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"
Created to measure intake airflow with precision, the OEM 4984928 Mass Flow Sensor is designed for Cummins ISB 6.7L, ISL, and ISC engines. This sensor provides critical air volume data to the engine control module, helping maintain proper fuel calibration and steady operation across varying conditions. Its OEM-grade construction ensures accurate fitment, dependable signal clarity, and durability against heat, vibration, and environmental exposure. When symptoms such as sluggish response, irregular readings, or airflow-related diagnostic codes appear, this component offers a trustworthy replacement option. Built with high-quality materials and precise engineering, it supports consistent performance across all compatible Cummins applications.

What Is the Cummins Mass Flow Sensor (OEM 4984928)?
The Cummins Mass Flow Sensor (OEM 4984928) is a specialized monitoring device used on ISB 6.7L, ISL, and ISC engines. Its primary role is to measure the amount of air flowing into the engine’s intake system. This information is essential for the engine control module, which relies on accurate airflow data to manage combustion, emissions, and overall engine efficiency.
What the Mass Flow Sensor Does
The sensor detects the volume of incoming air and converts that measurement into an electrical signal. Because modern diesel engines require precise air-to-fuel ratios to operate cleanly and reliably, the mass flow sensor plays a key role in maintaining balanced engine operation. It helps determine fuel delivery, ensures correct turbocharger response, and supports emissions system performance.
Why This Sensor Is Important
- Maintains proper air-to-fuel ratio for smooth engine operation
- Supports accurate fuel control and timing
- Improves combustion efficiency and reduces soot formation
- Helps the emissions system function correctly
- Prevents problems such as rough idle or reduced acceleration
- Provides early warning signs when airflow is restricted or abnormal
The Cummins Mass Flow Sensor (OEM 4984928) is essential to the engine’s air management and emissions strategy. Without accurate airflow measurement, the engine cannot regulate combustion correctly, which may lead to poor performance, increased emissions, or diagnostic faults. Keeping this sensor in good working condition ensures dependable and efficient operation on ISB 6.7L, ISL, and ISC engines.
The Sensor Mass Flow, often called a Mass Air Flow (MAF) sensor, plays a critical role in helping your engine maintain the correct air-to-fuel mixture. When this sensor begins to fail, the engine’s computer receives incorrect data, leading to noticeable drivability concerns. Identifying these symptoms early can prevent further complications and unnecessary repairs.
A failing Sensor Mass Flow commonly causes the engine to run too rich or too lean, resulting in irregular behavior during everyday driving.
Common symptoms of a failing Mass Flow Sensor include:
- Rough or unstable idle
- Hard starting, especially in warm conditions
- Hesitation during acceleration
- Stalling at stops or while coasting
- Increased fuel consumption
- Black exhaust smoke from improper air-to-fuel ratios
- Check Engine Light tied to air metering fault codes
While some of these symptoms may overlap with other engine-related issues, a diagnostic scan can quickly confirm whether the Sensor Mass Flow is sending inaccurate readings.
If the sensor shows fluctuating data, incorrect airflow measurements, or fails to respond during testing, replacement is typically the most reliable solution.
It measures the volume of air entering the intake system so the ECM can calculate proper fuel delivery.
It is mounted in the intake duct where it can accurately measure incoming air volume.
Yes, buildup on the sensing element can distort airflow readings and cause drivability issues.
It should be checked during air restriction issues, uneven idle, or unexpected fuel consumption changes.
