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

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 Cummins B6.7 Exhaust Back Pressure Sensor (EBP) 2019-2025 OEM 4384678 plays a critical role in monitoring exhaust pressure and supplying real-time data to the engine management system. One of the most common topics diesel owners search for is how an Exhaust Back Pressure (EBP) sensor helps the emissions system operate correctly. Replacing a worn sensor with the correct OEM component helps maintain accurate pressure readings and reliable system communication.

  • OEM 4384678 is designed for 2019-2025 Cummins B6.7 applications, providing a factory-style fit for compatible vehicles.
  • Continuously monitors exhaust back pressure, supplying accurate data needed by the engine control module (ECM).
  • Supports proper operation of the exhaust aftertreatment system, helping related emissions components function as intended.
  • Helps the engine management system make accurate operating adjustments by delivering consistent pressure measurements.
  • Manufactured to OEM specifications, ensuring dependable compatibility with the original sensor mounting location and electrical connection.
  • Built to withstand high-temperature exhaust environments, providing reliable performance under demanding operating conditions.
  • Designed for long-term durability, making it a dependable replacement for restoring accurate exhaust pressure monitoring.

The Cummins B6.7 Exhaust Back Pressure Sensor (EBP) 2019-2025 OEM 4384678 is an essential replacement for maintaining accurate exhaust system monitoring. With its OEM fit, durable construction, and precise pressure sensing capabilities, it helps support dependable engine management and proper emissions system operation.

The exhaust back pressure sensor monitors pressure within the exhaust system and provides important data to the engine control module. This information helps manage turbocharger performance, DPF regeneration, and overall emissions control. While a vehicle may still run with a faulty sensor, continuing to drive without repairing it can lead to reduced performance and additional aftertreatment problems.

  • A faulty sensor can send inaccurate pressure readings, causing the engine control module to make incorrect adjustments.
  • The check engine light will often illuminate with exhaust or emissions-related fault codes.
  • DPF regeneration may become less effective or fail completely because the system cannot accurately monitor exhaust conditions.
  • Reduced engine power or engine derate mode may occur to protect the engine and emissions system.
  • Fuel consumption may increase as the engine compensates for incorrect pressure data.
  • Turbocharger performance can be affected if the engine control module receives inaccurate exhaust pressure information.
  • Prolonged operation with a faulty sensor can contribute to excessive soot buildup and additional stress on the DPF and other aftertreatment components.

Driving with a bad exhaust back pressure sensor may be possible for a short time, but it is not recommended. Prompt diagnosis and replacement help restore accurate system monitoring, improve engine performance, and protect the entire aftertreatment system from unnecessary damage.

 

Yes, soot and carbon deposits can block the sensor port and affect pressure readings. Cleaning or replacing the sensor may be necessary if buildup becomes excessive.

The sensor provides exhaust pressure data that helps the engine control module manage regeneration and other emissions functions. Accurate readings are important for proper aftertreatment performance.

Yes, damaged wiring, loose connectors, or corrosion can interrupt communication between the sensor and the engine control module. Electrical issues can produce symptoms similar to a failed sensor.

Accurate pressure readings allow the engine to properly manage combustion and emissions functions. Incorrect data can affect overall engine efficiency.
