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"
Engineered to capture accurate pressure data for critical engine functions, the OEM 2746719 Sensor GP-PR is suitable for a range of Caterpillar diesel applications. This sensor transmits essential readings to the engine control module, helping maintain balanced operation and proper system regulation under varying conditions. Its OEM-grade construction ensures precise fitment, dependable signal clarity, and durability against heat, vibration, and long-term exposure. When issues such as erratic readings, warning indicators, or pressure-related diagnostic codes appear, this sensor provides a trustworthy replacement option. Built with high-quality materials and exact engineering, it supports consistent performance across all compatible Caterpillar platforms.

The Caterpillar Sensor GP-PR (OEM 2746719) is a pressure sensor designed to monitor system pressure in various Cat engines and equipment. Its internal construction allows it to deliver precise, reliable readings even in harsh operating environments such as high heat, vibration, and exposure to oil or fuel.
To accomplish this, the sensor is built from several key components working together to convert mechanical pressure into an accurate electrical signal.
Key Components of the Sensor GP-PR
- Pressure-Sensitive Diaphragm
- A flexible internal membrane that reacts to changes in system pressure. As pressure increases or decreases, the diaphragm moves accordingly.
- Sensing Element (Strain Gauge / Transducer Chip)
- Attached to the diaphragm, this component converts the diaphragm’s movement into an electrical signal. It is the core measuring element of the sensor.
- Internal Circuit Board
- Processes and stabilizes the electrical output from the sensing element before sending it to the engine control module. It ensures consistent, noise-free signal transmission.
- Sensor Housing
- A rugged metal enclosure that protects internal electronics from heat, vibration, and contamination. It also serves as the threaded mounting point where the sensor installs into the engine system.
- Electrical Connector
- A sealed plug that connects the sensor to the wiring harness. It ensures a clean electrical link and protects against moisture, dust, and corrosion.
- Sealing Components (O-Rings / Gaskets)
- Provide a leak-proof seal between the sensor body and the system it monitors. Proper sealing ensures accurate pressure readings and prevents contamination from entering.
Why These Components Matter
Each part of the Sensor GP-PR plays a critical role in delivering accurate, reliable pressure data. If the diaphragm is damaged, the connector corrodes, or the circuit becomes unstable, the sensor may send incorrect readings—leading to performance issues, fault codes, or even engine protection events.
The Sensor GP-PR is responsible for monitoring system pressure and sending accurate data to the engine or equipment control module. When it begins to fail, the system may no longer receive reliable information, leading to noticeable changes in how your vehicle or equipment operates. Recognizing the early signs helps prevent more serious issues.
A failing Sensor GP-PR often creates pressure irregularities that the control module cannot correct properly.
Common signs your Sensor GP-PR may be failing include:
- Erratic or unstable pressure readings shown on diagnostics
- Warning lights connected to pressure or emissions systems
- Rough idle or hesitation during acceleration
- Unexpected drops in fuel efficiency
- Hard starting or stalling, especially when the engine is warm
- Fault codes indicating pressure deviations or sensor communication problems
In some cases, the symptoms may appear gradually, while in others the sensor may fail suddenly. A diagnostic scan is the most reliable way to confirm the issue, as it allows you to compare actual vs. expected pressure data.
If the sensor outputs fluctuating or inaccurate readings, or if it fails sensor tests, replacement is typically required to restore stable system operation.
It detects pressure in a specific engine or subsystem so the ECM can adjust operation based on real-time conditions.
It matches the electrical profile and pressure calibration required by several CAT monitoring circuits.
Fluctuating readings, system derates, or pressure-related fault codes may appear.
It threads into a designated pressurized port such as fuel, lubrication, or hydraulic passages depending on configuration.
