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. From that point, we will review with you any troubleshooting steps that may need to be taken and other areas or systems that can be checked to rule out external problems contributing to your part's issue.

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 DEF (Diesel Exhaust Fluid) sensor monitors fluid level, temperature, and quality to ensure your emissions system operates correctly. A failing sensor can lead to false warnings, engine derates, or emissions compliance issues. Knowing how to test the DEF sensor can help you catch problems early and avoid unnecessary downtime.

Steps to Test a DEF Sensor:

  • Use a Diagnostic Scan Tool – Connect a scan tool to read live DEF sensor data, including fluid level, temperature, and quality readings.

  • Check for Fault Codes – Look for any active or stored DEF system-related Diagnostic Trouble Codes (DTCs) that may indicate sensor malfunction.

  • Compare Sensor Readings to Actual Conditions – Verify that sensor readings match the actual DEF fluid level and temperature. Discrepancies may point to sensor failure.

  • Inspect for Crystallization – Check the DEF tank and sensor area for white crystals, which can interfere with accurate sensor function.

  • Examine Wiring and Connectors – Visually inspect the sensor harness for damaged wires, corrosion, or loose connections that may disrupt signals.

  • Monitor Warning Lights – Persistent DEF system warnings or derates may indicate an underlying sensor issue requiring further inspection.

  • Perform OEM-Specific Tests – Some manufacturers provide software tests or DEF sensor override functions to help verify sensor operation more accurately.

Testing your DEF sensor involves both visual inspection and electronic diagnostics. If you notice inconsistent readings, fault codes, or system warnings, it’s important to address the issue promptly. Early detection helps maintain proper emissions system function and prevents costly repairs or unexpected engine derates.

Extreme temperatures, DEF contamination, and electrical issues can impact sensor performance.

Routine inspection for buildup, contamination, and electrical integrity helps maintain sensor accuracy.

Gentle rinsing with distilled water may remove buildup and restore sensor performance.

Harsh chemicals, abrasive tools, or high-pressure sprays should be avoided to protect sensitive sensor components.
