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"
Designed for 2024–2027 Cummins X15 applications, the Temp Sensor (OEM 5654179) is an essential component of the engine and emissions management system. This sensor is engineered to monitor key temperature readings—such as exhaust or intake air temperature—and send accurate data to the engine control module (ECM). Reliable temperature feedback helps the ECM manage combustion control, fuel delivery, and aftertreatment functions across varying operating conditions. Proper sensor operation can also help reduce the likelihood of warning lights, diagnostic fault codes, or drivability concerns related to temperature monitoring. This page provides application-specific information to assist with accurate identification of the Cummins X15 Temp Sensor OEM 5654179 for service and replacement needs.

The Cummins X15 Temp Sensor (2024–2027), OEM 5654179 works by measuring temperature at a specific engine or aftertreatment location and sending that information to the engine control module (ECM). The ECM uses this data to manage system operation and protect components from overheating.
How it works (step-by-step)
- 1) The sensor detects temperature changes
- Once installed, the sensor tip is exposed to the temperature it is monitoring (such as coolant, intake air, or exhaust temperature depending on application).
- 2) Internal thermistor changes resistance
- Inside the sensor is a thermistor, a temperature-sensitive element. As temperature increases or decreases, the thermistor’s resistance changes in a predictable way.
- 3) Signal is sent to the ECM
- The ECM supplies a reference voltage to the sensor and reads the return voltage. This change in signal tells the ECM the exact temperature.
- 4) ECM uses the reading to control and protect systems
- The ECM uses the sensor data to:
- monitor operating temperature in real time
- support engine protection strategies
- assist aftertreatment control (when applicable)
- trigger fault codes or warning lights if readings are out of range
- The ECM uses the sensor data to:
OEM 5654179 functions by converting temperature into an electrical signal, giving the Cummins X15 ECM the information it needs for safe, reliable operation in 2024–2027 applications.
No, a temperature sensor should not be reused after professional servicing, and it’s recommended to replace it instead.
Temperature sensors are precision electrical components. Once they start failing, the problem is usually internal—such as electrical drift, corrosion, moisture intrusion, or heat damage. Servicing may clean the outside or connector, but it cannot restore accurate readings or long-term reliability.
Why reusing a serviced temp sensor is not recommended
- Recurring fault codes and warning lights
- Incorrect or unstable temperature readings
- Cooling fan issues (running constantly or not activating)
- Regeneration failures (if it’s an exhaust temp sensor)
- Derate / restricted mode returning
- Short and unpredictable remaining service life
No—a temp sensor should not be reused after servicing. For dependable operation and to prevent repeat issues, replacement is the correct recommendation.
Erratic temperature readings or repeated aftertreatment warnings often indicate sensor issues.
It uses the temperature data to adjust aftertreatment timing and monitor system health.
Yes, accurate temperature monitoring supports proper aftertreatment operation needed for emissions standards.
It works alongside NOx and differential pressure sensors for complete aftertreatment monitoring.
