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"
Used across 2000–2007 Caterpillar C7, C10, C12, and 3406E engine applications, the TPS Rotary Sensor (OEM 2661466) is an important part of the engine control system. This throttle position sensor tracks the rotary movement of the throttle or fuel control mechanism and relays precise position data to the engine control module. Accurate feedback allows the ECM to manage fuel delivery and engine response under varying operating conditions. Proper sensor operation helps support smooth throttle transitions, stable idle behavior, and consistent drivability. This page provides detailed application information for the Caterpillar TPS Rotary Sensor OEM 2661466, assisting with correct identification for service and replacement needs.

The Caterpillar TPS (Throttle Position Sensor) Rotary Sensor, OEM 266-1466, is a critical engine management component found on several mid-range Caterpillar diesel engines, including the C7, C10, C12, and 3406E models used between 2000 and 2007.
This sensor’s main job is to monitor the position of the throttle linkage or fuel rack, converting physical movement into electrical signals that the engine’s control system can understand. As the throttle or fuel rack moves, the rotary sensor detects its angle and sends a corresponding voltage signal to the engine controller.
Unlike simple switches, a rotary sensor measures continuous movement, enabling precise data feedback. This allows the engine’s control system to make informed decisions about fuel delivery and other operational parameters.
Key Functions of the Caterpillar TPS Rotary Sensor (OEM 266-1466):
- Monitors throttle linkage or fuel rack position
- Converts mechanical position into an electrical signal
- Sends real-time data to the engine control module
- Helps maintain consistent engine operation across load changes
- Works with other sensors for smooth system coordination
Because it directly informs the engine controller about throttle position, a failing sensor can lead to poor idle control, hard starting, irregular running, or diagnostic trouble codes. The OEM part ensures correct fitment and reliable signal output for the specified Caterpillar engines from 2000 to 2007.
You can prolong the lifespan of a TPS (Throttle Position Sensor) rotary sensor by protecting it from contamination, electrical stress, and mechanical wear. Because a TPS relies on precise voltage signals and smooth internal movement, small issues can shorten its service life if left unaddressed.
Here are the most effective ways to extend TPS rotary sensor lifespan:
- Keep moisture and contaminants out
- Water intrusion, dust, and oil vapor can damage internal contacts. Ensure seals, gaskets, and connector boots are intact and properly seated.
- Inspect wiring and connectors regularly
- Loose pins, corrosion, or chafed wiring can cause voltage spikes or signal dropouts that stress the sensor. Clean and secure connectors as needed.
- Avoid forced throttle movement
- Manually forcing throttle components during service can damage the rotary mechanism inside the sensor. Always follow proper service procedures.
- Maintain stable electrical supply
- Weak batteries, poor grounds, or charging system issues can cause erratic voltage that accelerates sensor wear.
- Address throttle body issues early
- Binding throttle plates or mechanical resistance force the TPS to work harder than designed, increasing internal wear.
- Respond quickly to drivability symptoms
- Hesitation, erratic throttle response, or warning lights should be diagnosed early to prevent extended sensor stress.
A TPS rotary sensor lasts longest when it stays clean, electrically stable, and mechanically unstressed through regular inspections and timely maintenance.
Yes, incorrect throttle position readings can lead to inconsistent engine behavior.
Yes, it monitors throttle position whenever the engine is operating.
Yes, damaged wiring or poor connections can result in incorrect sensor readings.
Yes, it is widely used across on-highway trucks and vocational equipment with these engines.
