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"
Used on 2013–2018 Cummins QSB 6.7L, B6.7, and ISB engines, the Temp Sensor with OEM 5461634 is an integral part of engine and emissions control systems. This temperature sensor accurately measures exhaust or intake air temperatures and sends that data to the engine control module (ECM) to support proper fuel timing, combustion control, and aftertreatment system operation. Reliable temperature readings help the ECM manage combustion efficiency and emissions components, aiding in smoother transitions through operating conditions and maintaining emissions compliance. Consistent sensor performance can help reduce drivability issues, prevent unnecessary warning indicators, and support overall engine reliability. This page provides application-specific details to assist with identifying the Cummins QSB 6.7L, B6.7, and ISB Temp Sensor 2013–2018 (OEM 5461634) for accurate service and replacement needs.

The Cummins temperature sensor, OEM 5461634, is a monitoring sensor used on Cummins QSB 6.7L, B6.7, and ISB engines from 2013 to 2018. Its main job is to measure temperature in a specific engine or aftertreatment location and send that information to the engine control module (ECM).
This sensor doesn’t control temperature directly—it provides the data the system needs to make the right decisions.
- Step 1: The sensor detects heat changes
- Inside the sensor is a temperature-sensitive element (commonly a thermistor). As temperature rises or falls, the internal resistance changes.
- Step 2: Resistance is converted into an electrical signal
- The ECM supplies a reference voltage to the sensor. As resistance changes, the voltage signal returning to the ECM changes too. This allows the ECM to calculate the exact temperature reading.
- Step 3: The ECM uses the reading to manage engine operation
- Once the ECM receives the temperature signal, it can adjust system operation based on real-time conditions. Depending on where the sensor is installed, it may be used to:
- Monitor engine operating temperature
- Help protect components from overheating
- Support emissions system functions
- Control regeneration timing in aftertreatment systems
- Trigger warning lights or fault codes if readings are out of range
- Step 4: Safety and protection functions
- If the sensor reports abnormal readings—too hot, too cold, or unrealistic values—the ECM may set a diagnostic trouble code and in some cases limit operation to protect the engine.
The Cummins temp sensor (OEM 5461634) works by sensing temperature changes, converting them into an electrical signal, and sending that data to the ECM so the engine and aftertreatment systems can operate safely and efficiently.
Yes, you can often still drive if a temperature sensor goes bad, but it depends on which temp sensor failed and how the vehicle’s computer responds. In many cases, the vehicle will enter a protective mode because the engine and emissions systems rely heavily on accurate temperature readings.
A failed temp sensor can cause the ECM to use default values, which may allow driving temporarily—but it can also lead to overheating risk, improper fueling, or emissions system faults.
What can happen if you keep driving with a bad temp sensor?
Here are common outcomes:
- Check engine light and fault codes
- The ECM detects an implausible temperature reading or signal loss.
- Limp / restricted mode
- Many vehicles limit operation to prevent damage, especially if the sensor affects engine protection or regeneration control.
- Cooling fan running constantly or not running at all
- A bad sensor can cause incorrect fan operation, increasing overheating risk.
- Regeneration problems (if it’s an exhaust temp sensor)
- DPF regeneration may fail or trigger too often because exhaust temperature can’t be monitored correctly.
- Poor drivability and higher fuel usage
- Incorrect temperature readings can affect fueling strategy and engine efficiency.
- Risk of overheating or component damage
- If the sensor controls cooling or engine protection logic, driving too long can cause serious damage.
You may be able to drive short distances, but it’s not recommended to keep driving with a bad temp sensor. Since temperature sensors directly impact engine safety and emissions control, the safest move is to replace the sensor as soon as possible to avoid overheating, regeneration failure, or costly secondary damage.
It sends exhaust temperature data to help regulate aftertreatment operations.
Symptoms include erratic exhaust temperature readings and related fault codes.
Yes, inaccurate temperature data can affect SCR dosing and conversion accuracy.
The engine control unit uses the temperature data to adjust aftertreatment functions.
