The terms, conditions, and details of our warranty vary from product to product. Specific warranty details can be found below.
Tamerx 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, 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 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.

Incorrect exhaust pressure readings can occur when a faulty Aftertreatment Hose prevents pressure from reaching the related sensor accurately. Cracks, leaks, restrictions, heat damage, or loose connections can distort pressure signals and make the aftertreatment system appear to have a sensor or DPF problem.
- Cracked hoses: Small cracks can allow pressure to escape before it reaches the sensor.
- Loose connections: Poorly secured fittings or hose ends may cause pressure leaks and inconsistent readings.
- Internal restrictions: Soot, moisture, or debris inside the hose can restrict pressure transfer to the sensor.
- Heat damage: High exhaust temperatures may harden, weaken, or deform the hose over time.
- Abnormal sensor readings: A damaged hose can cause pressure values to appear unusually high, low, or inconsistent.
- DPF-related fault codes: Incorrect pressure information may trigger codes associated with DPF restriction, soot loading, or regeneration.
- Unnecessary sensor replacement: A faulty hose can sometimes resemble a failed pressure sensor if the hose is not inspected during diagnosis.
Checking the Aftertreatment Hose is an important part of diagnosing incorrect exhaust pressure readings. Inspecting it for leaks, blockages, damaged fittings, and heat deterioration can help identify the actual problem before replacing sensors or other aftertreatment components.
Possible signs include visible cracks, soot around connections, exhaust-related fault codes, warning lights, or abnormal pressure readings.
Yes. The hose operates around high exhaust temperatures, and prolonged heat exposure or inadequate heat protection can eventually contribute to deterioration.
Inspecting the hose can help identify leaks, restrictions, loose fittings, or physical damage that could interfere with aftertreatment monitoring.
Yes. Soot and exhaust deposits can accumulate in pressure-sensing passages and potentially restrict the flow of pressure information.
