Tamerx 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.

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, 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 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.

Fuel pressure irregularities can affect how a diesel injection system operates, making reliable pressure monitoring essential. The Yanmar 4TNV98C, 3.3L Fuel Rail Pressure Sensor 2014-2024: OEM 129A00-57100 measures pressure inside the common fuel rail and sends electronic signals to the engine control system, helping identify pressure changes that may require adjustment or diagnosis.
-
OEM 129A00-57100 is intended for compatible 2014-2024 Yanmar 4TNV98C 3.3L diesel applications.
-
Continuous pressure monitoring provides real-time information about fuel pressure within the common-rail system.
-
Electronic sensing technology converts fuel pressure measurements into signals the engine control unit can interpret.
-
Helps detect pressure irregularities by allowing the control system to recognize readings outside expected operating conditions.
-
Supports fuel-system diagnostics by providing pressure data that can assist in identifying abnormal fuel delivery conditions.
-
High-pressure sensing construction is suited for the demanding environment of a diesel common-rail injection system.
-
Secure electrical connections help maintain communication between the sensor and the engine control system.
-
Application-specific mounting and sealing surfaces help provide proper installation on compatible Yanmar 3.3L fuel rails.
The Yanmar 4TNV98C 3.3L Fuel Rail Pressure Sensor OEM 129A00-57100 provides essential pressure feedback for monitoring and diagnosing common-rail fuel-system conditions. Customers searching for a Yanmar 4TNV98C fuel rail pressure sensor, Yanmar 3.3L fuel pressure sensor, diesel common rail sensor, fuel injection pressure sensor, or OEM 129A00-57100 replacement can use this application-specific component to restore dependable fuel-pressure monitoring.
Unexpected engine power loss can occur when a faulty Fuel Rail Pressure Sensor sends incorrect pressure readings to the Engine Control Module (ECM). Since the ECM relies on this information to regulate fuel injection, inaccurate signals may disrupt fuel delivery, reduce engine performance, or trigger protective operating modes.
-
Incorrect fuel pressure readings: A malfunctioning sensor may report pressure values that do not match actual fuel rail conditions.
-
Sudden power reduction: Incorrect pressure information can cause the ECM to limit fuel delivery, resulting in an unexpected loss of engine power.
-
Engine derate: Severe or persistent fuel pressure faults may activate a reduced-power operating mode.
-
Poor acceleration: Unstable pressure signals can interfere with fuel injection control and cause sluggish engine response.
-
Engine hesitation: Intermittent sensor problems may cause hesitation or inconsistent power during acceleration.
-
Check engine light: Abnormal fuel pressure readings can trigger diagnostic trouble codes and activate engine warning lights.
-
Damaged wiring or connectors: Loose terminals, corrosion, or electrical faults can interrupt sensor signals and cause sudden performance changes.
A faulty Fuel Rail Pressure Sensor can contribute to sudden engine power loss, but fuel pumps, injectors, pressure control valves, and other fuel system components can produce similar symptoms. Comparing commanded and actual rail pressure while inspecting sensor signals, wiring, and related components can help identify the problem and restore reliable engine operation.
Incorrect readings during cranking may result from a sensor malfunction, unstable reference voltage, poor grounding, or an actual fuel-pressure problem. Diagnostic equipment can help determine whether the reading matches expected conditions.
The sensor continuously measures rail pressure as operating conditions change. Its signal allows the ECU to monitor whether actual pressure is responding appropriately to fuel-system demands.
Possible causes include damaged wiring insulation, loose connectors, electrical interference, poor grounding, or internal sensor deterioration. Electrical testing can help identify the source of abnormal voltage changes.
Corrosion can increase electrical resistance or interrupt communication between the sensor and ECU. This may cause inaccurate pressure readings or intermittent diagnostic faults.
