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, 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 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 customer, or parts buyer, is responsible for any shipping costs associated with core returns unless otherwise specified in the product listing/detail page. Tamerx Diesel Products offers prepaid UPS shipping labels (SKU numbers UPS-CR1 and UPS-CR2) for use in returning your core that are available for purchase on our website during your shopping/order process.
The shipping label you will need to use for the core return is dependent upon what part you are purchasing. UPS-CR1 is good for cores weighing up to 20 pounds. UPS-CR2 is appropriate for shipping cores weighing 21 pounds or more. You must include enough information with the core return that clearly identifies it as a.) a Core Return, and b.) contains enough information we can use to clearly associate the core return with your order. Including a copy of the invoice or packing slip that came with the original shipment, clearly marked "Core Return", is ideal. Alternately, you can include a note marked as "Core Return" that includes your order number, full name and address, and phone number or other contact information. Failure to include this information with your returned core will most likely delay any due core credit being issued and/or delay any applicable warranty activation. Core returns need to be for the exact part purchased and cannot be damaged. Substituting another part in place of the part you have purchased is not acceptable.
All fluids must be drained.
If you have purchased a set or a parts package, you will need to return cores for all components of the set. For example, if you have purchaed a high pressure oil pump with an IPR valve, you will need to return both HPOP and IPR valve cores to receive proper credit. If you have purchased an EGR cooler/EGR valve package, your core return must consist of an EGR cooler core and an EGR valve core, or core credit will not be given.
Core Charges are often mandated by state legislature, and, as such, the actual core charge and taxes on the charge may vary depending on the state in which you buy your part. The Tamerx Diesel Products core charge presented to you online today with your item is representative of the most common core charge.

SCR warnings can originate from sensor faults or exhaust-treatment problems, making dependable NOx readings essential for diagnosis. The Cummins X15 NOx Sensor 2022–2026, OEM 5679700, measures nitrogen oxides in the exhaust and supplies information used by the engine’s emissions-control system.
-
Measures exhaust NOx levels: The sensor reports nitrogen oxide concentration, helping the control system monitor emissions during operation.
-
Supports SCR evaluation: Readings from sensors before and after the SCR catalyst help the system assess how effectively exhaust treatment reduces NOx.
-
Helps identify signal problems: Missing, unstable, or implausible readings can direct technicians toward sensor, wiring, or communication checks.
-
Requires proper warm-up: The sensing element must reach suitable operating conditions before its readings can be evaluated reliably.
-
Guides replacement decisions: Reviewing sensor data alongside fault codes helps distinguish a failed sensor from a DEF-dosing or catalyst issue.
-
Needs correct application matching: Confirm OEM 5679700, sensor position, connector configuration, and engine serial number before selecting a replacement.
Understanding the NOx sensor’s monitoring role helps buyers address SCR warnings with a clearer diagnosis. When ordering the Cummins X15 NOx Sensor from TamerX Diesel Parts, verify application compatibility and follow the applicable Cummins testing procedure before replacement.
A bad NOx Sensor can cause inaccurate nitrogen oxide (NOx) readings, emissions system warnings, and irregular diesel aftertreatment operation. Since NOx sensors monitor exhaust emissions and help the Engine Control Module (ECM) evaluate Selective Catalytic Reduction (SCR) efficiency, a malfunctioning sensor can interfere with emissions monitoring and trigger diagnostic trouble codes.
-
Check engine light activation: A defective NOx Sensor may trigger the check engine light when the ECM detects abnormal sensor readings, electrical faults, or communication problems.
-
SCR system warning messages: Emissions-related alerts may appear on the dashboard when the NOx Sensor provides unreliable data or stops communicating properly.
-
Engine derate conditions: Persistent NOx Sensor faults can activate emissions-related power restrictions, reducing acceleration and available engine power.
-
Inconsistent NOx readings: Abnormally high, low, frozen, or fluctuating NOx measurements may indicate sensor deterioration or an electrical problem.
-
Recurring diagnostic trouble codes: NOx Sensor heater, communication, or signal-related fault codes may return even after being cleared if the underlying issue remains unresolved.
-
DEF consumption irregularities: Certain sensor or SCR control problems may contribute to abnormal Diesel Exhaust Fluid (DEF) dosing behavior, depending on the vehicle's control strategy.
-
Failed emissions testing: Incorrect sensor feedback or undetected SCR system problems can contribute to emissions compliance issues, although a faulty sensor does not always mean actual NOx emissions are elevated.
A bad NOx Sensor can produce several symptoms that resemble SCR catalyst failure, DEF dosing problems, or other aftertreatment faults. Checking diagnostic trouble codes, monitoring live NOx readings, and inspecting sensor wiring and related SCR components can help confirm the problem and determine whether NOx Sensor replacement is necessary.
NOx measurements can be used to evaluate how effectively the SCR system reduces nitrogen oxide emissions. Abnormal readings may indicate reduced catalyst efficiency, incorrect DEF dosing, or another aftertreatment problem.
Yes. Excessive soot and exhaust contaminants can accumulate around the sensing element and interfere with normal measurements. Addressing combustion and aftertreatment problems may help reduce premature sensor deterioration.
The sensor's heating system helps its sensing element reach the temperature required for reliable NOx measurements. A heater malfunction may delay sensor operation or trigger diagnostic fault codes.
The engine control system may lose information needed for normal emissions monitoring and SCR diagnostics. Depending on the fault and operating conditions, this can activate warning indicators or emissions-related operating restrictions.
