SHIPPING POLICY

Tamerx Diesel Products ships via UPS Ground. Next day air shipping can be arranged for a reasonable price of anywhere from $50.00 - $100.00 depending on the weight of the product and your location. 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.

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. If a replacement is determined to be necessary, we will then arrange for your replacement part to ship out ASAP and issue any necessary return shipping labels and/or documents.

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.

Accurate pressure monitoring is essential for maintaining proper function within a diesel engine’s aftertreatment system. The Cummins differential pressure sensor measures the pressure difference across components like the Diesel Particulate Filter (DPF), helping the engine control module (ECM) determine how well exhaust gases are flowing. This information plays a key role in managing emissions and keeping the system operating efficiently.

  • Measures Pressure Across the DPF
    The sensor monitors the difference in exhaust pressure before and after the DPF, providing insight into soot buildup and filter condition.
  • Supports Proper Regeneration Timing
    When pressure levels indicate increased soot accumulation, the sensor signals the ECM to initiate regeneration, helping clear the filter and restore normal exhaust flow.
  • Helps Maintain Balanced Exhaust Flow
    By tracking pressure changes, the sensor ensures that exhaust gases move through the system correctly, preventing restrictions that could affect engine operation.
  • Provides Critical Data to the ECM
    Real-time pressure readings allow the ECM to adjust system functions and maintain accurate emissions control across varying driving conditions.
  • Designed for Cummins Applications (2011–2024)
    Built to OEM 4383998 specifications, this differential pressure sensor is intended for compatibility with a wide range of Cummins engines, supporting proper integration with the aftertreatment system.

The differential pressure sensor is a small but essential component in the emissions system. By monitoring exhaust pressure and supporting regeneration processes, it helps maintain efficient aftertreatment performance and ensures reliable operation in Cummins-powered diesel applications.

A differential pressure sensor is an important component in modern diesel exhaust systems, especially in vehicles equipped with a Diesel Particulate Filter (DPF). It measures the difference in pressure between two points in the exhaust system, helping the engine control module determine how well exhaust gases are flowing. This information is essential for maintaining proper emissions control and system performance.

  • The sensor measures pressure before and after the DPF, allowing the system to detect soot buildup inside the filter.
  • As soot accumulates, the pressure difference increases, signaling the need for a regeneration cycle to burn off the buildup.
  • Accurate pressure readings help ensure regeneration occurs at the right time, preventing excessive clogging.
  • The sensor helps detect restrictions or blockages in the exhaust system that could affect performance.
  • Faulty readings can trigger warning lights or cause improper regeneration, leading to further aftertreatment issues.
  • The data collected supports overall emissions control by ensuring exhaust gases are properly processed through the system.

A properly functioning differential pressure sensor is essential for monitoring exhaust flow and maintaining DPF efficiency. Regular diagnostics and prompt attention to warning signs help ensure accurate readings and reliable operation of the entire aftertreatment system.

Yes, it can identify pressure changes that indicate restrictions or buildup.

The system may receive incorrect data, which can lead to poor performance or warning alerts.

Yes, it continuously monitors pressure differences while the system is operating.

Signs may include warning lights, incorrect readings, or reduced system efficiency.
