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"
Start with reliable emissions monitoring using the Cummins X15 and ISX15 NOx Sensor 2013–2021, OEM Part Number 6304162. This sensor detects nitrogen oxide levels in the exhaust stream and provides critical feedback to the aftertreatment control system to help maintain proper emissions control. Built to meet OEM specifications, it ensures accurate fitment and dependable operation across a range of X15 and ISX15 engine applications. A malfunctioning NOx sensor can trigger warning lights, fault codes, or improper emissions regulation, making timely replacement important. Tamerx Diesel Products LLC supplies trusted diesel components to help keep your Cummins engine operating cleanly and consistently.

Accurate emissions monitoring is essential in modern diesel engines, and the Cummins X15, ISX15 NOx Sensor OEM 6304162 plays a critical role in that process. Designed for 2013–2021 applications, this sensor measures nitrogen oxide (NOx) levels in the exhaust system.
The primary role of the NOx sensor is to detect and report the concentration of nitrogen oxide gases in the exhaust stream. This information allows the engine control module (ECM) to adjust Diesel Exhaust Fluid (DEF) dosing and maintain proper Selective Catalytic Reduction (SCR) system performance.
The Cummins NOx Sensor OEM 6304162 is responsible for:
- Measuring NOx levels in the exhaust
- Sending real-time data to the ECM
- Supporting accurate DEF injection control
- Helping maintain emissions compliance
- Triggering diagnostic alerts if readings are out of range
The sensor is typically installed either upstream or downstream of the SCR catalyst. Upstream sensors measure NOx levels before treatment, while downstream sensors verify that the SCR system is effectively reducing emissions.
Based on the sensor’s readings, the ECM adjusts DEF dosing to ensure optimal NOx conversion without over-injecting fluid.
If the NOx sensor fails or provides inaccurate data, it can lead to incorrect DEF dosing, warning lights, or reduced engine operation modes.
The OEM 6304162 NOx sensor is engineered specifically for Cummins X15 and ISX15 engines, ensuring proper communication with factory control systems.
When functioning correctly, this sensor helps maintain effective emissions control, regulatory compliance, and dependable engine operation.
The NOx sensor monitors nitrogen oxide levels in the exhaust system and helps the SCR system adjust DEF dosing. When it fails, emissions control and engine operation can be affected.
There is no set replacement interval. Instead, a NOx sensor should be replaced when diagnostics confirm it is no longer providing accurate readings.
Common signs it may be time for replacement include:
- Check engine or SCR warning light
- Persistent NOx sensor fault codes
- Inaccurate or implausible NOx readings
- Increased DEF consumption
- Reduced engine operation or speed limitation
- Failed emissions testing
If fault codes return after clearing and wiring checks show no issues, the sensor itself may be failing.
Before replacing the NOx sensor, a thorough inspection is important. A technician will typically:
- Scan for stored diagnostic trouble codes
- Monitor live NOx readings
- Inspect wiring and connectors
- Verify proper DEF dosing and SCR operation
In some cases, SCR system issues or exhaust leaks can trigger similar codes. Confirming the root cause helps avoid unnecessary replacement.
If the sensor fails communication or response tests, replacement is usually required to restore proper emissions system function.
The Cummins 6304162 NOx Sensor is mounted in the exhaust aftertreatment system where it can monitor NOx levels in the exhaust flow.
Accurate NOx sensing helps the engine’s control system properly regulate diesel exhaust fluid (DEF) dosing and maintain emissions compliance.
Common signs include emissions system fault codes, illumination of emissions warnings, or reduced SCR system feedback accuracy.
Yes, the Cummins 6304162 is designed to integrate with the engine’s factory NOx wiring harness and emissions control components.
