor readings—level, temperature, and quality—are communicated to the engine’s control system (ECM). The ECM uses this information to decide how much DEF to inject, detect faults, and manage system behavior.
Why This Role Matters
Without a correctly functioning head unit:
- The system could misread DEF levels or quality, leading to faults or engine derate.
- The engine’s emissions control system might not operate within regulatory tolerances.
- In cold conditions, the DEF fluid could become unusable, causing system failure or shutdown.
In summary, the TEMSA Cummins DEF Head Unit OEM 1430-ANE-01-01X acts as the “brain and gatekeeper” of the DEF system: it monitors key fluid parameters, manages fluid routing, ensures temperature control, and communicates with the engine control system to support emissions compliance and reliable operation.
When your DEF (Diesel Exhaust Fluid) head unit fails, the first question many drivers ask is whether they can replace it themselves or if it requires a professional technician. The answer depends on your mechanical experience and the tools available.
Can You Do It Yourself?
Yes, in some cases a skilled driver can replace a DEF head unit. It typically involves:
- Draining the DEF tank safely
- Removing electrical connections from the old unit
- Unbolting the head unit from the tank
- Installing the new component and reconnecting sensors
While the steps sound simple, there are risks. Handling DEF improperly can lead to contamination, and reconnecting sensors incorrectly may cause system errors.
When to Call a Technician
If you’re not confident in handling emissions components, it’s best to have a certified technician do the work. Professional service ensures:
- Correct installation and calibration
- Proper handling of DEF fluid
- System resets to clear error codes
- Compliance with emissions regulations
You can replace a DEF head unit on your own, but for most drivers, having a technician perform the job is the safer, more reliable option.
Yes, by providing accurate DEF data, it helps keep the emissions system operating smoothly.
Yes, in some cases a failed unit may trigger restrictions that reduce or stop operation.
It sends sensor data from the DEF tank directly to the engine control module.
Using clean DEF fluid and keeping the DEF tank free of contaminants helps protect the unit.
