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 2013–2018 Cummins ISL and QSL 8.9L applications, the Temp Sensor with OEM 5461635 plays an important role in both engine management and emissions aftertreatment systems. This sensor accurately measures critical temperature data—such as exhaust or intake air temperatures—and sends that information to the engine control module (ECM). Reliable temperature feedback helps the ECM make precise adjustments to combustion, fuel delivery, and aftertreatment functions, supporting efficient operation and emissions compliance across varying conditions. Proper sensor performance can also help reduce drivability issues and minimize the occurrence of warning lights or diagnostic fault codes. This page provides application-specific details to assist with identifying the Cummins ISL & QSL 8.9L Temp Sensor 2013–2018 (OEM 5461635) for service and replacement needs.

The Cummins ISL / QSL 8.9L Temp Sensor (2013–2018), OEM 5461635 functions by detecting temperature changes at its mounting location and sending that information to the engine control module (ECM). This allows the engine and emissions system to react to real-time operating conditions.
How it works (simple breakdown)
- 1) The sensor reads temperature at the source
- Once installed (coolant passage, intake, or exhaust-related location depending on application), the sensor tip is exposed to the temperature it is monitoring.
- 2) Internal thermistor changes resistance
- Inside OEM 5461635 is a thermistor, a temperature-sensitive element. As temperature rises, the thermistor’s electrical resistance changes in a predictable way.
- 3) ECM converts the signal into a temperature reading
- The ECM sends a reference voltage to the sensor and reads the return signal. Based on the resistance change, the ECM calculates the actual temperature.
- 4) ECM uses the data to control and protect the system
- The temperature reading is used to:
- regulate engine operation and fuel strategy
- support cooling system control
- help manage aftertreatment functions (if applicable)
- trigger warning lights or fault codes if temperatures are abnormal
- The temperature reading is used to:
The Cummins temp sensor OEM 5461635 works by converting heat changes into an electrical signal so the ECM can monitor and protect ISL and QSL 8.9L engines from 2013–2018.
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.
It measures exhaust gas or aftertreatment temperatures to help monitor system conditions.
It is mounted in the exhaust or aftertreatment section where temperature data is needed for monitoring.
Temperature data helps the engine control unit track aftertreatment conditions and control emissions functions.
The aftertreatment components, including DPF and SCR systems, use temperature data for correct operation.
