Drive On Diesel 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 Drive On Diesel, 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). Drive On Diesel 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 Drive On Diesel, 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.

Caring for your Cummins B6.7 Temp Sensor (OEM 5654166-OE) is all about protecting its accuracy and ensuring it can consistently send reliable data to the engine’s control system. Since this sensor plays a direct role in monitoring temperature, even small issues can lead to incorrect readings or system warnings.
The good news is that it doesn’t require heavy maintenance—just regular attention and proper handling.
Here are practical ways to keep it working properly:
- Check the electrical connection
- Make sure the connector is tight and free from corrosion. A weak connection can lead to inconsistent or false readings.
- Keep the sensor area clean
- Dirt, oil, or coolant residue around the sensor can interfere with its ability to detect temperature accurately.
- Inspect wiring for damage
- Look for frayed wires, melted insulation, or signs of wear—especially since the sensor is exposed to heat and vibration.
- Monitor for unusual temperature readings
- Sudden fluctuations, warning lights, or irregular gauge behavior can indicate the sensor is starting to fail.
- Maintain the cooling and exhaust systems
- A properly functioning system helps prevent excessive heat, which can shorten the lifespan of the sensor.
- Handle with care during installation or removal
- Avoid overtightening or dropping the sensor, as it’s a sensitive component.
- Replace when reliability drops
- If the sensor begins giving inconsistent readings or triggers repeated alerts, timely replacement helps avoid bigger issues.
In simple terms, taking care of your Cummins 5654166-OE temp sensor means keeping it clean, connected, and protected—so it can continue providing accurate temperature data and support smooth engine operation.
A temperature sensor is responsible for sending accurate engine temperature data to the control system. When it starts to fail, it can cause incorrect readings and lead to a variety of engine-related issues.
Because this sensor directly influences fuel delivery and cooling system behavior, even minor faults can have noticeable effects.
Here are common signs of a bad temperature sensor:
- Inconsistent or erratic temperature readings
- The gauge may spike, drop suddenly, or show readings that don’t match actual engine conditions.
- Check engine light or diagnostic trouble codes
- The system may detect abnormal signals and trigger warnings related to temperature readings.
- Poor fuel efficiency
- Incorrect data can cause the engine to use more fuel than necessary due to improper adjustments.
- Hard starting or rough cold starts
- A faulty sensor can send incorrect signals during startup, making the engine harder to start or run unevenly.
- Engine overheating or false warnings
- The sensor may fail to detect real overheating or trigger alerts when there’s no actual issue.
- Rough idling or unstable engine behavior
- Inaccurate temperature input can lead to improper fuel-air adjustments, causing uneven performance.
Identifying these symptoms early helps prevent further complications. Replacing a faulty temperature sensor ensures accurate monitoring and supports proper engine operation.
Yes, inaccurate temperature data can lead to improper aftertreatment operation, affecting emissions control and system efficiency.
