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.
"This Product Doesn't Have a Core"
Built for 2018–2024 Cummins X15 and X12 applications, the Differential Pressure Sensor with OEM 5492073 is a vital part of the diesel exhaust aftertreatment system. This sensor is engineered to measure pressure differences across the diesel particulate filter (DPF) and provide accurate data to the engine control module (ECM) for emissions system management. By tracking pressure changes before and after the DPF, it helps the ECM determine filter loading and regeneration needs. Reliable differential pressure feedback supports the proper timing of aftertreatment functions and can help reduce the likelihood of diagnostic fault codes tied to emissions performance. This page provides application-specific information to assist with identifying the Cummins X15 & X12 Differential Pressure Sensor 2018–2024 (OEM 5492073) for service and replacement needs.

The Cummins X15 / X12 Differential Pressure Sensor, OEM 5492073, is an aftertreatment monitoring sensor used on 2018–2024 applications. Its main job is to measure exhaust pressure before and after a filter component (typically the DPF), then report the difference to the engine control module (ECM).
That pressure difference tells the ECM how restricted the aftertreatment system is and how much soot has likely built up.
What OEM 5492073 does
- Measures pressure on two sides of the DPF/aftertreatment system
- Calculates differential pressure (restriction level)
- Helps determine soot loading inside the DPF
- Supports regeneration timing (when the system should clean the DPF)
- Helps detect problems like clogging, exhaust leaks, or sensor/hose issues
- Triggers fault codes and warning lights if readings are abnormal
In short, the Cummins differential pressure sensor (OEM 5492073) helps the engine monitor filter restriction and manage regeneration, protecting the aftertreatment system and keeping exhaust flow stable.
The main cause of dosing module failure is DEF crystallization and contamination, which clog internal passages and damage the dosing components over time.
A dosing module (DEF dosing system) is responsible for delivering the correct amount of DEF into the exhaust stream. When DEF dries or becomes contaminated, it forms deposits that restrict flow and cause inaccurate dosing—eventually leading to module failure.
The most common causes of dosing module failure include:
- DEF crystallization (most common)
- DEF dries inside the module, injector, or lines and forms hard crystals that clog valves and passages.
- Contaminated or poor-quality DEF
- Dirt, minerals, water dilution, or DEF mixed with other fluids can damage the system and cause internal corrosion or blockage.
- Leaking or dripping doser/injector
- DEF dripping when it shouldn’t leads to rapid crystal buildup and restriction.
- Faulty heaters or frozen DEF
- If DEF freezes and the heating system fails, it can stress the pump/module and create dosing errors.
- Electrical issues
- Damaged wiring, corrosion in connectors, or voltage problems can cause module communication and dosing failures.
- Exhaust temperature problems
- Low exhaust temps can prevent proper DEF atomization, leading to deposits and buildup near the injection point.
Dosing modules fail mainly because DEF crystallizes or becomes contaminated, which leads to clogging, corrosion, and incorrect DEF delivery.
Erratic pressure readings and recurring aftertreatment warnings can indicate a failing sensor.
Yes, without accurate pressure data the system can’t properly assess DPF condition.
A failed sensor can lead to incorrect DPF restriction readings and associated fault codes.
Yes, incorrect pressure readings can interfere with the timing of DPF regeneration.
