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 2018–2024 Cummins QSB 6.7L and B6.7 applications, the Temp Sensor with OEM 4384577 is an important component of 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, which supports 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 QSB 6.7L & B6.7 Temp Sensor 2018–2024 (OEM 4384577) for service and replacement needs.

The Cummins QSB 6.7L and B6.7 temperature sensor, OEM 5461627, is a vital monitoring component used in 2013–2018 diesel applications. Its main role is to provide accurate real-time temperature readings to the engine control module (ECM), helping the engine and emissions system operate safely and consistently.
This sensor measures temperature at a specific location depending on the engine configuration. It may be installed to monitor coolant temperature, intake temperature, or exhaust-related temperature in the aftertreatment system. As temperatures rise or fall, the sensor sends an electrical signal to the ECM, allowing the system to make quick adjustments when needed.
Accurate temperature data is critical because modern Cummins engines rely on sensor feedback to protect components, manage operating conditions, and prevent overheating-related damage. If temperature readings become inaccurate, the engine may trigger warning lights, fault codes, or reduced operation modes.
Key functions of the Cummins Temp Sensor (OEM 5461627) include:
- Monitoring engine or exhaust temperature in real time
- Supporting safe operation and overheating protection
- Helping regulate emissions system functions
- Assisting proper aftertreatment control when equipped
- Preventing fault codes caused by temperature irregularities
OEM 5461627 plays an essential role in engine protection and system reliability for Cummins QSB 6.7L and B6.7 engines from 2013 to 2018.
Yes, you can often still drive if a temperature sensor goes bad, but it should only be treated as a short-term option, not a long-term solution.
Temperature sensors play a major role in protecting the engine and controlling emissions functions. When one fails, the ECM may use default values to keep the vehicle running—but that can also cause incorrect operation and trigger protective modes.
What can happen if you keep driving with a bad temp sensor?
- Check engine / warning lights
- The ECM detects an implausible reading or signal loss.
- Limp / restricted mode
- Many vehicles derate to prevent engine or emissions damage when temperature data is unreliable.
- Cooling fan problems
- The fan may run constantly or not activate correctly, increasing overheating risk.
- Regeneration issues (if it’s an exhaust temp sensor)
- The DPF system may fail regeneration or attempt it too often because exhaust temperature can’t be monitored accurately.
- Poor drivability and higher fuel usage
- Incorrect temperature readings can affect fueling strategy and engine operation.
- Risk of overheating or component damage
- If it’s a coolant temp sensor, driving too long can lead to serious engine damage.
You may be able to drive short distances, but it’s not recommended to continue driving with a bad temp sensor. To avoid overheating, regen failure, or derate conditions, replacement should be handled as soon as possible.
Yes, it is a Cummins-specified temperature sensor designed for the QSB 6.7L and B6.7 engines.
Yes, the temperature sensor can typically be replaced on its own without changing other components.
Incorrect readings can lead to improper aftertreatment behavior and diagnostic trouble codes.
It helps the control unit decide when regeneration should occur based on exhaust temperature.
